=== '''The ghpsdr3-alex Project''' ===

This is a modification of the excellent Software Defined Radio (SDR) software by John Melton [G0ORX/N6LYT][http://g0orx.blogspot.com]

The original software by John is called ghpsdr3. We are working towards merging the two projects (ghpsdr3 and ghpsdr3-alex) source trees to a single source. However BEFORE that happens, you CANNOT mix and match programs from the two projects. See note for HPSDR hardware users below.

Project README https://github.com/alexlee188/ghpsdr3-alex/blob/master/README [https://github.com/alexlee188/ghpsdr3-alex/blob/master/README]

Source Code is via git at https://github.com/alexlee188/ghpsdr3-alex [https://github.com/alexlee188/ghpsdr3-alex]

Discussions take place in the sdr-widget group http://groups.google.com/group/sdr-widget [http://groups.google.com/group/sdr-widget]

You can browse the list of online dspservers at http://qtradio.napan.ca/qtradio/qtradio.pl[http://qtradio.napan.ca/qtradio/qtradio.pl]

You can view the map of online dspservers worldwide at http://www.montefusco.com/ghpsdr3[http://www.montefusco.com/ghpsdr3]

Currently it supports HPSDR, Softrock, UHFSDR, Microtelecom Perseus, SDR-iq, HiQSDR, Ettus Research USRP and [[RTL-SDR|rtl-sdr]] DVB-T dongles.

=== '''What is the actual ghpsdr3-alex Project software?''' ===

The software comprises 3 different components:

'''A)''' server - there is a CLI based server for each type of hardware. For example, there are hpsdr-server, usrp-server, softrock (server), sdriq-server, HiQSDR etc. Some servers are based on soundcard/USB connections to the hardware. Some are connected via ethernet (eg HPSDR Metis).

'''B)''' dspserver - this is the software in the middle that processes the IQ data from the server (connected over LAN via UDP) using DttSP. The same dspserver can connect to any of the servers in A.

'''C)''' clients - this is the GUI user interface. There are clients built with Qt and runs on Windows, Linux, and Mac OSX. There is a working Android client that works on Android phones and Android tablets. The clients connect to dspserver via LAN or remotely via Internet. In future we will have java based web clients as well (either specifically written clients, or running Qt inside a web browser) Also, multiple clients can concurrently access the same dspserver. There is also RxTx capability (currently for voice modes). the QtRadio client has a Hamlib interface and can connect to gPredict, xLog, and fldigi (for digital mode). See [[Configuration Data for QtRadio Hamlib Clients]].

'''Project Goals'''

1. Open source (GPL) SDR software

2. Client-server network-enabled by design from the ground up

3. Customized server for each SDR hardware type. Currently supporting HPSDR, Softrock, UHFSDR, Microtelecom Perseus, RFSPACE SDR-IQ, HiQSDR, Ettus Research USRP, and the rtl-sdr DVB-T dongle.

4. Single dspserver that connects to single server. However, each server can have multiple Rx and Tx channels.

5. Multiple clients, such as QtRadio, that can concurrently connect to a single dspserver.

6. Full Rx and Tx capability for hardware capable of Tx

'''Note for HPSDR and ghpsdr3 (original) users:'''
In general, you cannot mix and match software from the two projects, ghpsdr3 and ghpsdr3-alex. However, John has updated the programs in the ghpsdr3-alex repository, and the hpsdr-server program in gphsdr3-alex works for HPSDR hardware. The following newbie guide is written by Erich Heinzle (vk5hse at yahoo.com):

QtRadio Installation

2015-06-11T20:14:21Z

Iw0hdv: /* Building the Perseus extensions */

== Installation on Linux ==
The instructions below are for Debian based distributions like Ubuntu but you should be able to compile on any Linux distribution with the correct libraries installed.

=== Installation from Git ===
Installing from git involves building or compiling from source. This is required if you want to use one of the various branches to work the "bleeding edge" branches like Alex's rxtx-event branch where the current (Nov 12 2011) TX work is being done.
The PPA install is never more than a few days behind master so there is not much to gain from building from git unless you want to work with the source code your self.

==== Installing compiler and autotool ====

First off, install the compiler; depending on which distribution are you using, some or all of this stuff could be already installed:

===== Ubuntu/Debian =====
<pre>
sudo apt-get install make gcc g++
sudo apt-get install autoconf automake autotools-dev libtool git subversion
</pre>

===== Fedora =====
<pre>
sudo yum install gcc gcc-c++ man-pages autoconf automake subversion libtool git
</pre>

==== Installing prerequisite packages ====

===== Ubuntu 12.04 and newer =====
First of all, you have to check that the universe repository is enabled. Click on the gear shaped icon (bottom into left side bar): the System Settings menu will shown, click on Software Sources and finally check the Community-maintained Open Source Software (universe) tick. Next, submit the following commands into a terminal window:

<pre>
sudo apt-get update
sudo apt-get install \
libqt4-opengl-dev \
qtmobility-dev \
libusb-0.1-4 \
libusb-dev \
libfftw3-dev \
portaudio19-dev \
libpulse-dev \
libsamplerate0-dev \
libusb-1.0-0-dev \
libconfig8-dev \
xdg-utils \
libortp-dev \
gcc-multilib \
libssl-dev \
libevent-dev \
libglu1-mesa-dev \
freeglut3-dev \
cmake \
libspeexdsp-dev \
libxcb-composite0-dev

### libspeexdsp-dev is only required for codec2-dev. DO NOT USE codec2-dev - it is the development branch and may or may not work as the developers have warned --- use "codec2" which is the stable branch.

</pre>

You will need qt5 installed to complete the build.

Visit: http://qt-project.org/downloads

download the current package for your system.

To build Qt5 on a RaspberryPi visit: http://qt-project.org/wiki/RaspberryPi

After downloading it go to the download directory and do:
<pre>
$ chmod +x the-name-of-the-downloaded-file
$ sudo ./the-name-of-the-downloaded-file
</pre>

Simply click on the installer and follow the prompts, take note of were qt5 is installed. Don't open the readme or start QtCreator when the installer asks. It will make some files in your home directory owned by root, and that will give you trouble later. After the install has completed, from a terminal:
<pre>
$ export PATH=/opt/Qt5.1.0/5.1.0/gcc_64/bin:/opt/Qt5.1.0/Tools/QtCreator/bin:$PATH
</pre>
In the above make sure you put in the correct path for your version of Qt. This is due because the several packages from Qt sources and binary repositories web sites are not really installed in the system but simply copied on it. Therefore the autotools build system should search virtually over the whole filesystem.
In any case please remember that
the export above is effective only into the current terminal windows, if you open another window and/or reboot the system, you have to resubmit again the command
if you want to make permanent it, you have to add the export into the right configuration shell, suitable for the shell that you are currently using.
For the bash it is typically ~/.bashrc
In any case, after you issue the export, please test it.
<pre>
qmake -v
QMake version 2.01a
Using Qt version 4.8.0 in /home/andrew/QtSDK4.8x/Desktop/Qt/4.8.0/gcc/lib
</pre>

===== Ubuntu 11.04 and older =====
First of all, you have to check that the ''universe repository'' is enabled.
Please see the procedure in the previous section [[#graphical installation]] .

Next, you will need the following packages installed:

<pre>
sudo apt-get update
sudo apt-get install \
libqt4-opengl-dev \
qtmobility-dev \
libusb-0.1-4 \
libusb-dev \
libfftw3-dev \
portaudio19-dev \
libpulse-dev \
libsamplerate0-dev \
libusb-1.0-0-dev \
libconfig8-dev \
libortp-dev \
cmake
</pre>

===== Ubuntu 11.10 =====
First of all, you have to check that the ''universe repository'' is enabled.
Click on the gear shaped icon (bottom into left side bar): the ''System Settings'' menu will shown, click on ''Software Sources'' and finally check the ''Community-maintaned Open Source Software (universe)'' tick.
Next, submit the following commands into a terminal window:

<pre>
sudo apt-get update
sudo apt-get install \
libqt4-opengl-dev \
qtmobility-dev \
libusb-0.1-4 \
libusb-dev \
libfftw3-dev \
portaudio19-dev \
libpulse-dev \
libsamplerate0-dev \
libusb-1.0-0-dev \
libconfig8-dev \
xdg-utils \
libortp-dev \
cmake
</pre>

===== Fedora 16 and newer ** AVOID CentOS ** It is not a Desktop OS =====

<pre>
sudo yum install fftw fftw-devel
sudo yum install libusb-devel libusb1-devel
sudo yum install portaudio-devel
sudo yum install libconfig-devel
sudo yum install libsamplerate-devel
sudo yum install pulseaudio-libs-devel
sudo yum install jack-audio-connection-kit jack-audio-connection-kit-devel
sudo yum install qt4-devel
sudo yum install libevent
sudo yum install libevent-devel
sudo yum install cmake

Qt5 is needed to build QtRadio. If the distro does not include qt5, follow the build instructions in the section ODROID - OK for all platforms.
Check if Qt5 is supplied "sudo yum install qt5*" - it is available in Fedora 20.
</pre>

==== Cloning the repository ====

How to build the latest master branch on Ubuntu 11.04

First a new libevent will need to be downloaded and installed, then the actual QtRadio source can be downloaded and built.

==== Obtaining an up-level libevent library ====

$ sudo apt-get install libevent-dev

If the version is older than 2.0.5, go to synaptic and completely remove the stock libevent from Ubuntu. (Completely remove is an uninstall option in Synaptic. Additional dependent libraries may also be removed)

Then download the new version from:

http://libevent.org/

libevent-2.0.16-stable.tar.gz

<pre>
wget https://github.com/downloads/libevent/libevent/libevent-2.0.16-stable.tar.gz
</pre>

Move the tarball from the Downloads directory to a working directory. A suggestion is to create a src directory within your home directory and move it there. Uncompress and follow the instructions to build and install:

<pre>
cd
tar -zxvf libevent-2.0.16-stable.tar.gz
cd libevent-2.0.16-stable
./configure
make
sudo make install
sudo ldconfig
</pre>

On Fedora, in order to use the library above, export the LD_LIBRARY_PATH:

<pre>
export LD_LIBRARY_PATH=/usr/local/lib
</pre>

==== Installing codec2 low bit rate audio encoding and decoding ====

We are adding a low bit rate audio codec called codec 2 to QtRadio/dspserver. You need
to download and build the codec2 library. See:

http://www.rowetel.com/blog/?page_id=452

Now go get codec2 using subversion

<pre>
svn co https://svn.code.sf.net/p/freetel/code/codec2 codec2
cd codec2

mkdir build
cd build
cmake ../

sudo make
sudo make install
sudo ldconfig
</pre>

On some variations codec2 files will not be detected as installed correctly; if build errors citing codec2 are encountered during the later ./configure steps:

<pre>
cd /usr/local/include/codec2

sudo cp * ..
</pre>

'''IMPORTANT NOTE: If build errors persist referencing any codec2 missing components, please consider http://napan.ca/ghpsdr3/index.php/QtRadio_Installation#Refresh_to_a_Newer_Version procedure before continuing.'''

On Fedora, in order to use the library above, export the LD_LIBRARY_PATH:

<pre>
export LD_LIBRARY_PATH=/usr/local/lib
</pre>

==== Building the master branch ====

This branch is the latest code that contains both RX and TX capability.

Create a new directory or cd to the ~/src directory created for libevent and cd into it.

<pre>
git clone git://github.com/alexlee188/ghpsdr3-alex
</pre>

Depending on your Internet connection thorughput, it will take several minute to download.
cd into the new directory ghpsdr3-alex:
<pre>
cd ghpsdr3-alex
git checkout master
</pre>
You are now working with Alex's latest and greatest!

First set the path to the version of qt you are using. E.g. for qt5:
<pre>
$ export PATH=/opt/qt5/bin:$PATH
</pre>

Then:
<pre>
autoreconf -i
./configure.sh
make -j4 all
sudo make install
</pre>
The default configure above builds with debug and default Qt4 version in your PC. For optimized executable,
you need to specify options specific to your system. See the sample shell scripts that replaces the above
./configure step:

<pre>
./alex-conf.sh if you have problems finding codec2
./alex-avx-conf.sh for building with i3,i5 and i7 cpu's supporting Advanced Vector Extensions (AVX)
./alex-openmp-conf.sh for building with i3,i5 and i7 cpu's and OpenMP support
./alex-sse3-conf.sh for building with SSE3 capable cpu's
./alex-openmp-sse3-conf.sh for building with SSE3 cpaable cpu's and OpenMP support
</pre>

(If you do not want to actually install the executable binaries, skip the sudo make install and just cd into the following directories and run them from there)
<pre>
Terminal 1
$ cd ghpsdr3-alex/trunk/src/softrock
$ ./softrock ...options ...

Terminal 2
$ cd ghpsdr3-alex/trunk/src/dspserver
$ ./dspserver ..options...

Terminal 3
$ cd ghpsdr3-alex/trunk/src/QtRadio
$ ./QtRadio
</pre>

==== Building the Perseus extensions ====

In order to build the Microtelecom Perseus server you need to switch to the master or iw0hdv branch.

First off, install the prerequisite library and wget package:

<pre>
sudo apt-get install libboost-all-dev wget
</pre>

Next download, compile and install the library libperseus-sdr:

<pre>
cd
wget http://libperseus-sdr.googlecode.com/files/libperseus_sdr-0.6.tar.gz
tar -zxvf libperseus_sdr-0.6.tar.gz
cd libperseus_sdr-0.6/
./configure && make
sudo make install
sudo ldconfig
</pre>

If you already build in your sandbox some other branch, is strongly advisable, before you start the build, to do a full cleanup:
<pre>
cd ~/ghpsdr3-alex
make distcheck && sh cleanup.sh
</pre>

Otherwise, if you are starting from scratch, you have to clone the repository:

<pre>
git clone git://github.com/alexlee188/ghpsdr3-alex
</pre>

Finally, you can switch to the master branch and rebuild everything; you don't need anymore to explicitly enable the perseus server feature, the configure script automatically selects it when the libperseus_sdr is found.

<pre>
cd ~/ghpsdr3-alex
git checkout master
autoreconf -i && ./configure && make -j4
sudo make install
</pre>

In order to run it you have two choices, the first one being the plain command line:

<pre>
xterm -e 'perseus_server -d3 -s96000 ' &
sleep 3
xterm -e 'dspserver --lo 0 --nocorrectiq' &
sleep 5
$( QtRadio -s 127.0.0.1 )
</pre>

In QtRadio, Receiver menu, select Configure item, Server tab: here add the local host using the 127.0.0.1 IP address.
Pressing the key C, you start the receiver.

The second choiche is to use the ghpsdr3-mgr.py script (available in menu Applications, Hamradio as ghpsdr3launcher): clicking on the Perseus icon the three processes should start and the QtServer automatically connects to Perseus Server.

==== Building USRP enabled version ====

===== Building the UHD package =====

====== Install the prerequisite packages (Ubuntu 11.10): ======

<pre>
sudo apt-get install liboost-all-dev
sudo apt-get install python-cheetah
</pre>

====== Build & Install UHD -- FOR UHD-3.3.1 AND GREATER --: ======

<pre>
cd
git clone git://ettus.sourcerepo.com/ettus/uhd.git
cd uhd/host/
mkdir build
cd build
cmake ../
make
make test
sudo make install
sudo ldconfig
</pre>

If you already build in your sandbox some other branch, is strongly advisable, before you start the build, to do a full cleanup:
<pre>
cd ~/ghpsdr3-alex
make distcheck && sh cleanup.sh
</pre>

Otherwise, if you are starting from scratch, first clone the repository:

<pre>
git clone git://github.com/alexlee188/ghpsdr3-alex
</pre>

Finally, you can switch to the master branch and rebuild everything, enabling the usrp server feature:
<pre>
cd ~/ghpsdr3-alex
git checkout usrp-server
autoreconf -i && ./configure --enable-usrp=yes && make -j4
sudo make install
</pre>

==== Refresh to a Newer Version ====

To pull a new version to build
<pre>
$ git pull
$ make -j4 all
$ sudo make install
</pre>
If extensive changes have occurred or if you get errors during the make, you may want to do a clean build
<pre>
$ git pull
$ make distclean
$ sh cleanup.sh
$ autoreconf -i
$ ./configure
$ make -j4 all
$ sudo make install
</pre>
If you continue to get errors, please report the whole ./configure output and the config.log to the mailing list.

== Installation on Windows ==
See [[ QtRadio on Windows]]

==VirtualBox Easy Installation==

It is possible to run the server software (and QtRadio) under VirtualBox. It has been tested with HPSDR Hermes hardware. [http://people.wallawalla.edu/~Rob.Frohne/ghpsdr3-alex/Ubuntu%2012.10%20ghpsdr3-alex-hermes.zip A VirtualBox Ubuntu 12.10 image] is available that automatically starts the server software for those who are running Windows, or don't feel they have the hardware, expertise or time to setup a Linux machine to act as a server. The username is: "ubuntu" and the password: "hamradio", which is probably a good thing to change soon after installation. Basically, all you need to do is follow the instructions below, plug your HPSDR Hermes or Apache Labs ANAN series transceivers into the network with the server, and you can be using ghpsdr3-alex on your own server. Users of older HPSDR hardware may need to make slight variations such as configuring USB in VirtualBox, specifying different command line arguments to the automatically started server commands, etc, but you won't have to build the software, or install Linux, or get another computer just to run the ghpsdr3-alex server software.

To get started, download the [http://people.wallawalla.edu/~Rob.Frohne/ghpsdr3-alex/Ubuntu%2012.10%20ghpsdr3-alex-hermes.zip VirtualBox image] (about 2.7 GB), unzip it, start [https://www.virtualbox.org/ VirtualBox], select the blue new button for the new machine, follow the wizard's instructions. When it asks you about the hard drive, say use existing virtual hard drive file, and select the image you just unzipped using the folder icon with the green up-arrow as the hard drive, and hit the create button. Then use the green start arrow to start the Ubuntu 12.10 virtual machine.

You should now be able to start QtRadio (the brown unity launcher item with CQ in it) and connect to your server. If that works, you should be able to connect from any client with network access to your server including QtRadio outside your virtual machine, or from another computer on your LAN or glSDR on your phone using WIFI. Be sure to set the server IP address in the client (QtRadio, or glSDR) to the IP address of the Ubuntu virtual machine. You can get the IP address from the up/down arrow menu on the upper left of your virtual machine menu bar, under the selection "Connection Information."

The [[Dspserver.conf]] file should be edited to personalize your server, and to allow transmit.

If your sever doesn't work, it may because your network interface is not eth2. If it isn't, you need to read the notes on the [[Hermes]] page, and then edit the commands used to automatically start your server as described in the paragraph immediately below. Another problem may occur because the SSL keys need to be generated. You can learn how to do that [[SSL Key Generation|here]].

If you want to edit or add the automatically started programs, see [http://askubuntu.com/questions/48321/how-do-i-start-applications-automatically-on-login this web page]. If you want to change things, the helpful notes about running the [[Hermes]] server on the [[Hermes]] page might be good to review. They explain the commands started automatically upon login.

I must make one note about running the software from a pre-prepared VirtualBox Image. It is a way an attacker could gain access to your computer and network. I used a pre-prepared Ubuntu 12.10 image from [http://virtualboxes.org/images/ubuntu/ VirtualBoxImages]. I believe it to be virgin, but you have to realize that it is possible that some rogue software is running on this image. If you use the image I provide, you must be solely responsible for whatever happens. I (Rob Frohne, KL7NA) did not put anything on the image, except the ghpsdr3-alex and the tools and packages, and configuration files needed to build it, and I believe it to be harmless. As always, there is a trade off between ease of use, and security.

== Network settings ==
If you are behind a firewall/NAT-router and want to be able to connect to your dspserver over the Internet you have to open up port tcp/8000. If you are using the client in RTP mode you have to open up udp/5004 and udp/5005.

== Installing ghpsdr3-alex on Raspberry Pi ==

===Hardware===

*** THIS SECTION DEALS WITH Raspberry Pi DIFFERENCES *** IT DOES NOT CIRCUMVENT THE INSTRUCTIONS STARTING AT STEP 1 OF THE QtRadio Installation. ***

I recommend installing either the raspbian or raspbian pisces (debian) distributions as there is no Ubuntu release to date.

*** All the pre-requisite packages needed for Ubuntu must be installed on raspbian or respbian pisces using the same "apt-get install" commands so it's necessary to follow the QtRadio-Installation
document from the beginning after installing raspbian or raspbian pisces.

The RasPi USB subsystem is sensitive to power supply voltage levels - A supply of 5.5V at 2A is recommended.
With the power supply output at +5.17V I was getting on-board Ethernet errors and system hangs when one more device besides keyboard and mouse were plugged in to the on-board USB ports or an outboard powered USB HUB.

Measuring the voltage across TP1 and TP2 on the Raspberry Pi and increased it to +4.97V (P.S output +5.59V).

I also ran "rpi-update" which install new firmware.

I shorted out the polyfuses F1 and F2 on the Pi and USB is much more stable but still limited.

With keyboard, mouse, gigabit USB Ethernet, SB Live! 24 USB and RTL-SDR dongle it runs for some hours before it freezes.

Removing the RTL-SDR dongle from the powered hub made a great difference with a current uptime heading for 3 days. The latest ghpsdr3-alex master branch build successfully completed while I was in bed.

One problem remains, no sound from the on-board chip.

===Software===
***** START AT THE BEGINNING WHEN BUILDING THE SOFTWARE -- i.e Section 1 and install all the packages recommended and do the pulseaudio setup.

If you build ghpsdr3-alex already it's a case of following the same procedure with the following caveats that apply to the RasPi ARM architecture. What follows is a blow by blow account of how I did it for the iw0hdv branch which supports my HiQSDR+Preselector. The same steps are needed for building any other branch.

Subject: [n2adr-sdr] Raspberry Pi running ghpsdr3-alex

The changes made by Andrea have been merged into the master branch. These changes allow samplerates >192K but the Pi doesn't have the power to run these high samplerates - I am running hiqsdr-server at 960K samplerate on a 8-core x84_64 box.

autoreconf -i

./configure CFLAGS='-O3 -pipe -march=armv6 -mfpu=vfp -mfloat-abi=hard' CXXFLAGS='-O3 -pipe -march=armv6 -mfpu=vfp -mfloat-abi=hard'

**** Additional steps needed when building rtlsdr-server. Do these before running make ******
# export ac_cv_func_malloc_0_nonnull=yes
# export ac_cv_func_realloc_0_nonnull=yes

make all && make all install

Sound on the Raspberry Pi is still a problem I have not been able to solve.

Terry (WB4JFI) suggested the following that work for him but I have had no luck with it.

"amixer cset numid=3 1"

Other valid numid's are 0=auto, 1=headphones and 2=hdmi.

QtRadio running on another box using the connection from the server list. Sound is a touch distorted, quite distorted on start up of QtRadio and spectrum is always a little bit slow.

When a slave connected and tried changing frequency, dspserver crashed - dspserver can be a bit crash happy.

The first thing I tried on the Pi was QtRadio standalone, spectrum and waterfall were OK but no sound.

Just now a client using glSDR (5) is attempting to change frequency, sound went quite distorted then dspserver crashed.

Restarted dspserver and QtRadio sound started very distorted before it settled down to reasonable.

= Installing portaudio19-dev with jackd2 =

Portaudio19-dev depends on having a copy of libjack-dev installed and if the libkjack-jackd2-dev package is installed before portaudio19-dev it's dependency will be satisfied and it will not uninstall jackd2 and install jackd1 if you have already installed jackd2 on your system.

== If jackd1 and portaudio19-dev already installed ==

<pre>From Synaptic

Uninstall portaudio19-dev
Uninstall jackd1
Install Jackd2
Install libjack-jackd2-dev
Install portaudio19-dev
</pre>

== If you are starting from scratch ==

<pre>From Synaptic

Install Jackd2
Install libjack-jackd2-dev
Install portaudio19-dev
</pre>

The following commands install all the environment needed (Debian/Ubuntu):

<pre>
sudo apt-get install jackd2 libjack-jackd2-dev portaudio19-dev

sudo apt-get install make gcc g++ autoconf automake autotools-dev libtool git subversion
sudo apt-get install libusb-0.1-4 libusb-dev libfftw3-dev libpulse-dev libsamplerate0-dev
sudo apt-get install libusb-1.0-0-dev libconfig8-dev xdg-utils libortp-dev
sudo apt-get install libevent-dev

</pre>

'''If the machine doesn't have an OpenGL aware accelerated video card, please install also the following packages:'''

<pre>
sudo apt-get install mesa-utils
sudo apt-get install mesa-common-dev
sudo apt-get install libgl1-mesa-dev
sudo apt-get install x11proto-xext-dev
sudo apt-get install libxrender-dev
</pre>

Note: in at least one case (thanks to Pierluigi iw4blg), even if the machine was running with an NVidia card and proprietary NVidia device drivers, the test for Qt in configure did fail, as well did the example programs enclosed in qt5 package, complaining that both GL/gl.h and libGL were missing. Installing all the above packages the problem was solved.

==== Installing codec2 low bit rate audio encoding and decoding ====

To download and build the codec2 library. See:

http://www.rowetel.com/blog/?page_id=452

Now go get codec2 using subversion

<pre>
cd
svn co https://freetel.svn.sourceforge.net/svnroot/freetel/codec2-dev
cd codec2-dev
autoreconf -i
./configure
make
sudo make install
sudo ldconfig
</pre>

= Installing Qt5 =

http://qt-project.org/downloads

U should download the Qt5.0.0 libraries file. 64 bit for x86_64 and 32 bit for x86 PC etc.

After downloading you go to the download directory and do:

$ chmod +x the-name-of-the-downloaded-file

$ sudo ./the-name-of-the-downloaded-file

After that you should have something installed in /opt/Qt5.0.0

== Setting the path to qt5 ==

From a terminal
<pre>
$ export PATH=/opt/Qt5.0.0/5.0.0/gcc_64/bin:/opt/Qt5.0.0/Tools/QtCreator/bin:$PATH
</pre>

This is due because the several packages from Qt sources and binary repositories web sites are not really ''installed'' in the system but simply copied on it.
Therefore the autotools build system should search virtually over the whole filesystem.

In any case please remember that

* the export above is effective only into the current terminal windows, if you open another window and/or reboot the system, you have to resubmit again the command

* if you want to make permanent it, you have to add the export into the right configuration shell, suitable for the shell that you are currently using.
For the bash it is typically ~/.bashrc

In any case, after you issue the export, please test it.
<pre>
qmake -v
QMake version 2.01a
Using Qt version 4.8.0 in /home/andrew/QtSDK4.8x/Desktop/Qt/4.8.0/gcc/lib
</pre>

== Compiling QtRadio ==
<pre>
cd
git clone https://github.com/alexlee188/ghpsdr3-alex.git
cd ghpsdr3-alex
git checkout master

sh ./cleanup.sh
autoreconf -i

sh ./alex-conf.sh

</pre>

Last, build everything:

<pre>
make
sudo make install
</pre>

== Setting QtCreator to use the qt5 libraries ==

If you want to use Qt Creator (you use the same Qt Creator as with Qt4), you need to configure it to use Qt5 as one of the options:
<pre>
From the top line menu of QtCreator ...

Tools > Options > Build & Run
Click on the Qt Versions panel
Click on Add button
Navigate to /opt/Qt5.0.0/5.0.0/gcc_64/bin
Click on qmake
Click on open
Click on Apply then OK
</pre>
You need to point to the qmake file which is found in /opt/Qt5.0.0/5.0.0/gcc_64/bin

== Choosing the build library in QtCreator ==

you need to (re)import your QtRadio project and then you will be able to select Qt5 (or the previous Qt4.8 etc.) for building the application.

It may be necessary to edit the project file (QtRadio.pro) to choose which version of Qt Creator you are using which can be the SDK directly from Nokia, or the Ubuntu install of Creator. The line "_UsingSDK" needs to be set to true or false as appropriate.

cd codec2
autoreconf -i
./configure
make
sudo make install
sudo ldconfig
</pre>

= Installing Qt5 =
You need to add the unsupported packages to your system. It will exist as a stand alone system separate from any other version of qt or creator etc. that you may have installed.

== Adding the qt5 “Canonical Qt5 Edgers” ppa to your system ==

In a terminal, copy and paste ...
<pre>
sudo add-apt-repository ppa:canonical-qt5-edgers/qt5-daily
</pre>
Your system will now fetch the PPA's key. This enables your Ubuntu system to verify that the packages in the PPA have not been interfered with since they were built.

Now, as a one-off, you should tell your system to pull down the latest list of software from each archive it knows about, including the PPA you just added:
<pre>
sudo apt-get update
</pre>
Now you're ready to start installing software from the PPA!

== Installing from the ppa ==

You will be installing the packages from the daily build of qt5 and the version date etc. could change but it is important to check that you have marked for install the package corresponding to the qt5 build as some of the packages may also be installed for qt 4.8.x A good check is to open the url for the Edgers and compare your selection to their file list at [https://launchpad.net/~canonical-qt5-edgers/+archive/qt5-daily canonical-qt5-edgers]

The packages will be identified with similar to
5.0-2012xxx ubuntu5 Zoltan Balogh (2012-04-05)
I have shown the example on the first entry in the list only.

Open Synaptic and use the quick find to look for and mark for install each of the packages in the following list ...
<pre>
qt-components-qtquick2 5.0-2012xxx ubuntu5 Zoltan Balogh (2012-04-05)
qt3d
qtbase
qtdeclarative
qtdoc
qtjsbackend
qtmultimedia
qtquick1
qtscript
qtsvg
qttools
qtwebkit
qtxmlpatterns

These packages will install by default in /opt/qt5
</pre>
note: there are a couple of packages which you do not need to install.

If you are using the command line, the needed command are shown below for convenience:

<pre>
sudo apt-get install qt-components-qtquick2 qt3d qtbase
sudo apt-get install qtdeclarative qtdoc qtjsbackend qtmultimedia qtquick1
sudo apt-get install qtscript qtsvg qttools qtwebkit qtxmlpatterns
</pre>

== Setting the path to qt5 ==

From a terminal
<pre>
$ export PATH=/opt/qt5/bin:$PATH
</pre>

== Compiling QtRadio ==

<pre>
cd
git clone https://github.com/alexlee188/ghpsdr3-alex.git
cd ghpsdr3-alex
git checkout master

sh cleanup
autoreconf -i
./configure CFLAGS='-fopenmp -O3 -msse3' CXXFLAGS='-fopenmp -O3 -msse3'

</pre>

for those of us with older machines use the line below instead:

<pre>
./configure CXXFLAGS='-O3 -msse2 -fopenmp'
</pre>
Last, build everything:

<pre>
make
sudo make install
</pre>

== Setting QtCreator to use the qt5 libraries ==

If you want to use Qt Creator (you use the same Qt Creator as with Qt4), you need to configure it to use Qt5 as one of the options:
<pre>
From the top line menu of QtCreator ...

Tools > Options > Build & Run
Click on the Qt Versions panel

Click on qmake
Click on open
Click on Apply then OK
</pre>
You need to point to the qmake file which is found in /opt/qt5/bin

you need to (re)import your QtRadio project and then you will be able to select Qt5 (or the previous Qt4.8 etc.) for building the application.

It may be necessary to edit the project file (QtRadio.pro) to choose which version of Qt Creator you are using which can be the SDK directly from Nokia, or the Ubuntu install of Creator. The line "_UsingSDK" needs to be set to true or false as appropriate.

= Installing portaudio19-dev with jackd2 =

Portaudio19-dev depends on having a copy of libjack-dev installed and if the libkjack-jackd2-dev package is installed before portaudio19-dev it's dependency will be satisfied and it will not uninstall jackd2 and install jackd1 if you have already installed jackd2 on your system.

== If jackd1 and portaudio19-dev already installed ==

<pre>From Synaptic

Uninstall portaudio19-dev
Uninstall jackd1
Install Jackd2
Install libjack-jackd2-dev
Install portaudio19-dev
</pre>

== If you are starting from scratch ==

<pre>From Synaptic

Install Jackd2
Install libjack-jackd2-dev
Install portaudio19-dev
</pre>

The following command install all the environment needed:

<pre>
sudo jackd2 libjack-jackd2-dev portaudio19-dev

sudo apt-get install make gcc g++ autoconf automake autotools-dev libtool git subversion
sudo apt-get install libusb-0.1-4 libusb-dev libfftw3-dev libpulse-dev libsamplerate0-dev
sudo apt-get install libusb-1.0-0-dev libconfig8-dev xdg-utils libortp-dev
sudo apt-get install libevent-dev

</pre>

If the machine doesn't have an OpenGL aware video card, please install also the following packages:

<pre>
sudo apt-get install mesa-utils
sudo apt-get install mesa-common-dev
sudo apt-get install libgl1-mesa-dev
sudo apt-get install x11proto-xext-dev
sudo apt-get install libxrender-dev
</pre>

==== Installing codec2 low bit rate audio encoding and decoding ====

To download and build the codec2 library. See:

http://www.rowetel.com/blog/?page_id=452

Now go get codec2 using subversion

<pre>
cd
svn co https://freetel.svn.sourceforge.net/svnroot/freetel/codec2
cd codec2
autoreconf -i
./configure
make
sudo make install
sudo ldconfig
</pre>

= Installing Qt5 =
You need to add the unsupported packages to your system. It will exist as a stand alone system separate from any other version of qt or creator etc. that you may have installed.

== Adding the qt5 “Canonical Qt5 Edgers” ppa to your system ==

In a terminal, copy and paste ...
<pre>
sudo add-apt-repository ppa:canonical-qt5-edgers/qt5-daily
</pre>
Your system will now fetch the PPA's key. This enables your Ubuntu system to verify that the packages in the PPA have not been interfered with since they were built.

Now, as a one-off, you should tell your system to pull down the latest list of software from each archive it knows about, including the PPA you just added:
<pre>
sudo apt-get update
</pre>
Now you're ready to start installing software from the PPA!

== Installing from the ppa ==

You will be installing the packages from the daily build of qt5 and the version date etc. could change but it is important to check that you have marked for install the package corresponding to the qt5 build as some of the packages may also be installed for qt 4.8.x A good check is to open the url for the Edgers and compare your selection to their file list at [https://launchpad.net/~canonical-qt5-edgers/+archive/qt5-daily canonical-qt5-edgers]

The packages will be identified with similar to
5.0-2012xxx ubuntu5 Zoltan Balogh (2012-04-05)
I have shown the example on the first entry in the list only.

Open Synaptic and use the quick find to look for and mark for install each of the packages in the following list ...
<pre>
qt-components-qtquick2 5.0-2012xxx ubuntu5 Zoltan Balogh (2012-04-05)
qt3d
qtbase
qtdeclarative
qtdoc
qtjsbackend
qtmultimedia
qtquick1
qtscript
qtsvg
qttools
qtwebkit
qtxmlpatterns

These packages will install by default in /opt/qt5
</pre>
note: there are a couple of packages which you do not need to install.

If you are using the command line, the needed command are shown below for convenience:

<pre>
sudo apt-get install qt-components-qtquick2 qt3d qtbase
sudo apt-get install qtdeclarative qtdoc qtjsbackend qtmultimedia qtquick1
sudo apt-get install qtscript qtsvg qttools qtwebkit qtxmlpatterns
</pre>

== Setting the path to qt5 ==

From a terminal
<pre>
$ export PATH=/opt/qt5/bin:$PATH
</pre>

== Compiling QtRadio ==

<pre>

cd
git clone https://github.com/alexlee188/ghpsdr3-alex.git
cd ghpsdr3-alex

sh cleanup
autoreconf -i
./configure CFLAGS='-fopenmp -O3 -msse3' CXXFLAGS='-fopenmp -O3 -msse3'
</pre>

for those of us with older machines use the line below instead:

<pre>
./configure CXXFLAGS='-O3 -msse2 -fopenmp'
</pre>
Last, build everything:

<pre>
make
sudo make install
</pre>

== Setting QtCreator to use the qt5 libraries ==

If you want to use Qt Creator (you use the same Qt Creator as with Qt4), you need to configure it to use Qt5 as one of the options:
<pre>
From the top line menu of QtCreator ...

Tools > Options > Build & Run
Click on the Qt Versions panel
Click on Add button
Navigate to /opt/qt5/bin
Click on qmake
Click on open
Click on Apply then OK
</pre>
You need to point to the qmake file which is found in /opt/qt5/bin

== Choosing the build library in QtCreator ==

you need to (re)import your QtRadio project and then you will be able to select Qt5 (or the previous Qt4.8 etc.) for building the application.

It may be necessary to edit the project file (QtRadio.pro) to choose which version of Qt Creator you are using which can be the SDK directly from Nokia, or the Ubuntu install of Creator. The line "_UsingSDK" needs to be set to true or false as appropriate.
