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

sudo apt-get install make gcc g++
sudo apt-get install autoconf automake autotools-dev libtool git subversion

Fedora

sudo yum install gcc gcc-c++ man-pages autoconf automake subversion libtool git

Installing prerequisite packages

Ubuntu 12.04

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:

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.

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:

$ chmod +x the-name-of-the-downloaded-file
$ sudo ./the-name-of-the-downloaded-file

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:

$ export PATH=/opt/Qt5.1.0/5.1.0/gcc_64/bin:/opt/Qt5.1.0/Tools/QtCreator/bin:$PATH

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.

qmake -v
QMake version 2.01a
Using Qt version 4.8.0 in /home/andrew/QtSDK4.8x/Desktop/Qt/4.8.0/gcc/lib

For Ubuntu 16.04, 17.10 and (maybe) Later

This will allow you to build using just Ubuntu packages, (without installing the Qt development kit it /opt as described above). At least it worked for me on an Odroid C1 running Ubuntu 16.04.1 and 17.10. First install dependencies using this:

$ sudo apt-get update; sudo apt-get install libtool autoconf portaudio19-dev libfftw3-dev libcodec2-dev libpulse-dev libusb-dev libconfig8-dev libusb-1.0-0-dev libevent-dev libevent-openssl-2.0-5 libssl-dev libortp-dev qtbase5-dev qtmultimedia5-dev libsamplerate0-dev qtdeclarative5-dev

Then test and make sure that qt5 is selected. You check that with:

$ qmake -v

If it is not version 5.something, then:

$ export QT_SELECT=qt5

Then you need to get autotools to reconfigure it:

$ autoreconf -i

Then

$ ./configure; make -j4; sudo make install

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:

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

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:

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

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

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.

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

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

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:

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

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

export LD_LIBRARY_PATH=/usr/local/lib

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

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

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

cd /usr/local/include/codec2

sudo cp * ..

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:

export LD_LIBRARY_PATH=/usr/local/lib

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.

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

Depending on your Internet connection thorughput, it will take several minute to download. cd into the new directory ghpsdr3-alex:

cd ghpsdr3-alex
git checkout master

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:

$ export PATH=/opt/qt5/bin:$PATH

Then:

autoreconf -i
./configure.sh
make -j4 all
sudo make install

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:

./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

(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)

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

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:

sudo apt-get install libboost-all-dev wget

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

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

If you already build in your sandbox some other branch, is strongly advisable, before you start the build, to do a full cleanup:

cd ~/ghpsdr3-alex
make distcheck && sh cleanup.sh

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

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

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.

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

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

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

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):

sudo apt-get install liboost-all-dev
sudo apt-get install python-cheetah

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

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

If you already build in your sandbox some other branch, is strongly advisable, before you start the build, to do a full cleanup:

cd ~/ghpsdr3-alex
make distcheck && sh cleanup.sh

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

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

Finally, you can switch to the master branch and rebuild everything, enabling the usrp server feature:

cd ~/ghpsdr3-alex
git checkout usrp-server
autoreconf -i && ./configure --enable-usrp=yes && make -j4
sudo make install

Refresh to a Newer Version

To pull a new version to build

$ git pull
$ make -j4 all
$ sudo make install

If extensive changes have occurred or if you get errors during the make, you may want to do a clean build

$ git pull
$ make distclean
$ sh cleanup.sh
$ autoreconf -i
$ ./configure
$ make -j4 all
$ sudo make install

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. 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 VirtualBox image (about 2.7 GB), unzip it, start 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 here.

If you want to edit or add the automatically started programs, see 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 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.

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.
