- Git Repository
- README
- Dttsp
- A Very good video tutorial series on using QT and C++
- A Brief Description on the architecture of ghpsdr3

- More on the Ghpsdr communications protocols (and more up to date)
- dspserver.conf The dspserver.conf file has it's own page
Most of the development discussion has been taking place on the sdr-widget google group.
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
From Synaptic Uninstall portaudio19-dev Uninstall jackd1 Install Jackd2 Install libjack-jackd2-dev Install portaudio19-dev
If you are starting from scratch
From Synaptic Install Jackd2 Install libjack-jackd2-dev Install portaudio19-dev
The following commands install all the environment needed (Debian/Ubuntu):
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
If the machine doesn't have an OpenGL aware accelerated video card, please install also the following packages:
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
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
cd svn co https://freetel.svn.sourceforge.net/svnroot/freetel/codec2-dev cd codec2-dev autoreconf -i ./configure make sudo make install sudo ldconfig
Installing Qt5
http://qt-project.org/downloads
The recommended path to install into is /opt/Qt5.0.0 (Use sudo to run the isntaller.)
Setting the path to qt5
From a terminal
$ export PATH=/opt/Qt5.0.0/5.0.0/gcc_64/bin:/opt/Qt5.0.0/Tools/QtCreator/bin:$PATH
Compiling QtRadio
cd git clone https://github.com/alexlee188/ghpsdr3-alex.git cd ghpsdr3-alex git checkout master sh ./cleanup.sh autoreconf -i ./alex-config
for those of us with older machines use the line below instead:
./configure CXXFLAGS='-O3 -msse2 -fopenmp'
Last, build everything:
make sudo make install
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:
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
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.
