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 command install all the environment needed:
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
If the machine doesn't have an OpenGL aware 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
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 cd codec2 autoreconf -i ./configure make sudo make install sudo ldconfig
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 ...
sudo add-apt-repository ppa:canonical-qt5-edgers/qt5-daily
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:
sudo apt-get update
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 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 ...
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
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:
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
Setting the path to qt5
From a terminal
$ export PATH=/opt/qt5/bin:$PATH
Compiling QtRadio
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'
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/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/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.
