SDR: QtRadio Ubuntu 12.04
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 and newer
See:
http://napan.ca/ghpsdr3/index.php/Developers_Documentation
You will need qt5 to be installed as per the above. 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
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
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
cd svn co https://freetel.svn.sourceforge.net/svnroot/freetel/codec2-dev codec2-dev cd codec2-dev autoreconf -i ./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
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 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-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 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.
