This document describes how to build the FreeDV GUI program for various operating systems. FreeDV GUI is developed on Ubuntu Linux, and then cross compiled for Windows using Fedora Linux (Fedora has great cross compiling support) and Docker.

$ sudo apt install libc6-i386 libspeexdsp-dev libsamplerate0-dev sox git \
libwxgtk3.0-dev portaudio19-dev libhamlib-dev libasound2-dev libao-dev \
libgsm1-dev libsndfile-dev cmake
$ git clone https://github.com/drowe67/freedv-gui.git
$ cd freedv-gui
$ ./build_linux.sh
Then run with:
$ ./build_linux/src/freedv
Note this build all libraries locally, nothing is installed on your machine. make install is not required.
$ sudo dnf groupinstall "Development Tools"
$ sudo dnf install cmake wxGTK3-devel portaudio-devel libsamplerate-devel \
libsndfile-devel speexdsp-devel hamlib-devel alsa-lib-devel libao-devel \
gsm-devel
$ git clone https://github.com/drowe67/freedv-gui.git
$ cd freedv-gui
$ ./build_linux.sh
Then run with:
$ ./build_linux/src/freedv
The wav directory contains test files of modulated audio that you can use to test FreeDV (see the USER_MANUAL)
The Windows build process above has been automated using a Docker container, see the freedv-gui Docker README
Install basic MinGW development packages:
$ sudo dnf install mingw{32,64}-filesystem mingw{32,64}-binutils \
mingw{32,64}-gcc mingw{32,64}-crt mingw{32,64}-headers mingw32-nsis
Install dependencies of FreeDV/Codec2:
$ sudo dnf install mingw{32,64}-speex
Enable Freetel specific packages not currently in Fedora proper:
$ sudo dnf install dnf-plugins-core
$ sudo dnf copr enable hobbes1069/mingw
$ sudo dnf install mingw{32,64}-wxWidgets3 mingw{32,64}-hamlib \
mingw{32,64}-portaudio mingw{32,64}-libsndfile mingw{32,64}-libsamplerate.noarch
Clone freedv-gui:
$ cd
$ git clone https://github.com/drowe67/freedv-gui.git
Building FreeDV for 64 Bit windows:
$ cd ~/freedv-gui
$ ./build_windows.sh
$ cd build_win64
$ make package
OR Building FreeDV for 32 Bit windows:
$ cd ~/freedv-gui
$ CMAKE=mingw32-cmake ./build_windows.sh
$ cd build_win32
$ make package
Conveniently, it is possible to run Windows executables using Wine on Fedora:
Testing LPCNet:
$ cd ~/freedv-gui/LPCNet/build_win/src
$ WINEPATH=$HOME/freedv-gui/codec2/build_win/src';'$HOME/freedv-gui/build_win/_CPack_Packages/win64/NSIS/FreeDV-1.4.0-devel-win64/bin/ wine lpcnet_enc.exe --infile all.wav --outfile all.bit
$ WINEPATH=$HOME/freedv-gui/codec2/build_win/src';'$HOME/freedv-gui/build_win/_CPack_Packages/win64/NSIS/FreeDV-1.4.0-devel-win64/bin/ wine lpcnet_dec.exe --infile all.bin --outfile all_out.raw
$ cat all_out.raw | aplay -f S16_LE -r 16000
Testing FreeDV API:
$ cd freedv-gui/codec2/build_win/src
$ WINEPATH=$HOME/freedv-gui/LPCNet/build_win/src';'$HOME/freedv-gui/build_win/_CPack_Packages/win64/NSIS/FreeDV-1.4.0-devel-win64/bin/ wine freedv_rx 2020 ~/freedv-gui/wav/all_2020.wav out.raw
$ play -t .s16 -r 16000 -b 16 out.raw
Please see README.osx
In build_linux.sh change the build_linux directory to build_freebsd
