This library is an attempt to package wsjtx fortran code into a c++ callable library It is intended for implementation in SDR tranceivers running in linux (raspberry pi) The library can be build, on linux, by downloading and building the cmake file.

To use the library dowload git repo, there is an dependency to cmake, gfortran, and fftw3

sudo apt install cmake g++
sudo apt install gfortran
sudo apt install libfftw3-3
sudo apt install libfftw3-dev
sudo apt install libboost-all-dev

git clone the repo
cd wsjtx_lib
mkdir build
cd build
cmake ..
make
sudo make install

To use the library

#include <wsjtx_lib.h>

add to the linker -l"wsjtx_lib" -l"pthread" -l"fftw3f" -l"fftw3f_threads" -l"gfortran"

Create wsjtx_lib class and use the methods
Sample wav files are part of the original wsjtx download
