More to come as we get to work on this project.
Building the main Qt4 code on Linux:
$ ./build.sh
It will create the "xastir-qt" executable in the "build" directory.
Note: You may need to edit "build.sh" for OpenSuSE Linux. Change "qmake" to "qmake-qt5".
Building the callpass executable on Linux:
$ cd callpass
$ ./build.sh
It will create the "callpass" executable in the "build" directory. Go into the build directory and type "./callpass " to get your passcode for Xastir.
