The released binary works, so I've got enough of pulseaudio or jack or alsa or whatever is technically required.
My build of FreeFileSync on Fedora works with audio. I can even tell that it is linked to libsdl2:
[bgstack15@desktop2|/home/bgstack15]$ ldd /usr/bin/FreeFileSync | grep -i sdl libSDL2-2.0.so.0 => /lib64/libSDL2-2.0.so.0 (0x00007f67c9972000)
I don't really know what I'm doing here. Could this perhaps be related to how Debian builds wxWidgets? Maybe it is not linked to libsdl as I expect?
Does anyone else here compile for Debian, or can anybody point me in a direction?
