Compile without audio #1356

Open xaratustrah opened 3 months ago

xaratustrah commented 3 months ago

If audio is not needed, I was wondering if it is possible to compile gqrx without audio support? Maybe similar to https://github.com/gqrx-sdr/gqrx/issues/258#issuecomment-167447953 by passing an argument to cmake but this time in order to turn off all audio dependencies / features?

I did the cmake approach, see here: https://github.com/kgarrels/gqrx/commit/a06c6360347ef6253337c8efa09adb67b1e99434?diff=split&w=0

Thanks. I just cloned your version from here, in the build directory I run::

cmake -DLINUX_AUDIO_BACKEND=Null-audio ..

I still get:

CMake Error at CMakeLists.txt:198 (message):
  Invalid audio backend: should be either Pulseaudio, Portaudio, Null-audio,
  or Gr-audio

maybe I should invoke it differently?

I implemented this only for Darwin (macos). I tried to fix it, but I cannot currently test it.

Please pull and try again.

PS: my fork has many other changes vs. master , maybe you should try to just apply that commit to master
