[LMMS-devel] lmms on OpenBSD

[Jacob M. <ja...@sd...>]

hi,

cool project :)

I got lmms-0.8.4 working on OpenBSD/i386 with some simple patches.

I will give an explanation of them.  I don't understand cmake well,
so I probably was just hacking.  maybe you can suggest a good method?

CMakeLists.txt:

  added -lossaudio to LINK_LIBRARIES be able to use the OSS emulation
  on OpenBSD.  this should probably have some kind of test I suppose?  what
  would be the preferred way and where?

  added -Wl,-E to lmms link flags by adding the following line:
  SET_TARGET_PROPERTIES(lmms PROPERTIES LINK_FLAGS "${LINK_FLAGS} -Wl,-E")
  without this, most plugins would complain of unresolved symbols.  the
  symbols that lmms provides, to be more exact.


include/remote_plugin.h:

  for some reason the tests for sys/ipc.h and sys/shm.h failed.  how
  do I see why they failed?

  also had to include unistd.h or usleep() was not defined.


src/core/audio/audio_oss.cpp:

  g++ complained about
  #elif LMMS_HAVE_SOUNDCARD_H
  I changed it to
  #elif defined(LMMS_HAVE_SOUNDCARD_H)


src/core/main.cpp:

  had to include unistd.h or getpid() was not defined.
  also OpenBSD's pthreads doesn't support sched_get_priority_{max,min},
  so I added #ifndef __OpenBSD__ after #ifdef LMMS_HAVE_SCHED_H around
  line 345.
