Dne 26. 03. 19 v 15:15 Takashi Iwai napsal(a):
We used to put the additional include path $includedir/alsa in pkgconfig just because some applications have included asoundlib.h like #include <asoundlib.h> although the canonical form should be #include <alsa/asoundlib.h>
However, adding this include path is significantly dangerous due to possible conflicts of file names like version.h. It's already the reason to discourage people using alsa.pc for the packages.
In this patch, the additional include path from alsa.pc is dropped finally. At the same time, as a rescue plan for the programs including via <asoundlib.h>, a stub header file is provided in include/sound/asoundlib.h. It just includes alsa/asoundlib.h with a warning to suggest for replacing with alsa/asoundlib.h. Actually this is the same file as we install into sys/asoundlib.h, so the whole changes are very minimal here.
