Hi list,
I’ve read questions in the list archives about ffmpeg's build system
reporting that pkg-config could not find this or that external library.
I'm having the same issue: it can't find Opus, Vorbis, Theora,
mp3lame... I've tried prepending 'lib' to ".pc" file names that didn't
have that and other such tricks, but pkg-config isn't having any of it.
I've seen advice to add extra cflags and ldflags that point to the
desired libraries, but they have to be called with an '--enable-'
statement (and pkg-config has to recognize them) or they do not get
built in.
Here is the relevant portion of 'ffbuild/config.log' for Opus. Please
can some experienced person help out with this?
Jeff
