[vlc-devel] [PATCH 2/3] contribs: ffmpeg: work around the ffmpeg configure check for libmp3lame.

[Konstantin Pavlov]

On Linux, libmp3lame.a requires -lm to be linked as well.  Now this
library does not have a pkg-config file, so there are not many options
to fix it.  One option is to pass extra-libs in our contrib system, and
another one is fixing libav/ffmpeg configure to try and link libmath
during the check.  Both are not good.
