[FFmpeg-devel] check Libraries before compiling!?

[Ramon Hackbarth]

Hello Developers,

yesterday I compiled ffmpeg with AAC decoders, everything worked
fine I thought, but AAC decoders didn't work even they were
compiled and - I thought - also working. It was the newest FAAD
Library which depends on a newer libc6 version, which wasn't
installed. I installed a newer libc6 version (and libfaad 2.6), but
afterwards I had some problems and reinstalled the old version of
libc6, but I left libfaad 2.6 (which doesn't work without newest
libc6).
Is it maybe possible to include a function which checks also if the
library is working and not just if it's existing?

Best Regards
raha
