[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
