[x264-devel] Failing to load shared library libffms2.so.0

[Sean McGovern]

Is it possible the copy in /usr/local/lib is corrupt or the wrong architecture (i386 vs. x86_64)?

Subject: [x264-devel] Failing to load shared library libffms2.so.0

Hello,

I'm having problems with x264-linking (again). I just updated
ffmpegsource and noticed they changed their libname to lowercase.
Allright, so i patched x264 to use it (since it did not recognize it yet):

Configuring works well, linking with "-lffms2" too.

gcc -o x264 x264.o [...] -lm -lpthread -Wl,-Bsymbolic -s -L. -lavformat
-lswscale -lpostproc -lavcodec -lavutil -lm -lz -lbz2 -lpthread -lffms2
-lgpac_static



 but...:

What am I missing? Note I did not try to compile x264 with the patches
starting with 6662db34 and old ffmpegsource, so might be a problem with
these changes... (but had it running with old ffmpegsource and before
6662db34)
