BUG: compile error with ffmpeg + solution

i get an compile error with ffmpeg after "make" [Linking Motion...] i tracked down the problem to the Makefile line 37:

"LIBS = -lm -lpthread -ljpeg -L/usr/local/lib -lavformat -lavcodec -lm -lz -L/usr/lib -lmysqlclient -lz $(CC) $(LDFLAGS) -o $@ $(OBJ) $(LIBS)"

and changed it to:

"LIBS = -lm -lpthread -ljpeg -L/usr/local/lib -lavcodec -lavformat -lavutil -lm -lz -L/usr/lib -lmysqlclient -lz $(CC) $(LDFLAGS) -o $@ $(OBJ) $(LIBS)"

and it compiled just fine ...

i realy dnt know is the problem svn-ffmpeg or a paticular compiler ... never less it was a big step for me but a small one for human kind... kind regards knatterton

Follow up

I can't reproduce that problem on debian either ubuntu , but i think that is because those distros have ffmpeg-config that helps to get libs and includes.

What distribution are you using ?

How did you compile ffmpeg ?

I've compiled svn trunk :

./configure --enable-shared
make 
make install

After compiled motion with ffmpeg support without any problem.

 /usr/local/bin/ffmpeg -version
