Hi there,

Current git head.

./configure --disable-shared --enable-static --extra-version=static 
--extra-cflags='--static -I/usr/local/include' --extra-libs='-static 
-L/usr/local/lib' --prefix=/usr/local --disable-ffplay --enable-pthreads 

fails, with this as the error:

plus hundreds of other errors.

I only have static libs built for orc and schroedinger, so at line 3123 
in configure the call to `require_pkg_config()` which then calls 
`check_pkg_config()` which eventually calls `pkg-config --libs 
schroedinger-1.0` but does not include --static, which is needed for a 
static build.

With the attached patch I can configure and make ffmpeg as a static. But 
I'm sure that is not a good idea, really. I hoped I was missing a 
configure switch, but I haven't seen anything.

Now, perhaps I'm wrong in trying to make a static, as this warning suggests:

LD	ffmpeg_g
libavformat/libavformat.a(rtsp.o): In function `get_sockaddr':
/home/himslm01/src/ffmpeg/libavformat/rtsp.c:160: warning: Using 
'getaddrinfo' in statically linked applications requires at runtime the 
shared libraries from the glibc version used for linking

Perhaps I should try to gather all the libs I include and set 
LD_LIBRARY_PATH - but that's a lot more of a faff than making a static 

I hope I can get some feedback from the good people on this list.
