OpenSolaris: Compiling FFmpeg for 64-bit

Compiling the SVN version of FFmpeg for 64-bit is not difficult, but one must a little bit careful. First of all, one needs to compile x264, xvid, and libnut  among others. In all cases, one must ensure that the libraries are compiled with the -fPIC -DPIC swicthes (even SunStudio recognizes these switches). For some reason, it is necessary to produce position-independent code (PIC)  and these switches ensure this. Once these additional libraries have been installed in the proper folders (e.g., /usr/local/lib/amd64), we need to compile FFmpeg. In order to configure, I have used the following command:

CFLAGS="-m64 -I/opt/gnu/include" \
LDFLAGS="-m64 -L/opt/gnu/lib/amd64 -R/opt/gnu/lib/amd64" \
./configure --prefix=/opt/gnu --bindir=/opt/gnu/bin/amd64
--shlibdir=/opt/gnu/lib/amd64 --libdir=/opt/gnu/lib/amd64 --enable-libopencore-amrnb\
--enable-libopencore-amrwb --enable-libfaac --enable-libmp3lame  --enable-libnut \
--enable-libspeex --enable-libtheora --enable-libvorbis --enable-libx264  --enable-libxvid \
--enable-zlib --enable-bzlib  --cc=cc --enable-pic --enable-shared --enable-version3 \
--enable-gpl --enable-nonfree --enable-x11grab  --disable-mmx --enable-postproc \
--extra-cflags="-fPIC -DPIC" --enable-pthreads

Note that here cc is Sun C 5.11 SunOS_i386 Aten 2010/05/10 , that is, the latest version of the SunStudio. The configuration process generates a number of files but two of them must be modified.  First, file config.h must be modified using the following patch:

Once these steps have been taken, compilation should complete with no errors.
