 I have a bug and workaround for grass 6.4.1 ./configure with ffmpeg on
 Slackware 13.37 x86_64

 {{{
 ./configure \
 --with-ffmpeg \
 --with-ffmpeg-includes="/usr/include/libpostproc /usr/include/libswscale
 /usr/include/libavcodec \
 /usr/include/libavdevice /usr/include/libavfilter /usr/include/libavformat
 /usr/include/libavutil" \
 --with-ffmpeg-libs="/usr/lib64"
 }}}


 I get error messages like:


 {{{
 checking whether to use FFMPEG...
 yes
 checking for location of FFMPEG includes... /usr/include/libpostproc
 /usr/include/libswscale /usr/include/libavcodec
                         /usr/include/libavdevice /usr/include/libavfilter
 /usr/include/libavformat /usr/include/libavutil

 }}}


 This happens because ./configure is looking for:
 /usr/lib64/libavcodec.so /usr/lib64/libavformat.so /usr/lib64/libavutil.so


 But on my 64bit Slackware 13.37 they are installed in:
 /usr/lib64/libavcodec64.so /usr/lib64/libavformat64.so
 /usr/lib64/libavutil64.so

 Making soft links cures the problem, but perhaps ./configure could be
 upgraded.

 {{{
 cd /usr/lib64
 ln -s libavformat64.so libavformat.so
 ln -s libavcodec64.so libavcodec.so
 ln -s libavutil64.so libavutil.so
 }}}


 I am not sure yet if I should also have created soft links for:


 '''libswscale64.so libpostproc64.so libavdevice64.so libavfilter64.so'''

 but they are not needed in order to get ./configure to run.

 Keep up the good work.
