So an empty > result was expected. as far as I understand the docs, the exitcode indicates whether the package can be used or not - 0 (on Fedora) is ok, 1 is bad > Try with: > [root@kwizatz firmware]# pkg-config libavcodec --libs > -lavcodecrpmfusion (yes, this is my own tweaked version, > should have been -lavcodec). well, now it gets interesting: [root@dhcp-lab-227 10]# pkg-config libavcodec --libs Package libraw1394 was not found in the pkg-config search path. Perhaps you should add the directory containing `libraw1394.pc' to the PKG_CONFIG_PATH environment variable Package 'libraw1394', required by 'libavcodec', not found and the Fedora machine: [root@F10 ~]# pkg-config libavcodec --libs -lavcodec so let's try yum install libraw1394-devel: [root@dhcp-lab-227 10]# pkg-config libavcodec --libs Package theora was not found in the pkg-config search path. Perhaps you should add the directory containing `theora.pc' to the PKG_CONFIG_PATH environment variable Package 'theora', required by 'libavcodec', not found ok, then yum install libtheora-devel: [root@dhcp-lab-227 10]# pkg-config libavcodec --libs -lavcodec [root@dhcp-lab-227 10]# pkg-config libavformat; echo $? 0 voila! - cmake can now detect ffmpeg correctly thanks for the inspiration what to try /me is going to file a bug about missing dependencies now
