If I use the command line I gave above, the final link stage command is this:
Code:
g++ -I/home/xbmc/ffmpeg-install/include -std=gnu++0x -L/home/xbmc/ffmpeg-install/lib -L/home/xbmc/ffmpeg-install/include -o comskip comskip-mpeg2dec.o comskip-comskip.o comskip-BlackFrame.o comskip-ProcessCsv.o comskip-ProcessArInfo.o comskip-LoadSettings.o -largtable2 -lavutil
You can see that this is trying the *correct* path from what I understand ("-L/home/xbmc/ffmpeg-install/lib") - the second link directive ("-L/home/xbmc/ffmpeg-install/include") is decorative, it's just there to make damned sure the linker can find the files wherever they're likely to be under ~/ffmpeg-install, even if I know they're not in "include". Taking this out makes no difference.
I just removed the whole directory to get rid of old config files, object files, etc. - untarred the source - and tried the configure command above and then make. Same problem when linking:
Code:

Manually trying the final g++ command doesn't help, no matter how much I play with options (e.g. adding the other ffmpeg libraries).
I wonder if it's an issue with how I've compiled ffmpeg - a quick squint on Google suggests that other people have had similar problems when linking dependent programs, but (sadly) for a whole variety of different reasons.
No worries, maybe someone else can take a look, the world won't end!
HNY to all, anyway.
