[FFmpeg-devel] Undefined reference to `av_free' when compiling GRASS GIS

[marco.pasetti at alice.it]

Hi list,
 
I built latest SVN snapshot of FFMPEG on MSYS/MinGW.
Here you can find detailed information on how I built it: http://www.webalice.it/marco.pasetti/temp/grass_wip/BuildFromSource.html#FFMPEG <mhtml:{3D082A7C-9377-4D29-A786-C4244C3CD99B}mid://00000103/!x-usc:http://www.webalice.it/marco.pasetti/temp/grass_wip/BuildFromSource.html#FFMPEG> 
 
Then, when I build GRASS with FFMPEG support I get the following error:
 
undefined reference to `av_free'
 
all the flags to FFMPEG libraries have been correctly set. Where could be the problem?
 
Many thanks,
 
Marco
