MSYS2 is simple to install, it uses a win32 port to install packages that is what I use to compile ffmpeg (among other libs). ffmpeg is also compiled and available with pacman : https://packages.msys2.org/package/mingw-w64-x86_64-ffmpeg > I suspect the "ffmpeg docs" (not sure what exactly you mean with it) were > written before wsl existed. > > But given our exchange so far, I wasn't extremely surprised that you > did not want to follow what I suggested. > > If you absolutely want to cross-compile from a Linux box for Windows, > this also works fine but I always only saw disadvantages.

So the former apparently fails. ah, at least it seems that indeed pkg-config fails to find the pc file Note that PKG_CONFIG_PATH is not set and i do instead (see https://autotools.io/pkgconfig/cross-compiling.html section 4.4 at the bottom) : export PKG_CONFIG_DIR= export PKG_CONFIG_LIBDIR=$HOME/ffmpeg/lib/pkgconfig export PKG_CONFIG_SYSROOOT_DIR=$HOME/ffmpeg (it's in my ffmpeg.sh attached in my original mail) > I could tell easier if I was on your system. ;-) you can : just run ewpi :D but it is a bit long to get to ffmpeg. compilation thank you Vincent Torri ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".

Perhaps you should add the directory containing `foo.pc' to the PKG_CONFIG_PATH environment variable No package 'foo' found if libbluray.pc is not found, is it normal that config.log has no such message ?
