Here are the error messages:
This is missing the linker command you tried that would also help.

Hi Carl Eugen et al,
jumping on this thread as I am also current biting my nails on this
problem. I wanna redistribute ffmpeg symbols (from the static libs) with
the library I am currently working on (also LGPL).
Upon build time of my library I cannot assume that pkg-config is
available on the client machine. Hence, I need some fall-back for
catching the dependencies of all libav* and friends that I need. This is
especially tricky as I have to guess blindly what potentially these
dependencies were during build time of ffmpeg itself (aka configure
flags) and in which order they need to be linked against (I'd like to
link against the static libraries).
How to go about that in a cross-platform way?
Best,
Peter
