Can't build gst-ffmpeg on MinGW

[Marko Mikkonen-2]

I have a little problem when building gst-ffmpeg-0.10.11 on MinGW. I get warning messages saying that shared libraries of avformat, avcodec and avutil are not built. Later I get a lot of linker errors about missing references to functions, all of which seem to reside in gst-libs/ext/ffmpeg subdirectories. How can I build shared libraries for avformat, avcodec and avutil? I'm not very familiar with autotools so this is a big problem for me.

These are my commands:
./configure --prefix=/c/MinGW --enable-shared --disable-static
make install

Here are the warnings and error messages:

You could try
export lt_cv_deplibs_check_method=pass_all
./configure

Important part is that the former variable should have the configure script
convince libtool to also consider a real static lib for linking, rather than
only a static import lib (with dll counterpart).
