Ah, OK, thanks.

Now I'm using this:

export PATH=$(pwd)"/usr/bin:$PATH"
tools/make-shared-from-static --windowsdll --ar
x86_64-w64-mingw32.static-ar --ld x86_64-w64-mingw32.static-ld
--libdir usr/x86_64-w64-mingw32.static/lib --bindir
usr/x86_64-w64-mingw32.static/bin
usr/x86_64-w64-mingw32.static/lib/libsndfile.a

... and I get this output:

This looks a bit strange, because of the "-Wl," stuff, which should be
removed before passing the options to the linker (as far as I know).
If I remove them manually, however, I get more errors because the
o-files cannot be found:

x86_64-w64-mingw32.static-ld: cannot find add.o: No such file or directory
x86_64-w64-mingw32.static-ld: cannot find aiff.o: No such file or directory

Do I have to use --install?
If yes, how exactly?

What else am I missing?

cheers,
Matthias
