Hi,
I have no idea, though, why the compiler does this. Maybe because the
.c header is explicitely included. Changing <boost/assert.hpp> to
include <cassert> instead of <assert.h>, as discussed in the code
comment, should fix the issue as well. I have yet not tried this out,
though. - Fabian
I tried to change #include <assert.h> to #include <cassert> but it
didn't work.
I use FLAC++ in project and FLAC++ requires FLAC. So I think it is very
necessary to add FLAC search directory path to gcc flags.
But, if i would use only FLAC I could add only #include <FLAC/decoder.h>
to source files, so additional search path would be not necessary.
GCC first looking for header files in user specified search paths.

--cflags flac` --verbose
