I'm trying to build a set of static SDL_* libraries in my Mingw cross-compilation setup on Mac OS X. I have only static (no dynamic) versions of libpng and libtiff installed and configure SDL_image using cross-configure.sh --prefix=/usr/local/cross-tools/i386-mingw32 --disable-shared --disable-jpg-shared --disable-png-shared --disable-tif-shared In this invocation, the checks for libpng and libtiff fail (even though the libraries are there, and are found) because of missing symbols from zlib. I can fix this using the attached patch. I assume this shouldn't interfere in the case that dynamic png/tiff libraries are around, but I'm reluctant to try it, and I'm not very familiar with autoconf in general. Perhaps someone who is can advise if this is the right thing to do...
