Updates for building on Windows CE using mingw32ce cross compiler: http://sourceforge.net/mailarchive/forum.php?thread_name 0703291652.38437.jwalt%40garni.ch&forum_name=cegcc-devel Hi! I just managed to compile SDL for Windows CE using the "mingw32ce" configuration of http://cegcc.sourceforge.net. Test programs work as expected (except for those using signals -- no POSIX on mingw32ce), and I didn't yet encounter any problem. While it was a pain to get everything compiled and running, the changes to SDL are actually quite small (see attached SDL-ce.diff). Unfortunately, the win32 headers shipped with cegcc are not 100% correct, and it feels quite messy to work around them in SDL code, so those headers will also need to be patched. (Attachment: win32api-ce.diff) Since I had to apply the libtool patch from the cegcc patch, I have also ad ded my copy of aclocal.m4 for SDL. I had to modify the cegcc libtool patch to use "lt_cv_deplibs_check_method=pass_all" for mingw32ce, otherwise libtool would not recognize the import libraries as valid for dynamic linking. All these changes should not affect non-WinCE builds, so they could be included in mainline SDL. If you need some docs, you can use this description for a cross-compilation README: 1) get cegcc from http://cegcc.sourceforge.net 2) build and install the "mingw32ce" variant (see cegcc installation docs) 3) patch w32api-headers (if not yet included in cegcc) 4) setup environment (customize the first three lines as you like): PREFIX=/opt/mingw32ce TARGET=arm-wince-mingw32ce BUILD=`uname -m`-pc-linux-gnu export PATH="$PREFIX/bin:$PREFIX/$TARGET/bin:$PREFIX/local/bin:$PATH" export CFLAGS="${CFLAGS:- -O2 -g} -I$PREFIX/local/include" export CPPFLAGS="${CPPFLAGS:- -O2 -g} -I$PREFIX/local/include" export CXXFLAGS="${CXXFLAGS:- -O2 -g} -I$PREFIX/local/include" export LDFLAGS="${LDFLAGS:- -O2 -g} -L$PREFIX/local/lib" export HOST_CC="gcc" export CC="$PREFIX/bin/$TARGET-gcc" export CXX="$PREFIX/bin/$TARGET-g++" export LD="$PREFIX/bin/$TARGET-ld" export AS="$PREFIX/bin/$TARGET-as" export AR="$PREFIX/bin/$TARGET-ar" export RANLIB="$PREFIX/bin/$TARGET-ranlib" export CONFIG_SHELL="/bin/sh" 5) build and install ./configure --target=$TARGET --host=$TARGET --build=$BUILD make make install 6) use (4) and (5) for any SDL-using software you want to cross-compile 7) copy $PREFIX/local/bin/SDL-1-2-0.dll into your executable directory on the WinCE machine
