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
