Right, sounds more or less straightforward. I googled a bit and tried some
things, and it's actually quite easy to build Gecode for iOS directly using
make. This might be easier to maintain than always having to re-import Gecode
into XCode. All you have to do is define some environment variables (maybe
adapt the paths if your installation is somewhere else):
export CFLAGS="-mno-thumb -arch armv6 -arch armv7 -isysroot
/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.3.sdk"
export CXXFLAGS=$CFLAGS
export CC=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc-4.2
export CXX=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/g++-4.2
/configure --host=arm-apple-darwin --build=i686-apple-darwin --enable-static
--disable-shared --disable-qt
When you run make, this will produce the fat static libraries for armv6/armv7.
To build the same for the simulator, you should just have to change the options
accordingly. Unfortunately, it's not that straightforward to pack the device
and simulator libraries into one three-platform lib (because lipo doesn't
understand static libraries), so you'll have to fix that manually.
We'll probably add a configure option --small-codesize or similar to enable -Os
or -Oz and use less aggressive inlining.
Cheers,
Guido
