We will create a minimal static universal OpenCV library with 3 architectures: Intel, PowerPC and Arm for the iPhone. I've been testing it on Leopard but it should work on any Mac OS X version.

First checkout or untar the OpenCV sources in the opencv directory. Then, on the same level (not inside) create a build directory with 3 subdirectories: ppc, i686 and armv6. (Download the code from Sourceforge)

Then set the global configure settings:

$ export CONFFLAGS="--without-imageio --without-python --without-swig --disable-apps --disable-dependency-tracking --without-carbon --without-quicktime --enable-shared=no --without-gtk"

in the ppc dir:

$ ../../opencv/configure ${CONFFLAGS} --host=ppc-apple-darwin9
$ make CXXFLAGS="-arch ppc"

in the i686 dir:

$ ../../opencv/configure ${CONFFLAGS} --host=i686-apple-darwin9
$ make CXXFLAGS="-arch i686"

in the arm dir:

$ ../../opencv/configure ${CONFFLAGS} --host=arm-apple-darwin9 CXX=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/arm-apple-darwin9-g++-4.0.1 CXXFLAGS="-arch armv6 -isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.0.sdk" CXXCPP=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/cpp
$ make

the last one is tough, so let's see the variables one by one:

CXX=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/arm-apple-darwin9-g++-4.0.1
CXXFLAGS="-arch armv6 -isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.0.sdk"
CXXCPP=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/cpp

Ok. Now for the universal static libs:

$ lipo -create i686/cv/src/.libs/libcv.a ppc/cv/src/.libs/libcv.a armv6/cv/src/.libs/libcv.a -output libcv.a
$ lipo -create i686/cxcore/src/.libs/libcxcore.a ppc/cxcore/src/.libs/libcxcore.a armv6/cxcore/src/.libs/libcxcore.a -output libcxcore.a
$ lipo -create i686/cvaux/src/.libs/libcvaux.a ppc/cvaux/src/.libs/libcvaux.a armv6/cvaux/src/.libs/libcvaux.a -output libcvaux.a
$ lipo -create i686/ml/src/.libs/libml.a ppc/ml/src/.libs/libml.a armv6/ml/src/.libs/libml.a -output libml.a
$ lipo -create i686/otherlibs/highgui/.libs/libhighgui.a ppc/otherlibs/highgui/.libs/libhighgui.a armv6/otherlibs/highgui/.libs/libhighgui.a -output libhighgui.a

That's all. Oh, try
$ make -j 2
