For iOS using XCode ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ -To cross compile for iOS, configure with:: +For iOS, you typically build for 3 architectures: armv7 (32 bit, older iOS devices), armv8-a (64 bit, recent iOS devices) and x86_64 for the iPhone simulator. You can build for these 3 architectures and then create a universal binary containing code for all of these architectures, so you can link to Botan for the simulator as well as for an iOS device. - $ ./configure.py --cpu=armv7 --cc=clang --cc-abi-flags="-arch armv7 -arch armv7s -stdlib=libc++ --sysroot=$(IOS_SYSROOT)" +To cross compile for armv7, configure and make with:: -Along with any additional configuration arguments.
