Compile C lib for iPhone

Question

I\'m trying to compile ZeroMQ C binding in order to be able to use it on iPhone, here is my configure options:

./configure --host=arm-apple-darwin --enable-st

Answer 1

It sounds like you're building a universal armv6/armv7 binary for the iPhone (this is the default, so that makes sense). That means that you need to build a universal library to link against. Build both libraries, and then use lipo to combine the two.

For example, build the armv6 one and place it at armv6/libfoo.a, and the armv7 one at armv7/libfoo.a. Then run

lipo -arch armv6 armv6/libfoo.a -arch armv7 armv7/libfoo.a -output libfoo.a -create

to create the universal library libfoo.a.
