Using a 32-bit library in a 64-bit app

Question

I have my project set up to run as 64-bit on supporting devices, and 32-bit otherwise. ZBarSDK is giving me an issue though. I get the error Undefined symbols for architecture x86_64 .

Doing a lipo -info on the library file results in: armv6 armv7 i386

Is there a way to still compile my project for 64-bit and include this library?

Answer 1

32位代码不能调用64位代码，反之亦然。
