@xqpinitial Sorry. I cannot understand your problem. Could you please clean your env, try again and provide more information?

I'm soory i did't make it clear. when i build caffe-mobile lib with cmake for Iphone,there is no problem for cmake and make -j4 however,when i start with xcode to build it by Command-R ,there is a error,Apple Mach-O Linker(Id) Error

@xqpinitial It seems like you build caffe-mobile for iPhone, but build CaffeSimple for iPhoneSimulator. Connect your iPhone to Xcode, select one of your "Devices" instead of "iOS Simulators", then Cmd+R. Have fun! ^_^

thanks for your answer,but ...i want to cry

@xqpinitial Right click on the first error, select "Reveal in log" menu. The whole log will be showed in the log message window. Normally this error is introduced by link to a libcaffe.a which is built for another architecture.

For example:

WRONG CASE1: You built CaffeSimple for iPhone, linked to a libcaffe.a(libprotobuf.a) for iPhoneSimulator:

WRONG CASE2: You built CaffeSimple for iPhoneSimulator, linked to a libcaffe.a(libprotobuf.a) for iPhone:

So please follow the instructions for different target in README.md STEP by STEP, if you don't know how to cleaning up your environment for different targets. It's really important.
