missing required architecture i386 in file

问题描述:今天研究QCAR的iPhone版本,下载Demo后编译报错,如下:

ld: warning: ignoring file ../../build/lib/arm/libQCAR.a, missing required architecture i386 in file

ld: symbol(s) not found for architecture i386

clang: error: linker command failed with exit code 1 (use -v to see invocation)

问题分析:开始以为是没有找到库,重新引用库,无效。后查Google,要删除掉Targets-Build Settings-Library Search Paths,照做,无效。最后找到以下这段:

It seems the library is built for phone deployment (ARM) but you are trying to link it to a simulator executable (x86). This won’t work. Rebuild the library for the simulator.

问题解决:切换成Device编译,搞定。
