Xcode升级到5.1以后，以前的项目报错

Xcode升级后，之前的项目编译就报错，好像是链接错误，解决了很久都没搞定，

碰到你一样的问题，stackOverflow说是链接错误。

missing required architecture x86_64 in file /Users/zt1370/Desktop/2014-3-20 2/edooongps/EdooonGPS/libWeiboSDK.a

libWeiboSDK.a 打包链接是32bit architecture

刚去微信公众平台下载demo源码，编译正常。于是build setting->architecture->other->复制$(ARCHS_STANDARD_32_BIT)
复制内容加在自己项目target build setting->architecture

再构建应该成功了

刚把valid architectures去掉arm64 也行。

刚把valid architectures去掉arm64 他还报1个错

No architectures to compile for (ONLY_ACTIVE_ARCH=YES, active arch=x86_64, VALID_ARCHS=i386).

直接把 build setting->architecture-> 修改为NO即可

不行啊 ,还是报错!
