架构armv7未定义的符号

这个问题快把我逼疯了，我不知道怎么解决它。

    Undefined symbols for architecture armv7:
  "_deflateEnd", referenced from:
      -[ASIDataCompressor closeStream] in ASIDataCompressor.o
  "_OBJC_CLASS_$_ASIDataDecompressor", referenced from:
      objc-class-ref in ASIHTTPRequest.o
  "_deflate", referenced from:
      -[ASIDataCompressor compressBytes:length:error:shouldFinish:] in ASIDataCompressor.o
  "_deflateInit2_", referenced from:
      -[ASIDataCompressor setupStream] in ASIDataCompressor.o
ld: symbol(s) not found for architecture armv7
collect2: ld returned 1 exit status
Command /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc-4.2 failed with exit code 1

我认为这与:

ld: symbol(s) not found for architecture armv7

但是我添加了:libz.1.2.3。Dylib并没有帮助，有人有什么想法吗?

If you're building from Unity3D 5 and also using a Prime31 plugin and you're getting this error it's probably due to a duplicate .dll. If you look through your warnings in Unity's editor one of them will tell you this and warn that it could cause build errors. To see if this is the case, type P31 in your project search field and it should pop right up, maybe even more than one. The duplicate's will have a ' 1' at the end of the file name. This is probably caused from updating the plugin in editor via the store or the Prime31 menu tab.

回到你的项目，点击Build phases, Compile sources, Add GameCenterManager。M到列表上。

最后我想明白了，我通过添加缺少框架的目标->构建阶段->链接二进制库解决了这个问题

另一个可能导致“未定义符号”链接错误的原因是试图从.mm文件调用C函数。在这种情况下，您需要使用extern“C”{…}当您导入头文件时。

从objective - c++调用C-Function链接器错误

我遇到了类似的问题，我必须在每个项目配置(调试、发布和部署)和目标的构建设置中检查“仅构建活动体系结构”。

当我加入第三方框架时，我也遇到了同样的问题。
