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?


当前回答

当我加入第三方框架时,我也遇到了同样的问题。

当我从目标的构建设置中的有效架构条目中删除armv7s时,问题得到了解决,它开始工作。

其他回答

当我使用admob库时,我也有同样的问题,我修复了它将“架构”更改为“标准架构armv7, armv7s”,而不包括64位。

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”。

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

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.

将m文件(包括funcs方法)重命名为mm,反之亦然。 我的解决了将mm重命名为m 或者m到mm。
