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?

当前回答

这解决了我的问题:我正在使用的依赖不支持armv7。所以我别无选择，只能把它切除。Armv7只用于非常老的iphone(比如iphone 4)。

点击“构建设置/全部” 设置“有效架构”为“arm64 arm64e”

当模块(file .m)不在我正在使用的目标中时，我常常会遇到这个问题。

目标中可能缺少一些类。这通常发生在你重命名/删除/添加新的类文件到你的项目。若要修复，请将新添加的类添加到某些目标。

在Project Navigator中选择类(右侧栏)，打开Utilities侧栏(右侧栏)，从Utilities中选择File Inspector (File like icon)，在Target Membership选项卡下勾选你的目标。这都是为了避免“删除引用”，并再次添加“添加到目标”的技巧。

所以:选择Class -> Utilities (File Inspector) -> Target Membership ->勾选你想要的目标。

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”。

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。

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.
