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

我也有类似的问题。在_OBJC_CLASS_$_后面的类名实际上是我的类。原因是我没有勾选“添加到目标”,当我拖动源代码文件到导航列表。

我的解决方案是:

从导航列表中删除类,并选择“仅删除引用” 再次拖动源代码文件,并确保“添加到目标”复选框被勾选。复选框就在“需要时复制”和“创建组”下面。

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。

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。

我只添加了libz.1.2.5。Dylib到我的项目,它的工作就像一个魅力。

步骤,

进入构建阶段。 Link Binary With library -使用“+”按钮选择要添加的框架和库。 选择libz.1.2.5。列表中的Dylib。 构建并运行。

如果你正在处理iOS5升级,我发现要编译一个目标4.3的项目,我可以将libz.1.2.3重命名。dynlib的项目导航到libz.1.2.5。Dynlib和它编译。

我的iPhoneOS50SDK/usr/lib文件夹没有libz.1.2.3。Dynlib——不知道它是测试版还是自然升级。
