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

为了它的价值,我的是固定后,我去了目标->构建阶段->链接二进制与库,删除libstdc++。TBD引用,然后添加了对libstdc++.6.0.9. TBD的引用。

其他回答

在我的例子中,我添加了一个必须使用Objective c++的框架。我找到了这个帖子:

XCode .m vs. mm

这说明了主要的。M需要重命名为main。mm,这样objective - c++类也可以被编译。

这为我解决了问题。

昨晚我遇到了一个类似的问题,这个问题与我在Xcode中从Finder拖拽一个类有关。

解决方案是选择Build Phases选项卡,然后选择Compile Sources,并确保将类拖到列表中。

我在iphone5s上运行app时遇到了这个问题,通过添加arm64到架构解决了这个问题。

在我的例子中,当我在源代码控制下创建一个新分支时,我遇到了类似的问题。

我可以通过简单地执行产品>清洁来解决这个问题

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.
