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?

Go TARGETS -> General -> Deployment Info ->设置目标8.1或10.0

框架或库没有ARMV7体系结构。

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。

我在.h文件中有多个@接口,还没有包括所有相应的@实现指令。确保它们都平衡了。

如果你在你的目标>构建设置>其他链接标志下有-ObjC标志,你会遇到这个问题,考虑删除它。如果你故意添加它是因为你需要从一个静态库加载一些Obj-C代码,否则通常不会加载,IE,一个Obj-C类别,那么你应该使用-force_load <path>而不是-ObjC。

<path>应该相对于你的Xcode项目目录。IE,如果你的目录结构是这样的:

iOSProject
  + iOSAPI.framework
      + iOSAPI
  + iOSAPI.xcodeproj

然后你应该将这个标志设置为其他链接器标志:

-force_load iOSAPI.framework/iOSAPI

如果你想像这样包含多个库,那么你应该为每个库包含一个单独的-force_load行。

-force_load iOSAPI.framework/iOSAPI
-force_load another.framework/another

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.
