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

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。

其他回答

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。

常见的原因

导致“架构armv7中未定义的符号”的常见原因有:

You import a header and do not link against the correct library. This is common, especially for headers for libraries like QuartzCore since it is not included in projects by default. To resolve: Add the correct libraries in the Link Binary With Libraries section of the Build Phases. If you want to add a library outside of the default search path you can include the path in the Library Search Paths value in the Build Settings and add -l{library_name_without_lib_and_suffix} (eg. for libz.a use -lz) to the Other Linker Flags section of Build Settings. You copy files into your project but forgot to check the target to add the files to. To resolve: Open the Build Phases for the correct target, expand Compile Sources and add the missing .m files. If this is your issue please upvote Cortex's answer below as well. You include a static library that is built for another architecture like i386, the simulator on your host machine. To resolve: If you have multiple library files from your libraries vendor to include in the project you need to include the one for the simulator (i386) and the one for the device (armv7 for example). Optionally, you could create a fat static library that contains both architectures.

最初的回答:

您没有链接到正确的libz文件。如果你右键点击该文件并在finder中显示它的路径应该在iOS sdk文件夹中的某个地方。这是我的例子

/开发/平台/ iPhoneOS.platform /开发/ sdk / iPhoneOS4.3.sdk / usr / lib

我建议删除引用，然后在目标的构建阶段Link Binary With Libraries部分重新添加它。

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。

下面是我是如何得到这个问题的:

我从另一个项目中添加了.h， .m和NIB，把它们拖到我的项目导航器上。Xcode没有正确地将它们添加到构建阶段。

检查我的答案，因为我有一个类似的问题，我可以通过做一些步骤来解决。
