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

如果您在释放模式下构建您的Flutter项目时遇到了这个问题-这对我有帮助:

Set your build system to New Build System in File > Project Settings… delete folders ios and build_ios from your project folder. create ios module by executing flutter create . from your project folder. open Xcode and: set the IOS Deployment Target to at least 9.0 in PROJECT > Runner check your Signing & Capabilities make sure your Build Configuration is set to Release in Edit Scheme... and build for Generic iOS Device execute pod install from your project folder execute flutter pub get from your project folder

现在打开你的Xcode并构建或存档它:Product > build(或archive)

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。

别名通常不包含链接到当前版本的版本标识符，在本例中为libz。Dylib链接到libz.1.2.5.dylib。使用基本别名，而不是版本化的别名。

尝试实现派生类的至少一个非内联函数。如果不这样做，链接器可能会避免为该类创建类型信息。

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。
