这个问题一直让我发疯,我无法解决如何修复它...

我认为这与:

ld: symbol(s) not found for architecture armv7

但我补充道:libz.1.2.3.dylib它没有帮助,任何人都有任何想法？

我目前是Objective C的真正初学者,我正在使用框架OpenCV开发一个应用程序.

我正在学习一个教程,但在构建项目时,我遇到了几个错误:

我试图在xcode 4.2.1下使用XMPPFramework和iOS5项目(ARC),但我遇到了这个问题.有一次,我添加CocoaAsyncSocket到我的项目的准备我的项目使用XMPPFramework如在部分1我碰到下面的错误.

我见过其他一些人有"未定义的架构armv7符号",但我目前还没有找到这个问题的答案.

我已链接到CFNetwork并将GCDAsyncSocket.m标记为非ARC(-fno-objc-arc)但我仍然收到错误.任何帮助表示赞赏.

对,这已成为一种正确的痛苦我现在已经看了2天,似乎无法解决它.这是我得到的错误.

我添加了SystemConfiguration.framework,它似乎不想对它做任何事情,因为这个错误不会消失.我已经看了很多相同的问题,但很多都做了确认任何答案.这种刚刚在周末没有人接触它的时候发展起来的.谁能帮忙.

编辑 忘了添加这个位.

ld:警告:忽略文件/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk/System/Library/Frameworks//SystemConfiguration.framework/SystemConfiguration,缺少必需的架构armv7在文件中

我已经阅读了很多关于SO的帖子,并且所提出的解决方案都没有为我工作.我希望那些对解释错误有更多了解的人可以提供帮助.

我的应用程序一直运行良好(现在仍然如此),但是当使用某个类'iCarousel'时,我遇到了一个问题,这是一个Cover Flow的实现.

这是有趣的事情:当打开iCarousel的示例项目时,它在我的iPhone上正常运行.我的应用程序(在一个单独的项目中)也运行良好.他们都使用armv6 armv7 架构并在iOS 5.1上运行.

然后我将类复制到我自己的项目并添加所有必要的框架.还没有错误.但是当我构建并运行时,我收到一个错误:

在此之下:

Undefined symbols for architecture armv7:
  "_OBJC_CLASS_$_ArtworkScrollerViewController", …

我只是将所有CocoaAsyncSocket代码标记为非ARC代码,并且它给了我这3个错误:

  "_kCFStreamNetworkServiceTypeVoIP", referenced from:
      -[GCDAsyncSocket enableBackgroundingOnSocketWithCaveat:] in GCDAsyncSocket.o

      -[GCDAsyncSocket maybeStartTLS] in GCDAsyncSocket.o
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

有谁知道这意味着什么以及如何解决它？

我导入了RNCryptor,可以在这里找到:https://github.com/rnapier/RNCryptor到我的应用程序中.但是,我在日志中遇到了三个错误.

Undefined symbols for architecture armv7:
  "_SecRandomCopyBytes", referenced from:

ld: symbol(s) not found for architecture armv7

我看到这通常是在导入的类没有包含在目标中时引起的,但是我已经检查了构建阶段,并且所有导入的类都在那里.我不知道造成这种情况的原因,我没有触及任何这些类的代码.我还清理了几次目标.

我正在尝试在同一个项目中使用ZXing和OpenCV.你不会认为这是罕见的事情,但我想是的.我在两者之间存在一些严重的兼容性问题.我只能在没有另一个的情况下进口一个.

我从OpenCV开始,一切正常.程序按预期运行.然后我添加了ZXing,我得到了大约27个编译器错误.有一个stackoverflow问题在这里解决这个问题.因此,我更改了我的C++编译器设置以匹配此问题所暗示的内容,并修复了ZXing问题,但随后又打开了一组全新的错误.这些错误现在与OpenCV有关(见下文).

编辑:
似乎取决于C++编译器,它是一个或另一种类型的交易.实际上,如果将c ++标准库从libc ++更改为libstdc ++,您将获得一个工作而不是另一个工作.我无法同时看到两者同时获得
