iphone – 架构armv7的未定义符号：“_SCNetworkReachabilityCreateWithAddress”

概述对,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. Undefined symbols for architecture armv7:"_SCNetworkReachabilityCreateWithAddress", referenced from: +[Reachability reachabilityWithAddress:] in Reachabilit 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.我已经看了很多同样的问题,但很多都做了确认任何答案.这种刚刚在周末没有人碰过它的时候发展起来的.谁能帮忙.

忘了添加这个位.

ld: warning: ignoring file /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk/System/library/Frameworks//SystemConfiguration.framework/SystemConfiguration,missing required architecture armv7 in file

对@gaige感谢我发现了一个问题;在SystemConfiguration.framework之前有一个额外的斜杠,它不应该存在.我删除了框架并重新添加,但没有帮助.如何删除这个额外的斜杠？

解决方法 通常,额外的斜杠不会破坏类UNIX的构建过程.

但是,您确实需要确保armv7体系结构位于构建尝试使用的框架文件中.为此,请在命令行中使用lipo -info命令：

lipo -info /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer‌​/SDKs/iPhoneOS5.1.sdk/System/library/Frameworks//SystemConfiguration.framework/Sy‌​stemConfiguration

你应该看到这样的输出：

Architectures in the fat file: SystemConfiguration are: armv6 armv7

如果不这样做,您的项目可能已设置为链接到SystemConfiguration.framework的错误版本.您的计算机上有该框架的多个版本.因此,我将验证您在项目中的框架(即SystemConfiguration)的路径.

通常,我希望该文件是这样的(根据您正在使用的 *** 作系统版本进行调整)：

/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk/System/lib‌​rary/Frameworks/SystemConfiguration.framework
