我在 native iOS应用程序(.a库群)中使用了第三方框架。我的应用程序是使用XCode 5基本SDK 7.0开发的。
当部署目标是6.1(库和 header 搜索路径很好)时,库可以编译并很好地链接。但是,当我将部署目标更改为7.0时,出现以下链接器错误:
Undefined symbols for architecture i386:

GetExecutionDir(ECTemplateString<char>&, char*, bool) in myLibrary.a(moPlatForm.o)

...
库有点旧,我不确定是否存在兼容性问题。我不打算支持iOS 6,因此我需要将部署目标设置为7.0。任何类型的帮助/指导都将很好。
最佳答案
对我来说,将' stdc++。6.0.9.dylib '而不是' stdc++。dylib '包含到依赖项中也解决了链接器错误
