将Objective-C应用程序链接到C++静态库
dre*_*wag 8 c++ xcode linker clang static-libraries
我正在尝试使用Xcode构建一个链接静态C++库的Objective-C桌面应用程序.我正在使用Apple的clang编译器.我收到以下链接器错误:
Apple clang version 3.0 (tags/Apple/clang-211.12) (based on LLVM 3.0svn)

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
好像它没有链接到C++ std库.这是问题所在,如果是这样,我如何确保它与之相关联？
更新:
如果我向构建添加一个空白的cpp文件,那么一切都编译并运行正常.我似乎只需要一种方法告诉链接器链接到C++ std库.我试过查看Xcode中的所有构建设置,但似乎找不到任何有用的东西.
