找不到"wchar.h"文件 [英] 'wchar.h' file not found

问题描述

我知道以下问题:​​找不到macOS'wchar.h'文件 但这并没有帮助我.我尝试过重新安装xcode，重新安装命令行工具，重新启动系统. wchar.h文件到位，但是编译器无法找到它.我还能尝试什么?也许是与sysroot相关?有什么办法解决吗?

I know about this question: macOS 'wchar.h' File Not Found but it did not help me. I've tried reinstalling xcode, reinstalling command line tools, restarting the system. wchar.h file is in place, but the compiler does not manage to find it. What else could I try? Maybe it is sysroot related? Any way to fix that?

因为wchar.h同时存在于xcode应用程序和/Library/Developer/CommandLineTools中，所以我认为它在一些完全不相关的文件夹中查找它.

since wchar.h exists both in the xcode app, and in the /Library/Developer/CommandLineTools I think that it looks for it in some completely unrelated folder.

推荐答案

我遇到了同样的问题.我可以通过使用符号链接来修复它. 这就是我做的:

I've got the same problem. I was able to fix it by using a symbolic link. This is what I made :

cd /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/
sudo ln -s MacOSX.sdk MacOSX10.07.sdk  

然后输入您的root密码.

Then enter your root password.

注意:您必须使用所需的sdk修改最后一行.

NB: you have to adapt the last line with required sdk.
