将OSX Clang配置为包含语句区分大小写

Question

I know that case sensitivity in C++ include statements is a file system issue (related questions here and here ).

Is it possible to configure Clang to require case sensitive matches to prevent cross platform build issues?

Answer 1

Clang now has these warning flags:

-Wnonportable-include-path
-Wnonportable-system-include-path

The first is for quoted includes and the second is for angle bracket includes. They can even be mapped to errors:

-Werror=nonportable-include-path
-Werror=nonportable-system-include-path

Presumably, they're not enabled by default because they can slow down the compile. I haven't taken the time to investigate just how much.

Answer 2

Well, as you stated, and as those questions stated, it's a file system issue. If you formatted your OS X drive as case-sensitive, then it might work, but really you should probably find a different way of differentiating headers.
