您会得到一个可靠的答案为您的特定设置。

同样，在 C preprocessor：

On a Unix system, where does gcc look for header files?

I spent a little time this morning looking for some system header files, so I thought this would be good information to have here.

解决方案

`gcc -print-prog-name=cc1plus` -v

This command asks gcc which C++ preprocessor it is using, and then asks that preprocessor where it looks for includes.

You will get a reliable answer for your specific setup.

Likewise, for the C preprocessor:

`gcc -print-prog-name=cc1` -v
