如何在Linux中添加默认的gcc路径？ [英] How to add a default include path for gcc in linux?

问题描述

除了通常的包含目录之外，我希望gcc可以从 $ HOME / include 中添加文件，但似乎并没有类似于 $ LD_LIBRARY_PATH 。我知道我可以在编译（或在makefile）中添加命令行中的include目录，但是我真的很喜欢这样一个通用的方法，就像在库中一样。

I'd like gcc to include files from $HOME/include in addition to the usual include directories, but there doesn't seem to be an analogue to $LD_LIBRARY_PATH. I know I can just add the include directory at command line when compiling (or in the makefile), but I'd really like a universal approach here, as in the library case.

推荐答案

尝试设置 C_INCLUDE_PATH （C头文件）或 CPLUS_INCLUDE_PATH （C ++头文件）。

Try setting C_INCLUDE_PATH (for C header files) or CPLUS_INCLUDE_PATH (for C++ header files).

由于Ciro提到， CPATH 将为C和C ++设置路径。

As Ciro mentioned, CPATH will set the path for both C and C++.
