c++ - g++ 使用自定义头文件编译

Question

我想使用头文件，其包含为 #include <custom.h>

如何使用 custom.h 头文件编译它？

我试过了 -I /path/to/custom.h , 但它给我的错误是它不是一个目录..

Answer 1

-I /path/to

这将能够找到该目录中的所有 header 。

在 man gcc 中，搜索(在寻呼机中使用/)“-I dir”:

-I dir

Add the directory dir to the list of directories to be searched for header files. Directories named by -I are searched before the standard system include directories. If the directory dir is a standard system include directory, the option is ignored to ensure that the default search order for system directories and the special treatment of system headers are not defeated. If dir begins with "=", then the "=" will be replaced by the sysroot prefix; see --sysroot and -isysroot.
