问题描述

I am trying to "arm" compile a C file,it includes lot of header files recursively..i am trying to find the list of these header files..is there a easier way to find the list of all the header files it includes?

推荐答案

您可以使用GCCÇpreprocessor与它的选项转储递归包括标题的列表：

You can use the GCC C preprocessor with it's option to dump a list of headers recursively included:

cpp -M

这会告诉你所有的标题包括在内。

That will show you all headers included.

您可能会需要给它的根源都包括常规构建使用的目录。运行反复，增加更多的包含路径，直到错误停止。

You will probably need to give it the roots of all include directories used in your regular build. Run it iteratively, adding more include paths until the errors stop.

该命令的这种用法的完整形式是：

The full form of this command in this usage is:

cpp -M [-I include_directory *] path_to_c_file.c
