我如何才能找到在Linux下C编程语言的头文件？ [英] How can I find the header files of the C programming language in Linux?

问题描述

当我写在Linux的C程序，然后使用gcc编译它们，我总是好奇这些头文件在哪里。例如，在 stdio.h中是。更一般地，哪里是 stdbool.h ？

When I write C programs in Linux, and then compile them using gcc, I am always curious about where those header files are. For example, where stdio.h is. More generally, where is stdbool.h?

不仅是我想知道的是它在哪里，又是如何得到那些地方，例如，使用shell命令或使用C编程语言。

What I want to know is not only where it is, but also how to get those places, for example, using shell command or using the C programming language.

推荐答案

GCC -H ... 将打印的每一个的完整路径包括文件作为一个副作用定期编制。使用 -fsyntax只除了得到它没有创建任何输出（它仍然会告诉你，如果你的程序有错误）。示例（Linux上，GCC-4.7）：

gcc -H ... will print the full path of every include file as a side-effect of regular compilation. Use -fsyntax-only in addition to get it not to create any output (it will still tell you if your program has errors). Example (Linux, gcc-4.7):

$ cat > test.c
#include <stdbool.h>
#include <stdio.h>
^D
$ gcc -H -fsyntax-only test.c
. /usr/lib/gcc/x86_64-linux-gnu/4.7/include/stdbool.h
. /usr/include/stdio.h
.. /usr/include/features.h
... /usr/include/x86_64-linux-gnu/bits/predefs.h
... /usr/include/x86_64-linux-gnu/sys/cdefs.h
.... /usr/include/x86_64-linux-gnu/bits/wordsize.h
... /usr/include/x86_64-linux-gnu/gnu/stubs.h
.... /usr/include/x86_64-linux-gnu/bits/wordsize.h
.... /usr/include/x86_64-linux-gnu/gnu/stubs-64.h
.. /usr/lib/gcc/x86_64-linux-gnu/4.7/include/stddef.h
.. /usr/include/x86_64-linux-gnu/bits/types.h
... /usr/include/x86_64-linux-gnu/bits/wordsize.h

在每行开头的点算嵌套有多深的的#include 是
