如何包括自定义.h文件在/ usr / include目录 [英] How to include custom .h files in /usr/include

问题描述

我在/ usr / include目录，但在目录（/ usr / include目录/ itsmag1c）放置一些自定义的.h文件，我试图将它们纳入我的C文件。我猜是因为我用

I have some custom .h files placed under /usr/include, but in a directory (/usr/include/itsmag1c), and I'm trying to include them in my C file. I'm guessing that because I use

#include "filename.h";

在同一目录下的文件，我会用尖括号用于包括像math.h中或stdio.h中的文件。我是正确的猜测，我会用尖括号的包括我的自定义头文件？如果是这样，我的程序不会编译，我得到了包括文件无法找到的错误。可有人请指向我，我怎么会包含这些文件，或者这将是最好让他们在同一目录作为我的计划？

for files in the same directory, and I would use angle brackets for including a file like math.h or stdio.h. Am I right in guessing that I would use the angle brackets for including my custom header files? If so, my program wont compile, I get the error that the included files cannot be found. Can someone please point to me how I would include these files, or would it be best to have them in the same directory as my program?

推荐答案

两种选择：

1. 使用的#include＆LT; itsmagic1c / filename.h＆GT;

使用的#include＆LT; filename.h＆GT; 和以前一样，但添加 -I 开关。

Use #include <filename.h> as before but add a -I switch.

升压等使用方法1（效果很好如果已经安装在系统中的位置提升，因为你会在一个合理的标准Linux主机，并合理的方案管理）。

Boost etc use method 1. (which works well provided you have Boost installed in system locations as you would on a reasonably standard Linux box with reasonable package management).

方法2是好的太多，但构建系统​​，Makefile文件等更多的工作。

Method 2. is fine too, but more work on the build system, Makefiles, etc.
