Location of C header files in debian
提问by James Joy
Where does debian stores C header files like stdio.h, string.hetc? I am working on a project and I need to add a header file to the location but I couldn't locate it anywhere.
debian 在哪里存储 C 头文件，例如stdio.h，string.h等等？我正在处理一个项目，我需要向该位置添加一个头文件，但我无法在任何地方找到它。

The system headers are in /usr/includeand the headers for user-installed packages are in /usr/local/include.
系统标头在 中/usr/include，用户安装的包的标头在/usr/local/include.
But you only should put headers there if you are writing a library which other projects will use. Otherwise, you should use the -Iflag for your compiler to specify the location of additional header file search paths.
但是，只有在编写其他项目将使用的库时，才应该将标题放在那里。否则，您应该使用-I编译器的标志来指定附加头文件搜索路径的位置。

Typically in /usr/include
It wouldn't hurt to run a command like this to make sure you've got the "basics" like compiler and standard headers:
apt-get install build-essentialFailing all else, you can also do a "find". For example:
find / -name stdio.h -print 2> /dev/null
通常在 /usr/include
运行这样的命令以确保您拥有诸如编译器和标准头文件之类的“基础知识”不会有什么坏处：
apt-get install build-essential如果其他方法都失败了，您还可以进行“查找”。例如：
find / -name stdio.h -print 2> /dev/null
