Linux下C语言编程环境的工具

要想在Linux下进行C语言编程，首先得搭建好一个编程环境。这里分别说明一下几个非常有用的软件包。
如果你对Linux下软件安装方法还不清楚，请参考文章“Linux下软件安装方法总结”http://zhoulifa.bokee.com/5444771.html
1、gcc
要进行C语言编程，首先得有个C语言的编译器，Linux下常用的是GNU C Compiler gcc。软件包的信息如下：
Package: gcc
Priority: optional
Section: devel
Installed-Size: 64
Maintainer: Ubuntu Core Developers <[e-mail]>
Original-Maintainer: Debian GCC Maintainers <[e-mail]>

我们从上面可以看出这个gcc软件是用来提供默认值的。从Depends可以看出要gcc真正工作必须有对应的cpp和gcc版本。
比如cpp-4.1和gcc-4.1、cpp-3.3和gcc-3.4

2、gcc-*
这里以gcc-4.1版本为例，该软件包信息如下：
Package: gcc-4.1
Priority: optional
Section: devel

3、cpp
gcc要进行程序编译，首先需要进行一个预编译过程。该过程对程序源代码进行预处理。
cpp软件包的信息如下：
Package: cpp

6、libc6
C语言程序要能够运行，需要一些运行时库文件和一些库文件操作命令。libc6这个软件包就是用来提供这些的。这个软件包几乎是Linux系统自带的，因为所有C程序的运行都离不开此软件包。软件包信息如下：
Package: libc6
Priority: required

这个软件包提供下面这些非常有用的命令：
/usr/bin/size # 显示每个目标文件或归档文件的章节大小和总的大小
/usr/bin/objdump # 显示目标文件的信息
/usr/bin/ar # 归档文件管理工具，可以创建、修改或打开一个归档文件

虽然上面列了这么多必需的软件包，但实际上因为他们之间有依赖关系，所以在安装完系统后我们只需要输入下面一个命令：
apt-get install gcc
系统就会自动帮忙把这些软件包安装上。

9、libc6-dev
我们要进行软件开发，必然需要一些库文件和头文件，在Linux常用的就是GNU的C语言库libc，要安装开发工具必须安装这个libc6-dev软件包，信息如下：
Package: libc6-dev
Priority: optional

10、glibc-doc
进行C语言开发过程中必须遇到一些问题需要参考一下GNU的文档，一种方法当然是去gnu.org，但如果上不了网呢？就最好把这个软件包glibc-doc安装上，此软件包信息如下：
Package: glibc-doc
Priority: optional
Section: doc
Installed-Size: 1980

ChangeLog. The GNU C Library Reference manual has been moved into
glibc-doc-reference for licensing reasons.
Bugs: mailto:[e-mail]

11、glibc-doc-reference
理由同上，编程人员最喜欢的参考手册就是这个软件包了，可以称为Linux下C语言编程参考。此软件包信息如下：
Package: glibc-doc-reference
Priority: optional
Section: doc
Installed-Size: 7876
Maintainer: GNU Libc Maintainers <[e-mail]>

此参考手册有html和info两种格式，你可以用浏览器打开/usr/share/doc/glibc-doc-reference/html目录下的手册一页页看。把这里每个网页一点点看完了学会了基本上没有搞不定的问题了。

12、manpages-dev
在编程的过程中有时会记不得某个函数的用法，通常这时查man手册是比较快的，所以把这个manpages-dev软件包安装上。想要看某个函数的用法就man它。软件包信息如下：
Package: manpages-dev

这个软件包提供系统调用和库函数的在线手册。

13、make
在进行大项目时，通常我们的程序可能是由很多源文件组成的，各个源文件生成自己的目标文件，多个目标文件才链接形成一个新的目标文件或可执行程序。
在某个源文件发生变化时，我们只需要按照这种依赖关系运行各命令重新生成程序即可，而不需要对所有源文件重新编译。哪个该重新编译呢？可以让make程序帮忙 维护，该软件包信息如下：
Package: make

Description: The GNU version of the "make" utility.
GNU Make is a program that determines which pieces of a large
program need to be recompiled and issues the commands to recompile
them, when necessary. More information about GNU Make can be found in
the `make' Info page. The upstream sources for this package are
available at the location ftp://ftp.gnu.org/gnu/make/. The
documentation for this package does not meet the Debian Free Software
Guidelines, and has been removed from this package.

Description: Documentation for the GNU version of the "make" utility.
This package contains the documentation for GNU Make. The upstream
sources for this package are available at the location
ftp://ftp.gnu.org/gnu/make/. This package has been stripped down to
only contain the documentation; since the documentation is covered
under a non-free license and thus has been moved to
non-free/doc. Make itself remains in Debian.

Description: The GNU Debugger
GDB is a source-level debugger, capable of breaking programs at
any specific line, displaying variable values, and determining
where errors occurred. Currently, it works for C, C++, Fortran,
Modula 2 and Java programs. A must-have for any serious
programmer.

安装好软件后就可以通过电脑上的文档自学gdb的使用了。

17、编辑器
要编写C程序，总得有个编辑工具吧？Linux下这类工具相当多，关键在于熟练掌握一种。
比如文本界面的编辑器vi, vim, emacs等
比如图形界面的编辑器gedit, kate, kwrite等
又比如IDE环境的：anjuta, eclipse, kdevelop等

选择一个自己习惯的熟练使用起来就行了。

这些只是基本的Linux下C编程环境必须的软件包。如果这些熟练掌握了，可以试试下面这些软件包：
autoconf, automake1.9, libtool, flex, bison
当然还有对应的文档用于自学。
甚至可以试试IDE环境下其它语言编程，比如gtk, qt等
