Linux operating system C language programming considerations what, I believe that many inexperienced people are helpless, for this reason this article summarizes the causes and solutions of the problem, through this article I hope you can solve this problem.

I. Use of tools This article refers to www.eepw.com.cn/article/249694.htm

1, learn to use vim/emacs, vim/emacs is the most commonly used source code editor under linux, not only to learn to use them to edit source code, but also to learn to use them to find, locate, replace, etc. For beginners, vim is recommended, which is also the text editor I currently use.

2. Learn the rules for writing makefiles, and use the tools aclocal, autoconf and automake to generate makefiles.

3. Master the basic usage of gcc and gdb. Knowing how to use gcc is useful for building a package. When a package contains a large number of files, you can also manually compile it with gcc, and you will have a clear understanding of the dependencies among the files in the package.

Master the basic usage of svn/cvs. This is linux and the most commonly used version management system in the open source community. Try participating in some of the open source projects on sourceforge.

Linux/Unix system calls and standard C libraries

System call application software and operating system interface, its importance naturally needless to say, must master. Recommended learning materials for Mr. Steven UNIX environment advanced programming (APUE).

III. Library learning

No matter which platform to do software development, it is very important for library learning. There are many development libraries under linux. I mainly introduce some libraries that I often use.

1. Glib library

Glib library is the base library for gtk+ and gnome, and is cross-platform, available under linux, unix and windows. Glib library for Linux platform development as MFC for Windows platform development, many open source projects are heavily used glib library, including gimp, gnome, gaim, evolution and Linux cluster software heartbeat. Because the glib library comes with basic data structure implementations, you can learn basic data structures (including linked lists, trees, queues, and hash tables) while learning the glib library.

2. libxml library

libxml is a basic library for parsing XML files on Linux platform. Now many utility software use XML format configuration files, so it is necessary to learn about it.

3, readline library

Readline library is bash shell library, if you want to develop command line programs, then use readline library can reduce a lot of workload, such as bash in the command line auto-completion, in readline has been implemented, of course, you can also use your own implementation instead of library behavior. Readline library has a lot of website introduction, as long as Google Readline can find a bunch of it.

4. Curses library

The curses library used to be part of vi, but was later pulled out of vi as a separate library. The curses library is especially useful for writing terminal-related programs, such as locating output in a row or column of a terminal, changing terminal font colors, and terminal modes. The curses library for Linux uses the GNU implementation of ncurses(meaning new curses).

5. gtk+ and KDE libraries

These two libraries are the basic libraries for developing GUI applications. Most GUI programs under Linux are developed based on these two libraries, so it is necessary for them to learn.

IV. Network learning

Network this thing is too wide, recommended learning information Mr. Steven UNIX network programming (referred to as UNP) and TCP/IP protocol detailed explanation, further words can learn to use libnet to write network procedures.
