) Build a C/C ++ environment in Ubuntu

I use the Ubuntu server version, which is easy to install and very simple. However, after installation, the operating system is almost a blank operating system with almost no content, so you have to install it. Because it is dapper (6.06), I use the following method to replace the software source: Vim/etc/APT/sources.

I prefer vim and installed it. Apt-Get install Vim By default, VIM has no syntax coloring, Modify/etc/Vim/vimrc You just need to remove the comments of syntax on. To make Vim easy to use, you also need to install some necessary plug-ins. Here I reference twoArticle: The first section describes some basic Vim skills. Mastering these skills can greatly improve the editing efficiency, but the powerful functions of Vim are not limited to this. Vim can also use plug-ins to Expand functions. Specifically, scripts are extended through scripts, including plug-ins, syntax highlighting, color schemes, and file type detection. Most of the scripts are written by VIM users, which solves user problems and makes Vim more useful. This chapter describes some of the most commonly used scripts, except for a "highlighted Syntax" script, which belongs to the "plug-in" type. Some basic knowledge about how to write scripts will be introduced in the next section. I use the Ubuntu server version, which is easy to install and very simple.
