Linux 开发工具

一：除了vim, 还有哪些编辑器, 对比编辑器之间的区别和优缺点. 

二： 除了gcc, 常用的编译器(不限制编程语言, 不限制平台).

三：为什么调试的时候需要编译选项中添加 -g. readelf命令. 

-g 
Produce debugging information in the operating system’s native format (stabs, COFF, XCOFF, or DWARF 2). GDB can work with this debugging information. 
On most systems that use stabs format, -g enables use of extra debugging information that only GDB can use; this extra information makes debugging work better in GDB but probably makes other debuggers crash or refuse to read the program. If you want to control for certain whether to generate the extra information, use -gstabs+, -gstabs, -gxcoff+, -gxcoff, or -gvms (see below). 
GCC allows you to use -g with -O. The shortcuts taken by optimized code may occasionally produce surprising results: some variables you declared may not exist at all; flow of control may briefly move where you did not expect it; some statements may not be executed because they compute constant results or their values are already at hand; some statements may execute in different places because they have been moved out of loops.

这样就便于调试

四：. 在Linux下实现进度条程序. 通过makefile进行编译. 建议自主完成一个彩色的进度条. 

五. Linux下软件安装的几种方式(源码安装, rpm安装, yum安装). 理解rpm安装和yum安装的区别.
