最近在学习Linux，我采用的版本是CentOS 5.6 因为原来学习时使用的这个发行版，手中的书全部是鸟哥的（不是做广告） 所以最近下载了最新版本的5.6安装并学习
在Windows系统里经常用录屏软件录制一些操作，方便自己也方便同事。换了Linux后也想用Gnome界面录屏，在网餐搜索了一下，介绍的是五种，我采用了recordMyDesktop做为自己使用的软件。
下载软件：
wget
wget
我采用的是源代码编译安装，先介绍一下上面的两个软件包，
第一个是主程序
第二个是界面配置工具，我采用的是Gnome界面所以下载了gtk
安装，在Centos上用源代码安装软件最麻烦，因为没有找到RPM包 硬着头皮用源代码安装。
先安装第一个主程序（下面是官方发布的安装说明）：
You will need the development headers(i.e. packages ending with -dev or -devel（在安装软件时先查看下面的包是否正确安装，这是包依赖包）
depending on the distribution you use) for the following:
X
libICE-dev
libSM-dev
libXext
libXdamage
libXfixes
libogg
libvorbis
libtheora
If you got a release tarball, to compile the program you have to go through the regular drill:（这个是安装过程利用这个 就可以）
~$ gzip -d recordmydesktop-x.y.z.tar.gz
~$ tar -xvf recordmydesktop-x.y.z.tar
~$ cd recordmydesktop-x.y.z
~$ ./configure
~$ make
~$ sudo make install
另外 语音的支持：
If you want to compile with ALSA support, you will also
need the libasound headers.If they are not found, OSS
will be used and you must have the sys/soundcard.h header.
To use OSS regardless of whether or not you have the ALSA
headers, you can use the --enable-oss switch during
configuration.
Last, you need the regular headers, plus the ones for pthreads
(both of which you should have if you have compiled anything else before).
Of the above, the most likely to be missing are probably those of libXdamage and libtheora
but any recent linux distribution should offer an easy way to get them.
安装完成，采用recordmydesktop 来测试一下
安装第二个界面配置软件（复制官方安装说明）；
DEPENDENCIES:
（利用yum检查依赖包）
GNU automake >=1.5
Python >= 2.4
PyGTK>=2.10 or PyGTK>=2.8 with gnome-python-extras >= 2.11.3 (Be carefull since this is checked on runtime. )
recordMyDesktop 0.3.5
To compile the program you have to go through the regular drill:
（安装步骤）
~$ gzip -d gtk-recordmydesktop-x.y.z.tar.gz
~$ tar -xvf gtk-recordmydesktop-x.y.z.tar
~$ cd gtk-recordmydesktop-x.y.z
~$ ./configure --prefix=/usr/
~$ make
~$ sudo make install
The --prefix=/usr/ option might not be necessary, but it
will prevent some problems when running the program
(if you get messages about module recordMyDesktop not found,
you have to use it).
After this you should get a menu entry under multimedia.
If you don't get one even after a logout/login from your WM
you can launch the program from a terminal like this:
~$ gtk-recordMyDesktop （命令运行）
在应该程序-影音里出现现gtk-recordMyDesktop菜单，安装成功
到此安装成功了，
感谢软件作者们，提供了这么好的软件和安装说明，
