Ubuntu 7.10下安装NS2的曲折经历

Ubuntu 7.10下安装NS2的曲折经历

NS2是一个功能强大的网络模拟工具，下面介绍一下我在Ubuntu 7.10系统下安装NS2所遇到的艰难险阻，给后来者以借鉴。

问题一：刚开始安装时显示gcc can't create executables之类的提示

解决方案：
这是由于我用的是ubuntu免费邮寄的安装盘，安装后的系统中gcc是不能用来的开发的，只有一个空壳，所以需要重新安装gcc。先用命令： sudo apt-get remove gcc
然后sudo apt -get install build－essential 便成功解决问题。

问题二：再次安装NS2时发现安装至tk8.4.13时出现错误，安装中断退出。在安装日志上发现一句：x11/xlib.h nosuch file or directory 在网上查阅了资料，原来是x11M没有装。

解决方案：
先安装X11，命令为 sudo apt -get install libx11-dev
结果仍然出错如下：
checking for main in -lXbsd... no
checking for socket in -lsocket... no
checking for gethostbyname in -lnsl... yes

还是没有得到解决.分析了一下可能是x11没有安装完整，于是先输入:sudo apt-cache search x11-dev
得到以下信息:
libx11-dev - X11 client-side library (development headers)
xlibs-dev - X Window System client library development files transitional package
libghc6-x11-dev - Haskell X11 binding for GHC
libooc-x11-dev - X11 specific modules for the oo2c compiler (devel)
libgl1-mesa-swx11-dev - A free implementation of the OpenGL API -- development support files
分别安装上面的组件，命令如下：
sudo apt-get install libx11-dev
sudo apt-get install xlibs-dev
sudo apt-get install libghc6-x11-dev
sudo apt-get install libooc-x11-dev

然后继续安装，等了半天，安装完成！
