服务器评测
从安装的过程来看，Ubuntu Linux在台式机上会安装gcc，但是笔记本上则不会，所以在第一次装的时候并没有成功，虽然从头到尾都安装了，没有中断，但最后采用doy验证的时候没有通过。

下文是根据原文加自己的安装过程，总结出的内容，蓝色为原文，内容可能上下有出入，但不影响安装。
出入的部分主要是软件的版本显示问题（原文是10.34，我安装的是10.35）和安装路径。
首先，安装GCC,因为在root模式下，命令行没有sudo
apt-get build-dep gcc
链接1采用两种方法，比较了大小后决定采用第一条，就是上面的命令。
通过gcc –version确认版本为 GCC 4.3.3
Gamit安装需要csh（tcsh）环境、GNU gfortran 4.2编译器和libx11－dev库支持。gfortran是软件推荐使用的编译器。libx11-dev是X11的程序开发库，它提供的lib.h和 libx11.a（libx11.so）是Gamit安装必须用到的两个库文件，主要是为Globk的提供图形库支持。以上三个条件却一不可。
Ubuntu系统没有csh，默认为bash。因此要先安装csh。
Ubuntu系统自带了gcc4.2，但是却没有安装gfortran编译器。而你安装时安装程序会调用默认的gfortran编译器，除非你指定gcc为你的编译器。
首先，以root身份登录，打开终端，输入
apt-get install csh
系统自动下载并安装csh，安装完成后在终端输入
chsh
提示
正在更改 root 的 SHELL
请输入新值，或直接敲回车键以使用默认值
登录 Shell [/bin/bash]:
输入
/bin/csh
修改bash为csh。重新起动Ubuntu，并以root身份登录，打开终端，输入
# echo $SHELL
返回s“/bin/csh”,说明SHELL修改成功。
接着输入
apt-get install gfortran
系统自动下载并安装gfortran。
在输入
apt-get install libx11-dev
系统自动下载并安装libx11-dev库支持。
安装gamit 10.35
定位到gamit的下载路径（即安装路径）
准备工作：
chmod +x install_software
修改install_software文件内容
“usr -name libX11.a”为”usr -name libX11.so”，一个是静态共享库，一个是动态共享库。
makefile.config，修改：
# X11 library location – uncomment the appropriate one for your system
# Generic (will work on any system if links in place)
X11LIBPATH /usr/lib/X11
X11INCPATH /usr/include/X11

gamit<路径>/libraries压缩包里，修改Makefile.config/Makefile.config.bak中的一组参数
MAXSIT 55
MAXSAT 32
MAXATM 13
MAXEPC 2880
将MAXATM改为25。
执行 ./install_software
安装程序install_software启动，搜索安装目录/opt/gamit10.34下的全部压缩文件，提示

If you need help with command line options type CTL_C now and type
install_software -help on the command line
The compressed tarfiles will be removed after extraction of the
directories, but except for that, the script may be stopped and
rerun safely from any point. Tarfiles to be uncompressed:

where_i_work is a 3 character identifier for your solutions
至此，软件已经安装成功。但要始软件能够正常使用，还要修改“主文件夹”下的“.cshrc”文件.该文件是用户的C SHELL配置文件，默认为隐藏文件。必须将Gamit的安装目录添加在里面，否则将无法在终端使用Gamit命令进行数据解算。
由于Ubuntu默认使用bash，所以，用户主目录下并没有csh的配置文件，你需要在自己的主文件夹下建立一个“.cshrc”文件，并输入内容如下
#
# This file is applicable to all C-shell users.
# set prompt
set prompt = “[`echo $cwd`]% “
set history = 50
set gamitpath = /opt/gamit10.34
set path = (. /bin /sbin /ect /usr/bin /usr/sbin /usr/ucb /usr/bin/X11 /usr/X11R6/bin $path)
set path = (. /usr/local/gmt/bin /usr/local/bin /usr/local/sbin /usr/local/lib /usr/lib $path)

alias pwd ‘echo $cwd’
alias ls ‘ls –classify’
alias ll ‘ls -l’
alias la ‘ls -a’

alias mv ‘mv -i’
保存，OK，全部安装完成。在终端输入
doy
返回
DOY: Converts various date formats
DOY: Converts various date formats.
Runstring:
% doy <jd/year> <doy/month> <day> <hr> <min>
or
% doy <gps_week>W <gps_sow/gps_dow>
or
% doy <DecYear>Y
where jd is Julian date (assumed if only one argument)
year is calender year
doy is day of year (assumed if two arguments)
month is month
day is day of month.
hr min is hrs and minutes of day (Only if ymd form used).
In the second form (i.e. W appended to the first value),
the entries are assumed to gps week no and the second entry
(optional) is either gps day of week (0-6) or seconds of
gps week.
NOTE: GPS Day of Week runs from 0-6 (Changed May 20, 1997).
In the third form with Y appended, the argument is taken as
deciminal year. (Versions after 2004/12/21 correctly account
for leap years in converting deciminal years back to Julian dates)
The conversions made are based on the number of arguments
passed.
NDOY: Version of doy of year which takes keyboard input in the
forms above. (^D ends program input).
Example: doy 92 200
Date 1992/07/18 0:00 hrs, DOY 200 JD 2448821.5000 MJD 48821.0000
GPS Week 653 Day of week 6, GPS Seconds 518400 Day of Week Sat
