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。

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。

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:

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)

#set path = (. /usr/local/gmt/bin /usr/local/bin /usr/local/lib /usr/ucb/ nfs r0 soft0 0 $path)

set path = (. gamitpath/gamit/bingamitpath/kf/bin gamitpath/compath)

setenv HELP_DIR $gamitpath/help/

setenv PATH "/usr/sbin:/sbin:${PATH}"

setenv MANPATH /usr/local/gmt/man:/usr/local/man:/usr/X11R6/man

setenv LIBPATH /usr/local/gmt/lib:/usr/lib:/usr/local/lib:/usr/i386-glibc21-linux/lib

#set gcclib direction

setenv LD_LIBRARY_PATH /usr/local/gcc-3.4.1/lib/

# set alias

alias cd 'cd \!*; set prompt = "[`echo $cwd`]% "'

alias pwd 'echo $cwd'

alias ls 'ls --classify'

alias ll 'ls -l'

alias la 'ls -a'

alias rm 'rm -i'

alias mv 'mv -i'

保存，OK，全部安装完成。在终端输入

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
