Because GMT works best in conjugation with UNIX tools we
suggest you install GMT using the Cygwin product from
Cygnus (www.cygnus.com/cygwin). In short, Cygwin
provides the bash shell (Bourne Again shell); in this shell
you have access to most standard GNU development tools such
as compilers and text processing tools (awk ,
grep , sed , etc.).
If you don’t mind learning bash scripting19.3 you can write any
type of GMT scripts (The GMT examples also come in
bash form).
Follow the instructions on the Cygwin home page on how
to install the executables; they are in ZIP format and the
whole package comes with an installer. It is difficult not
to do this correctly. Follow their advice on setting a
larger environmental space, and
copying sh.exe to /bin.
You need as always to install netCDF. Look at the netCDF
home page19.4 and locate the
discussion of a WIN32 port. Following the links gives you
either the option to ftp a ready-made libnetcdf.a
library or to learn how to make your own in Cygwin.
GMT 3.3.1 installs without a hitch provided you make a few
changes to the makegmt.macros file:
- 1.
- In Windows/DOS, set the two environmental variables
HOME and GMTHOME to point to your ``home'' directory while
running Cygwin and the GMT install directory. These two
parameters should be defined
in the autoexec.bat file and could be something
like19.5
- SET HOME=C:
USER
- SET GMTHOME=C:
GMT3.3.1
- 2.
- In this home directory, make the file .bashrc where
you place a few definitions:
- set HOME=//C/USER
- set GMTHOME=//C/GMT3.3.1
- 3.
- Then, copy makegmt.macros.orig to makegmt.macros,
and edit the latter in the following way:
- Change CSH = csh to bash
since you will need to use the bash version of the initialization
utility gmt_math_init .
- Set CC to gcc .
- Uncomment the DOS macro since the executables under
Cygwin has the extension .EXE.
- Select the preset CC_OPT flag for Cygwin.
- 4.
- In the GMT src directory, edit the bash script cygwin_prep_gmt.bash and modify the two
directory variables as indicated. Then, make various
directories and set required links with the command
``bash cygwin_prep_gmt.bash''.
- 5.
- You may now do ``make all'', ``make install'',
and ``make clean''.
- 6.
- If you also installed the example scripts you can test
GMT by running ``make examples''.
