[ncl-install] mac installation issue

[Mary Haley]

Hi,

In order to set an environment variable so that you don't have to do it every time you log in, you need to do it in one of your .xxxx files in your home directory.

If you type this:

cd
ls -a

You may see files like:

.profile
.bashrc

These type of files get "executed" every time you log in, so this is a good place to set environment variables.

I recommend putting the lines in your .profile file, if you have one. Use a UNIX editor to edit this file and add the needed NCARG_ROOT and PATH lines to the end of the file, the same way you typed them on the UNIX command line:


export NCARG_ROOT=/Users/Crystal/usr/local/ncl-6.2.0
export PATH=$NCARG_ROOT/bin:$PATH

--Mary
