[ncl-install] Question in regards to NCL installation -Derek Mallia

[David Brown]

Hi Derek,
If you are using the default shell (bash) on your Mac, you should edit the initialization file .bashrc or .bash_profile file that should be in your home directory. Note that since the file name begins with a '.' it will not be visible if you just do an 'ls'. You will see it if you do 'ls -a'. Anyway you should edit the file and add lines like the following depending on where you installed NCL:

export NCARG_ROOT=/usr/local/ncarg/
export PATH=$NCARG_ROOT/bin:$PATH

If you are starting up with a csh derivative the file name might be .cshrc and the syntax will be a little different.  The http://www.ncl.ucar.edu/get_started.shtml#SetUpEnvironment page gives the csh commands. You can control the shell and init script used by opening the preferences for the Terminal program and looking at the 'Shell' tab. Hope this helps.

Last night i tried installing NCL to my 2010 macbook pro with some success, however there was a minor problem after the installation. When I did the initial test after the installation was completed, the graph example worked perfectly fine, and whenever I typed ncl into the command line the ncl program would open up in my working directory. However a issue occurred when I exited and reopened the terminal as I had to re type the NCARG root and the path where my ncl path resides to get NCL to run again. Granted ncl does seem to run fine when I do this, however its abit of a pain to have to retype everything all over again.

Also I'm not exactly totally proficient with unix commands and whatnot, so I may be a bit slow with the terminology!
