[ncl-install] NCAR Graphics test doesn't work

Tue Jun 16 09:44:24 MDT 2015

Mary,

Well that clears up the relationship between ncl and NCAR Graphics to me a little bit.  So thanks for that.  My actual need for ncarg is small to nonexistent, but I thought since I was playing around with it, I thought I'd try to see why it didn't work.  I guess that also explains a lot about the Fedora ncl package as well--doesn't work there, either ;-).

Hi Kevin,

To answer your first question, the binary is relocatable. You can put it wherever you want. You just need to be sure to setenv NCARG_ROOT to point to the parent location, and add $NCARG_ROOT/bin to your search path, which it sounds like you did.

For the "ncargex cpex08" issue: If you only plan to use NCL, then it's not important that this test work. The "ncargex" command tests the C and Fortran libraries for people that are using C and/or Fortran to generate their graphics, rather than NCL.

If you still want to get this test to work, then I think the issue is that you have a libXext.so.x.y file, but not a libXext.so file.  Usually libXext.so is a symbolic link to libXext.so.x.y. You might want to look into how this software was installed, and make sure it was installed correctly.

	But when I do 'locate Xext':

	<<havenerk at metappdev:~>>$ locate Xext
	>/usr/lib64/libXext.so.6
	>/usr/lib64/libXext.so.6.4.0

	System is: Linux 2.6.32-504.16.2.el6.x86_64 #1 SMP Tue Mar 10 x86_64 x86_64 x86_64 GNU/Linux

	What do I have to do to get NCAR Graphics working?  Is there a resource on the website that I'm missing?
