Thanks, Jennifer!   My student has successfully installed grads on his new Mac.

The de-support of X11 by Apple is unfortunate, and that is my best polite happy face way of saying it in a public forum.

1. If X11 does not appear under the Applications->Utilities Menu, then you will definitely need to install XQuartz.
2. If you do have libX11.6.dlylib under /usr/X11/lib/, then you should try setting the environment variable  LD_LIBRARY_PATH to /usr/X11/lib and see if that fixes things.
3. If setting the LD_LIBRARY_PATH environment variable doesn't solve your problem, then you will need to get to know the MacPorts Project (http://www.mactports.org<https://urldefense.proofpoint.com/v1/url?u=http://www.mactports.org&k=wf2FkHoZDP5jrUw2KePZ5g%3D%3D%0A&r=qsUUC4acs8C2w63cTW9n1GgnhTSdfk%2BxSgP6NoKUDus%3D%0A&m=llONxhTzX2HeH%2Bthweymxz3sYtdRZB%2B8jIevaDUN8BI%3D%0A&s=bbaefe2129bf79b8248977011f109b4d14a625bc6063514d3dadb8d91f9abf93>).  MacPorts will effortlessly install all kinds of utilities, programs, and software libraries on your system. MacPorts puts everything under /opt/local/.

Great news -- I have just discovered that MacPorts has a port for GrADS! A special shout-out of thanks to 'takeshi' and 'ryandesign' -- they are the ones who have set it up. As I am writing, it is installing the supplibs...

Anyway, when I built the GrADS executables for distribution, I linked dynamically with the X11 library installed by MacPorts under /opt/local/lib/, not the native X11 under /usr/X11/lib/. I really can't say whether I did that on purpose or not. I often switch back and forth between the two during testing to make sure that both are working properly. And since X11 support will not be a part of native OSX in the future, it's just as well to get started using MacPorts because that will probably be the way many third-party tools will be supported in the future.

Hi,

My student got a brand new Mac OS X 10.8.4.   We cannot install grads on the Mac.
We put all the file in /usr/local/bin and /usr/local/lib as instructed in the INSTALL.
Following is the error message when we do grads:

dyld: Library not loaded: /opt/local/lib/libX11.6.dylib
 Referenced from: /usr/local/bin/grads
 Reason: image not found
Trace/BPT trap: 5


Type "locate libX11.6.dylib" to see if you have the X11 libraries on your disk.  If so, you need to add the directory where they are to your LD_LIBRARY_PATH.

However, it is more likely that you have run into the de-support of X11, which used to come standard with Mac OS.  Now, however, it does not, so you need a third party package for X11.  One package for this is XQuartz:

Thanks!
