Hi Joe, At the time of release for IDL 7.1, the supported version of Mac OSX was 10.5.1. Currently, IDL 8.4.1 is not even officially supported for Mac OSX 10.10 because it was not available at the time of development. However, your best bet for getting IDL to run on Mac 10.10 is to upgrade to IDL 8.4.1 which many users have successfully installed and have not needed to make many changes to get it to work properly. Unfotunately, I have not heard of somebody getting IDL 7.1 to work on Mac 10.10 so I would recommend upgrading your version of IDL if you can.

I've managed to get a bit further with this by using the UNIX-style installer 'idl711darwin.i386_pcc.tar.gz' provided by Exelis tech support. After installing via command line I had to do the following: 1) Backup and remove: /idl71/bin/bin.darwin.x86_64/libz.1.dylib /idl71/bin/bin.darwin.i386/libz.1.dylib and replace with copies of: /usr/lib/libz.1.dylib 2) Add the following line to .bash_profile: . /.../idl71/bin/idl_setup.bash 3) Start a new terminal session in the install directory and run 'idl'. This seems to work pending licence file path setup. The 'idlde' command appears to work, but then interaction with the GUI throws up the following error in the terminal: idlde[22817:504508] Exception raised!: Error loadingFinderKit : dlopen(/System/Library/PrivateFrameworks/FinderKit.framework/FinderKit, 1): Library not loaded: /usr/lib/libcurl.4.dylib Referenced from: /System/Library/PrivateFrameworks/DiskImages.framework/Versions/A/DiskImages Reason: Incompatible library version: DiskImages requires version 7.0.0 or later, but libcurl.4.dylib provides version 5.0.0 I've seen this libcurl.4.dylib problem with Yosemite in a few forums, but I'm unsure if I need to update a curl package, or if this is an incorrect path problem, or there are two competing libraries or something. Yosemite installs don't have a usr/local/bin path for curl or curl-config. Any help would be great! Joe

Can confirm that, once licensing is set up, IDL7.1 does run ok in OS X 10.10.3 after the above changes, from both command line and DE. The above library error does get printed in the terminal when clicking prompts in new windows (e.g. to set working directory after initial install) but doesn't seem to affect things in the environment.

After the above changes, I find that everything works from the command line but the DE doesn't seem to work properly. The DE opens with no errors in the console but the command line doesn't seem to work -- nothing happens when I enter anything. Also there's nothing listed in the debug or variables views which normally have some things listed at startup. Any idea what might be going on? I'm having trouble googling it because it's hard to describe. Thanks!

I also migrate my idl 7.1 to Yosemite, it can run in the terminal but with some error for xprinter: $ idl IDL Version 7.1.1, Mac OS X (darwin x86_64 m64). (c) 2009, ITT Visual Information Solutions Error: eBadXPPATH: Bad value for XPPATH (~/resource/xprinter) % Error opening printer. And it caused a problem for plotting: IDL> a = findgen(100)/!pi IDL> plot, a % PLOT: Error opening file. File: ~/resource/fonts/hersh1.chr No such file or directory % Execution halted at: $MAIN$ How to fix it? Thanks!

I set the XPPATH to /Application/itt/idl/resource/xprinter in my .profile file, and the error for XPPATH is gone. But the problem for plotting is still the same, I guess it is due to the environment variable setting problem, but I have not solved it yet.

One thing you may try is to source the IDL setup file for the shell script that you are using (idl_setup.bash or idl_setup.ksh) which lives under /Applications/itt/idl71. This would be to set the IDL_DIR and other environment variables which may not be set. Apart from that I'm not sure what the problem is. The supported OS version for IDL 7.1 on Mac was 10.5 when it was first released and here is a link to that information: http://www.exelisvis.com/Support/Help... There have been quite a few changes to Mac OSX since 10.5 which will likely keep IDL 7.1 from running as expected. There are also many bugs that will be present in the older version of IDL that are not there in IDL 8.4. Like I mentioned before, the next version of IDL (IDL 8.5) will support Mac 10.10 and should be coming out in a few months.
