Console does not print under Mac Lion and IDL 8.1 1385 4
Started by Deleted User
Using IDL 8.1 (Workspace) under Mac Lion 10.7.2, its command line console stop printing at any moment. Sometimes I recover printing capability by asking to print something as numbers or numerical array, but generally it keeps without printing/reporting until next IDL restart. Please, somebody has a solution for this

Upgraded to Mac OSX 10.7.3, and now IDL 8.0 crashes on opening 1045 4
Started by Deleted User
IDL 8.0 was working fine before I updated my machine to Mac OSX 10.7.3 from 10.7.2. Now, when I try to open IDL, I get a full crash report. I can open ENVIIDL, but IDL is open only in an X11 pane. My guess is there is a problem with the Workbench. Has anyone seen this problem before

IDL Java Bridge 1357 3
Started by Deleted User
Hello All,
I've been using Sergey Koposov's, IDL_SQL Java library, to connect IDL 7.1 to a MySQL database and when I tried setting it up on another Windows machine with IDL 8.0 we could not get it to work for a few days. We finally figured out what the problem was and I thought I would throw this out for your information. IDL_SQL uses the IDL Java Bridge and that can be configured with the idljavabrc file in the users home directory. We have Java 7 installed on the machine and we pointed...

Mesa DLLs Compliant with Applications Built Using Visual Studio 2010 1419 1
Started by Deleted User
It appears the Mesa DLLs were built using Visual Studio 2005 and contain no embedded manifest information for specifying the C runtime associated with Visual Studio 2005.
Regretfully, C applications built using Visual Studio 2010 which want to use IDL, require that the MESA DLLs either 1) have embedded manifest information, or 2) be built using Visual Studio 2010.
1) Are there any plans to provide the Mesa DLLs with embedded manifest information, such that the Mesa DLLs can locate th...

Errorplot on grouped barplot 1248 3
Started by Deleted User
Hi All,
I'm trying to get the errorplot function to work on a grouped barplot.
So I made a grouped barplot with the barplot function and the keywords 'nbars' and 'index'. Now I want every bar to have an error bar. The problem is that the barplot function uses 'index' to separate the bars, but i can't refer to this 'index' in the errorplot function.
How to do this
Thanks in advance!
Cheers,
Wouter

porting an IDL/ENVI license to another OS? 1024 1
Started by Deleted User
My company, a small consulting firm, has several IDL/ENVI licenses, that all use a USB 'donegal' (sp) as a license manager/server. At the present, we cannot readily afford to upgrade or purchase a new license. I wanted to know, is it possible to install our current version of IDL and ENVI (7.0 and 4.5, respectively) on a Linux machine, and use the same license handling I'd be most helpful to know if this is possible.
