IDL 7.1 crashes on MacOS X -- malloc error 1383 3
Started by Deleted User
I installed my IDL while being a guest at an institute, and it worked well using their license.&160; When I came back home, I tried to switch to the remote license of my home institute, and must have messed something up.&160; IDL won't start anymore.&160; It doesn't seem to be a problem of the license, since the crash happens before any message about licensing appears.
At first, the message was "segmentation fault" immediately after the > idl command.&160; After a while, it change...

Dear All,
I'm trying to run IDLDE 7.1.1 from a remote host (spectral), using an x-server, on my pc (rbantges). However, the x-server crashes each time before completing the IDLDE window (notably, no fonts are displayed). An image of how far the process gets before crashing is attached at the end of this message.
The remote&160;host computer reports the following error: "IDL Workbench: Fatal IO error 104 (Connection reset by peer) on X server rbantges:0.0".&160;

voxel_proj box thickness 1223 0
Started by Deleted User
Hello,
does anyone know how I can change the thickness of the box lines
automatically drawn when I use the voxel_proj method Depending on
the viewing angle, the lines disappear and change their thickness,
so I would like to make them stronger.
Cheers,

Hi.

WINDOWS file redirection and pipe operations 1184 1
Started by Deleted User
Hello everybody,
According to IDL online help "the normal UNIX file redirection and pipe operations work with IDL".
If idl & idl.out & causes IDL to execute in the background (reading its input from the file idl.inp and writing its output to the file idl.out), how can we translate that shell command working on windows OS
Thanks for your help,

input from external file 1239 0
Started by Deleted User
Hello everybody,
I should assign some input values (constants, file paths) to an IDL program from an external file, without modifying any part of the original code. In other words, I have&160;a .txt file&160;containing my input&160;and&160;a "black box" program, I just know what it needs to work. I think I could try with a script, a .pro batch file, but I can't figure it out. Does anybody has any good idea
Thanks for your help,

Hello everyone
I want to convert the EVF polygons with the holes&160;to ROIs in my pro file.here's the direction I would take:
(1)Open and read the EVF file(s) using the functions ENVI_EVF_OPEN,
ENVI_EVF_READ_RECORD, etc.
(2)Convert the geographical coordinates to image coordinates using
ENVI_CONVERT_FILE_COORDINATES.
(3)Convert the EVF polygons to ROIs using ENVI_CREATE_ROI and
ENVI_DEFINE_ROI.
But the result is not the same as ones in ENVI using 'enport layers to roi'.

I checked and found that this is a command in the "makefile" file in the callable&160; folder. Is this a version related problem

Change build order 1083 1

I am desesperately trying to change the build order for files in my IDL project with no result. I can open the window with the file list, but I can not move files up or down. Any way around it
Other than that, if IDL developpers are reading, I would like to state that I HATE the new environment that came with version 7.0. NONE of my old projects can be used. It is a disaster. I have lost years of work.

Making an array from a function 1073 2
Started by Deleted User
Greetings,
&160;
I am trying to write a function&160; which creates an array.&160; While I have determined that the function actually does create the array within the function itself, it does not create the array externally.&160; Thus, I only receive a value of '0' from running function.&160; What am I doing wrong
&160;
Sincerely,
