Perhaps I'm missing something obvious, but here goes...
I have an IDL HASP liscence on my Windows 2000 computer, and IDL runs
fine. However, when I try to call IDL from a C program, using
IDL_Win32Init, two interesting things happen.
First, when I run the program, it looks for the liscence file in the
parent of the directory the program is running from. Not the actual
liscence directory for IDL. Not just the directory from which the
program runs. Strange. Anyhow, this is easily solved by copying the
liscence file into the directory it looks in.
Second, after the liscence file is where the program looks, I run again
and get a message telling me that the liscence file is not formatted
correctly. It's the same liscence file that I use to run IDL
interactively, so I'm not sure what to do.
Are there specific liscencing issues for callable IDL?
Aside: This question was prompted by an attempt to get around an problem
I mentioned in another thread on memory leaks. I'm currently pursuing
two paths in parallel: (1) find the source of the leaks, and (2) avoid
the memory problem by using callable IDL to run pieces of the batch job
independently from separate processes (thus not allowing the leaks to
add up). Path 2 could be easily done in UNIX using non-interactive IDL
and SPAWN, but Windows does not support this. Thus, I'm going the
callable IDL route.
