Let's say that I am distributing a package with a DLM. Of course the
problem with DLMs is they can be both IDL version-dependent, and
architecture dependent. At least mine is. :-) Let's say for the
moment can make a big library of binary DLM files for all the
architectures and IDL versions I know about.
The question is, where should the DLMs? The nicest place would be the
IDL binary directory. Of course that assumes that users have
permission to put things there.
Another thought is to have a separate "site" DLM directory. That
requires the user to set their IDL_DLM_PATH environment variable
before running IDL. This works, unless users are in heterogeneous
environment (ie, like my lab's), in which case they won't know *which*
directory to set it to ahead of time. Sadly, the IDL system variable
!DLM_PATH cannot be set at runtime, so there is no way to discover it
on the fly.
Has anybody else run into this issue? Should I just assume that users
will be able to�write into their system $IDL_DIR/bin/bin.${arch}
directory?
Thanks,
Craig

I think RSI is responding. I understand that the next version of IDL
will have a feature to make this easier. Now all that is needed for
everybody to upgrade to IDL 5.5 immediately, right? :-)

In article <onitjc4h0k.fsf@cow.physics.wisc.edu>,

Ouch! For rmfit, we ended up distributing source code for the *nix users
and asked them to make the DLM themselves. The Mac binary is available at
special request; as for Windows...

For Macs, this is the only choice I can see. Unix is a lot harder, for
reasons you've mentioned below. In our distribution, the DLM goes in a
subdirectory of the source tree and users have to set up their
IDL_DLM_PATH. I put all this in the installation notes and hope they will
only have to do this once.

Too true, perhaps it's worth a note to RSI to put in a change request?
