Re: [Condor-users] Problem with DLLs

["Dr Ian C. Smith" <i.c.smith@xxxxxxxxxxxxxxx>]

I've been experimenting with this and I have got my application working at 
least
by setting the USERPROFILE env var (can be a junk value it doesn't matter).
Whether this is a panacea for other win xp apps I doubt it. Although
it does fit in with the other postings regarding apps accessing the
user's profile. This is the reasoning I followed:

1. Got Condor to run jobs under my username, accessing the same file
  files as I use interactively, on my PC. Doesn't work.

2. Captured all of my env vars and put them in .bat file so that they
  are all set before the app runs under condor. Works fine.

3. Deleted env vars one by one until job no longer runs. Found that
  only USERPROFILE needs to be set.

4. Run Condor job under its default username (condor-reuse-vm1). Still
  works OK - so is there anything special about the profile ?

5. Set USERPROFILE to junk value. Job still runs OK.

6. Put in all of the file staging so application files are now copied to the
  condor execute dir. Everything fine.

7. Run job on the "real" production pool rather than own PC. Things still
  work - time to go for a beer :->

I was interested in the comments regarding Matlab and Cygwin. I tried
to get Matlab compiled standalone apps to work for ages without much
success. Accessing the run time libs (the MCR as Matlab call it) from
a Novell server worked fine but I had problems accessing the actual
standalone app. As you are no doubt aware this isn't a monolithic
.exe but whole bundle of files stored hierarchically in directories.

I zipped these up and initially unzipped them using the Cygwin uzip
(needed to stage the Cygwin DLL as well) but kept getting the
"Access Denied" error. The files where unzipped OK but there was
just something that windoze didn't like about them. When I unzipped
them using a standard zip .exe program everything worked fine.
Very, very strange !

regards,

-ian.
