Hi,

I'm having a problem getting my Xspec local models library to load in isis. I definitely had it working before on the same computer, with earlier versions of the software.

Recently, I lost my hard drive, and although I recovered all important data, I decided to update fink (including gcc), as well as xspec, slang, and isis. So it's possible that I'm either doing something stupid in my installation of any of these pieces of software; or that there's a bug introduced somewhere in recent updates of Xspec or isis. 

I'm currently using: 

OS X 10.5.8 on Intel Mac (same as before)
gcc 4.4.2 from fink
Xspec 12.5.1n, built as a part of heasoft 6.8
slang 2.2.2
isis 1.5.0-20

Xspec, slang, and isis were all built using gcc 4.4.2 from fink.

The actual bug is this: I start up isis, type

require ("xspec");

and I get an error message like:

loading /path/to/local/models/liblocalmodels.dylib
Link error: dlsym(0x1224d50, model_name): symbol not found
(last line repeats for all model_name in the library)

I know that liblocalmodels.dylib works, because I can use local models in xspec.

Any suggestions? Thanks,

Maurice
