The build looks o.k., and the error you are getting is more of a
DLM_PATH problem so I would start there.
Since you aren't seeing "% Loaded DLM: RHTGRCAMERA." when the
application compiles and you aren't seeing any "Unable to load DLM" type
errors I would guess IDL just can't find the .so/.dlm. What happens if
you simply try to compile the IDL code? If IDL didn't find the .dlm you
should get a syntax error on every line where a dlm function is referenced.
FWIW, I always install DLMs in one of two ways: I usually put them in
$IDL_DIR/bin/bin.x86 (would that be bin.darwin for you?) The lazy man's
approach which sidesteps the whole path issue. When I distribute .sav
files for the VM, I put the DLMs in the same directory as the .sav file.
If you move .dlm/.so files you either have to restart IDL or use the
DLM_REGISTER function to force IDL to update it's lookup tables. You
can also use the DLM_LOAD function to determine if IDL can find the dlm:
IDL> dlm_load,'rhtgrcamera'
% Loaded DLM: RHTGRCAMERA.
On subsequent calls in the current session, or when a DLM is already
loaded, you won't see the "% Loaded DLM:" output.
I don't know why your IDL_DLM_PATH doesn't seem to be working... Are
the .dlm and .so files both in that directory?
