Just a guess, but it still doesn't seem like you are linking correctly. I
get the same error (except the 32/64 are swapped) when I try to load a 64bit
dlm in the 32bit version of IDL which is what I would expect. So it seems
that your DLM is still 32-bit?
I don't know, and unfortunately I can't point you to a tool that could tell
you more, but I can suggest using gcc to link instead of ld. I'm compiling
64bit DLMs and I *think* they would work in the 64bit version of IDL and
that is the only real difference that I can see between your makefile and
mine.
CC=gcc
X_CFLAGS=-fPIC -m64 -mcpu=v9
X_LD_FLAGS=-shared -m64
LD=gcc

Rick,
I modified my Makefile, using gcc with your flags instead of ld, and
it works! Thanks for the help.
