Calling f90 subroutine from IDL [message #56829] Wed, 14 November 2007 07:41

I have been trying to use Fortran do-loop instead of
IDL FOR... ENDFOR for the loop of big arrays.
I'm running IDL 6.1 on IRIX64.

After I searched for how-to in this group, I think inserting
Fortran subroutine in IDL seems successful. But when I use
f90 compiler, it didn't work. Only when f77 compiler
is used, it worked.
Are there some reasons for that?

FYI, I compiled Fortran routine like this:
f77 -64 -c aaa.f
ld -64 -shared -o aaa.so aaa.o

Thanks,
