I have been trying to call some Fortran routines from within IDL via the
CALL_EXTERNAL routine and use c code wrappers. I have the snall info file
produced by Jeff Valenti (from Mar 26, 1992) and can make his example
work. Unfortunately, when I try to get my own code to work, I am rfinding
that IDL is crashing with the following types of error message:
ld.so: call to undefined procedure _return_ from 0xf73d20f4
which seems to imply that my fortran routine is not being linked
witha library containing the RETURN routine. I am compiling using the
-c -pic options and linking with libF77.a and libm.a. Anybody have any
ideas where I'm going wrong? Unfortuately the FORTRAN code is a bit
too large to re-write it in IDL and doesn't easily lend itself to
piping.
Thanks

Sounds like you don't have the (right version) export.h include file being
included - usually found in the $IDL_DIR/external/ directory. If you have an
old version of this, it may not have the IDL_MEMINT definition - it was added
with some (5.0????) version.
If this doesn't work, could you send me (by email) the whole "session" output
(from beginning to end), with all error messages?
