Call_External and the C Math Library [message #6313]

Hey all,

Has anyone experienced problems getting IDL's call_external to behave
when called on C code that uses the standard C math library? I have
some C routines that use pow and sqrt, and when call_external was
dumping core, I tracked the problem down to the lines that contained C
math library calls. Math.h is included in the C code, and -lm is on
the link line. I tried using an explicit interface in the C code
(ie. double sqrt (double);), but that didn't help. Has anyone seen
this before and found a fix?

Thanks in advance,

Charles Cavanaugh
