Hello,
Several times I called a fortran routine from a c program, it was OK.
I am trying to do the same with complex numbers in the call.
Is it a problem ?
in c, I use double complex
in f95, I use COMPLEX*16
Typo? From f2c.h:
typedef struct { doublereal r, i; } doublecomplex;
This is f2c, I tried to avoid to use this old package
now there is is a complex librairy in gcc
which has all the functions for the complex,
In my opinion, f2c is only recommanded when you use the converter f2c
Actually, f2c, is not capable to convert all the Frotran progams, and it does
not make a great job as soon as the code is a bit complex
my fortran cade translated to c by f2c does not work
I get a segmentation fault:
are the formats of the complex incompatible different?
Do I need to add a compilation option?
Thank.
