Hello,
I am tring to compile a program composed by .f and .c files.
I am using gcc :

gcc version 3.2 20020903 (Red Hat Linux 8.0 3.2-7)

and intel fortran compiler 7.0:

Intel Fortran Compiler for 32-bit applications, Version 7.0 Build 20021028Z
Copyright (C) 1985-2002 Intel Corporation. All rights reserved.
FOR NON-COMMERCIAL USE ONLY

GNU ld version 2.13.90.0.2 20020802
Supported emulations:
elf_i386
i386linux
elf_i386_glibc21

The problem come when the program link and it does't reconise the c subroutine because it looks for somethinds like namesubroutine_

In the makefile I use the option for gcc -std=c99
I tried to use the ifc option -C90 but nothing change: I have always the same error type:

"

where the head_, decod_ .. are .c subroutines.

Anybody knows the otption to use to put the underscore in the good place of the subroutine and so do the compatibility between ifc and gcc?

Thanks
