Problems with Static Library

[cesarpradosboda]

Hi,

I want to make a small program that uses a static library made in FORTRAN&C, to see how the calls work from Fortran to functions made in C when I want work whit Build Environment for IA-32 applications, the source of the program it's described next, if I use the Fortran command prompt, I am able to do it, but if I want do it from Microsoft IDE to develop, I obtain the next error:

Console1 error LNK2019: unresolved external symbol _WRITE_HELLO referenced in function _WRITE_SM()

The first step that I have make is a Project where I've made the library. In this work area there are two projects, one for the fortran files and and another one for the C files. I have configured of following form the PROPERTY PAGES:

FORTRAN/EXTERNAL PROCEDURES:
Calling COnvention-->Default
FORTRAN/LIBRARIES
Disable Default Library Search Rules--> No

The second step to do is the link the lib to the main program.

I've did "Add existing item-->prog.lib"

FORTRAN/EXTERNAL PROCEDURES:
Calling COnvention-->Default
FORTRAN/LIBRARIES:
Disable Default Library Search Rules--> No

Result-->error LNK2019
If I change the next property:
LINK/INPUT:
Additional Dependecies-->prog.lib
Result-->
Console1 Fatal error cannot open "libra.lib"
Console1 error: problem during multi-file optimization compilation (code 1)

what is it wrong in the Properties? Code:

LIBRARY
Code:Lib_c_64.h
#include 
#include 
#include 
#include 
#include 

int write_hello();

Prog_c_64.c

#include "Lib_c_64.h"
int write_hello()
{
printf("Ciaooooooo");
return 0;
} 

 Prog.f90

SUBROUTINE WRITE_SM()

INTERFACE 
INTEGER FUNCTION WRITE_HELLO()
!DEC$ ALIAS:'_write_hello'::write_hello 
END FUNCTION
END INTERFACE 

INTEGER IO

IO = write_hello()

RETURN
END SUBROUTINE WRITE_SM

Thanks in advance
