Getting ready

The code sample for this recipe is in Fortran and C, setting the stage for Chapter 9, Mixed-language Projects, where mixed-language programming will be discussed. The main program is a simple Fortran executable that calls a C function, print_info(), which will print the configuration information. It is worth noting that with Fortran 2003, the compiler will take care of name mangling (given a proper interface declaration of the C function), as seen in the simple example.f90 source file that we will use:

program hello_world  implicit none  interface    subroutine print_info() bind(c, name="print_info")    end subroutine  end interface  call print_info()end program

The print_info() C function is defined in the template file, print_info.c.in ...
