11 xPC Target and Fortran

Invoking the mex command includes the following steps:

1 Compile the wrapper C file sfun_atmos.c. Be sure to link in the following:

- Compiled wrapper file:

sfun_atmos.obj

- Compiled Fortran code: sfun_atmos_sub.obj

- Necessary Fortran run-time libraries to resolve external function

references and the Fortran run-time environment

2 Type

mex -v LINKFLAGS#"$LINKFLAGS dformd.lib dfconsol.lib

dfport.lib" sfun_atmos.c sfun_atmos_sub.obj

Ensure that this whole command is all on one line. This command compiles

and links the

sfun_atmos_sub.c file. It creates the sfun_atmos.dll file in

the same directory.

Note If this command generates a conflict error with libc, you might need to

add the option

/NODEFAULTLIB:libc.lib to the command. For example, mex

-v /NODEFAULTLIB:libc.lib LINKFLAGS#"$LINKFLAGS dformd.lib

dfconsol.lib dfport.lib" sfun_atmos.c sfun_atmos_sub.obj.

Your next task is to validate the Fortran code and wrapper S-function. See

“Validating the Fortran Code and Wrapper S-Function” on page 11-10.

Validating the Fortran Code and Wrapper

S-Function

Validate the generated DLL, sfun_atmos.dll. Bind the S-function DLL to an

S-function block found in the Simulink block library. You can mask the

S-function block like any other S-function block to give it a specific dialog box.

This section assumes that you have compiled and linked a wrapper S-function.

See “Compiling and Linking the Wrapper S-Function” on page 11-9.

The Atmosphere model example has a Simulink model associated with it.
