C code---> sfunction --> Xpc Target with legacy_code

Hi I'm trying to use the legacy code tool to create a s function from C code, that then can be loaded onto a target machine and ran.

I worked through the example on mathworks website:

http://www.mathworks.co.uk/help/simulink/sfg/integrating-existing-c-functions-into-simulink-models-with-the-legacy-code-tool.html

I used the example to create an s function but then attempted to use the model wizard to compile the simulink model into my target machine but it comes up with the error :

S-function 'ex_sfun_doubleit' in 'untitled/ex_sfun_doubleit' specifies option SS_OPTION_SFUNCTION_INLINED_FOR_RTW however a 'ex_sfun_doubleit.tlc' file could not be located in the current working directory, the S-function directory 'C:\Users\HIL\Documents\MATLAB\LEGACY_TEST', or the directory 'C:\Users\HIL\Documents\MATLAB\LEGACY_TEST\tlc_c'

can some one explain ?

What is a "model wizard"?

1. To generate a TLC file for the model shown at the end of that example, enter the following command:

legacy_code('sfcn_tlc_generate', def);

This is from http://www.mathworks.com/help/simulink/sfg/integrating-existing-c-functions-into-simulink-models-with-the-legacy-code-tool.html

2. It is also possible to set SS_OPTION_SFUNCTION_INLINED_FOR_RTW to false in the generated S-Function, but I am not able to remember the option. A google search perhaps....
