MATLAB: Am I unable to compile the model when using Microsoft Visual Studio 6.0 with Real-Time Workshop Embedded Coder 4.4 (R2006a)

Embedded Coderrealtime

When compiling my model I receive the following error messages from the linker:

When I use the Microsoft Visual Studio 7.1, the model compiles and links successfully.

This problem results from the use of C++ iostream utilities (in an S-Function) whose libraries are not linked by MSVC 6.0 by default. To prevent the problem, add the corresponding MSVC runtime libraries, which are "libcp.lib" and "msvcprt.lib", to the Custom Code Libraries. To do that:
1) Under "Configuration Parameters" go to "Real-Time Workshop -> Custom Code -> Include list of additional".
2) Put "libcp.lib" and "msvcprt.lib" in the "Libraries" tab, and the corresponding MSVC 6.0 runtime library directory path in the "Include directories" tab.
You should be able to build the model without encountering this problem.
