Real-Time Windows Target

Third Party C Compiler

The Real-Time Windows Target requires one of the following C compilers not included with the Real-Time Windows Target:

• Microsoft Visual C/C++ compiler -- Version 5.0, 6.0, or 7.0.
• Watcom C/C++ compiler -- Version 10.6 and 11.0. During installation of your Watcom C/C++ compiler, be sure to specify a DOS target in addition to a Windows target to have the necessary libraries available for linking.

After installation, run the MEX utility to select your compiler as the default compiler for building real-time applications.

Selecting a Default C Compiler

Real-Time Workshop uses the default C compiler to generate executable code, and the MEX utility uses this compiler to create MEX-files.

Use this procedure to select either a Microsoft Visual C/C++ compiler or a Watcom C/C++ compiler before you build an application. Note, the LCC compiler is not supported:

1. In the MATLAB window, type

• mex -setup
  

1. MATLAB displays the following message:

   • Please choose your compiler for building external interface 
     (MEX) files. Would you like mex to locate installed 
     compilers?([y]/n):
     

2. Type

• y
  

1. MATLAB displays the following message:

   • Select a compiler:
     [1] : WATCOM compiler in c:\watcom
     [2] : Microsoft compiler in c:\visual
     [0] : None
     Compiler:
     

3. Type a number. For example, to select the Microsoft compiler, type

• 2
  

1. MATLAB displays the message:

   • Please verify your choices:
     Compiler: Microsoft 5.0
     Location: c:\visual
     Are these correct?([y]/n)
     

4. Type

• y
  

1. MATLAB resets the default compiler and displays the message:

   • The default options file:
     "C:\WINNT\Profiles\username\Application 
     Data\MathWorks\MATLAB\mexopts.bat" is being updated.
