CodeWarrior 10 Macro Redefined Compile Error

[jimfell]

I'm migrating a CodeWarrior classic project to CodeWarrior 10, and I'm having a little trouble getting the ported project to compile.  I did use the CodeWarrior Classic Project Importer, and the import wizard seemed to successfully complete.

After creating a new header file for the symbols that were defined in the CW Classic Preprocessor project settings, I set that file as the ColdFire Compiler Input Prefix File in the CW10 project settings.  Compiling the project yielded the following macro redefinition error:

=#define _MSL_OS_TIME_SUPPORT 1

>macro '_MSL_OS_TIME_SUPPORT' redefined

"C:/Program Files/Freescale/CW MCU v10.2/MCU/ColdFire_Tools/Command_Line_Tools/mwccmcf" @@"Sources/main.args" -o "Sources/main_c.obj" "C:/[PROJECT DIR]/Sources/main.c" -MD -gccdep

What gets me is the references to the command-line definitions.  _MSL_OS_TIME_SUPPORT is defined in the new header file previously mentioned.  I don't see anywhere in the CW10 project settings where this macro would be getting defined.  Any help would be appreciated.  Thanks.

Hello

The prefix file you are using to build your application is specified in Project Properties  C/C++ Build > Settings > ColdFire Compiler > Input page, in field Prefix File.

Additional macros can be defined on the command line in Project Properties  C/C++ Build > Settings > ColdFire Compiler > Language Settings page, in field Other flags.

The macro redefinition warning might also be generated because the file 410-2011rOBDMain.h is included several times.

Can you try to add following line to your prefix file:

    #pragma once on

This should prevents header files from being processed more than once.
