CodeWarrior __MWERKS__ defined ?

[SylvainBortelle]

Hello,

I have created a new project with the wizard of CW, and i need to know if this variable : __MWERKS__ is defined by default when we use CodeWarrior.

Thank you for your help.

Hello

- Which CPU are you targeting (HC08, HC12, Coldfire, ..)
- Which version of CodeWarrior are you using?

     To retrieve that info (For version number smaller than 10.0):
       - Start CodeWarrior
       - Select Help -> About Freescale CodeWarrior
       - Click on "Install Products"
      - CodeWarrior version used is displayed on top in the Installed Products dialog.

     To retrieve that info (For version number 10.0 and higher):
       - Start CodeWarrior
       - Select Help -> About CodeWarrior Development Studio

- Version and build number are indicated under "Installed Products" section.

Hello

  Did you look at the {Install}\help|PDF\Power Architecture Build Tools Reference.pdf manual.

  It says:

" __MWERKS__
Deprecated. Preprocessor macro defined as the version of the CodeWarrior compiler.

Syntax
__MWERKS__

Remarks
Replaced by the built-in preprocessor macro __CWCC__.
CodeWarrior compilers issued after 1995 define this macro with the compiler’s version. For example, if the compiler version is 4.0, the value of __MWERKS__ is 0x4000.

This macro is defined as 1 if the compiler was issued before the CodeWarrior CW7 that was released in 1995."

Note

A quick way to check whether the predefined macro is defined is to add following code to one of your application source file:

#ifdef __MWERKS__   #error "Test macro"#endif

Then try to build this file. If the predefined macro is defined you will get a message

         "preprocessor #error directive"

I hope this helps
