Using C++ with coldfire MCUs

[High_Templar]

Hi all.

I'm trying to make a C++ project for the TWR-CN128 (coldfire MCU). However, when I add a simple class, the compiler give me this error: undefined identifier 'class'. I don't get this error when I use a S08 or Kinetis MCU .

I'm using CW 10.3 Special Edition.

Thanks for any help.

Hi angel,

the special edition does not include C++ support. The S08 has a 1 KByte free limit, while while the ColdFire compiler allows 0 bytes (it compiles the C++ files as a C file).

Kinetis: I think you used the gcc option: here the compiler/linker has no limitatin (as GNU). The debugger will impose the limitation. So for ColdFire, you either upgrade your license, or you could consider gcc for ColdFire.

Hi Erich.

Thanks for you answer. Making some testing with #warnings, I realize what you say: the cpp file is compiled in C mode (and that using a eval license, the file compile with no errors)

:smileysad:

Well, I will investigate how to use gcc for coldfire.

Thanks!
