Support for Exception in IAR Embedded Workbench

Development Boards MicroMod
1

Colleagues,

I’m trying to use exceptions in Embedded workbench. But this line of code:

throw Exception(FACILITY_I2C, ERR_ERROR); // Exception(...) is a custom class

Generates this compile-time error:

Error[Pe540]: support for exception handling is disabled

Can the support for exceptions be enabled? If so, then how?

Cheers,

  • Nick

Resolution: EWARM supports Embedded C++, which is a subset of C++ that doesn’t have exceptions.

Update: IAR promises that the next version of EWARM, which is scheduled for Feb 2010 will have a fully implemented C++.

I'm evaluating IAR and Keil, if you're asking about compilers. I've downloaded evaluation versions for both of them (EWARM 5.11 and uVision4) and I'm using them for a real R&D project. Initially i was in favor of IAR. Keil, however, is emerging as a winner. I will post my comparison some time soon.

My inner void.

I evaluated in depth Keil, IAR, GCC/Rowley, GCC/YAGARTO, ImageCraft.

I chose IAR and have been using it for a year, for ARM7. I’ve pleased and the phone Q&A (West Coast) has been fine.

I just preferred IAR’s IDE/quick learning curve, ease of use, J-Link flash breakpoint transparency. C99 support. Reasonable price.

Keil is probably a good choice too.
