Should I upgrade from PCM v3.245
PostPosted: Fri Apr 04, 2008 2:29 pm     Reply with quote
I have several 16F84, 16F876A and 16F877A projects running with code compiled using PCM v3.245. They have all been running fine for over a year now in a production environment.

I need to make some major functional updates to the software and was wondering if I should/need to upgrade to the latest level compiler- v3.249 or v4.071? Are there any significant "bug fixes" in these later versions or just features added?

Thanks.

There were some bug fixes between 3.245 and 3.249. That version is stable and relatively bug free.
Version 4 has a linker, supports bit arrays and in general has a bit of optimization added to many built in routines.
Version 4 also has lot of cosmetic feature additions which are cool if you use the IDE Compiler.

The PCM command line compiler can't create linkable object files:

I think I can stick with v3 for now. Which version is relatively bug free, V2.245 or V3.249?

From the old versions page:
Quote:

3.244 ICD interface updated
3.245 The optimization level was being reduced for some programs, this is now fixed
3.246 A switch() problem resulting in an internal error message for some programs is fixed
3.248 Some poor optimization in 3.246 is now fixed
3.248 Over-allocation of some unions is fixed
3.249 A debugger problem with PIC18 is fixed
