[Ovmsdev] Problem building the project

I've done the same.

The problem is code size. The linker map produced shows that the code built is 3 to 5 times the size it should be.

For example, .code_crypt_md5 on my mac is 0x001a98 bytes in size. On my PC it is 0x5ec6.
And .code_vehicle_twizy on my mac is 0x002cd8 bytes in size. On my PC it is 0x48b2.

Looks like the optimisations are not working, or getting enabled.

I'm now trying to find out why...

Regards, Mark.

Some adjustment will be done automatically on building to find a working compiler, but I wouldn't rely on that to be complete. Also restarting MPLAB after that first config change might be necessary, I had to do that a few times (but on other errors).

But, it seems that the mcc18 compiler can't handle rom based pointers to code anyway, so auto-changes them to ram based variables for us (which is why we never noticed the problem before). I don't think this is your problem, but perhaps you could try to change the "rom BOOL (*vehicle_fn_*" definitions in vehicle.h and vehicle.c to just "BOOL ..." (ie; without the ROM prefix) and see if that fixes anything.
