simple build steps for me? I see others are building it ok so I am obviously missing something. Perhaps the build steps could be put on the wiki too? That would be great. (Also a link to the wiki from the mspgcc website would be good but I am not going to hold my breath). Thanks! - Wayne Uroda

Re: [Mspgcc-users] multiple definition of ...

If the header file is included in multiple C files, this is why you are seeing the multiple definition error. It is more correct to put the definition in one C file only, then put a declaration in the header file: Strings.c: const char AverageCurrentDisp[] = Bat Avg Current; Strings.h:

Re: [Mspgcc-users] problem converting signed shortto abs unsigned long

According to the C standard, when you apply the unary operator - to x, x is first promoted to an integer. I think the difference between the PC and the MSP430 is that on the MSP430, the variable is promoted to 16bits which is the same size as the short. On the PC, x is first promoted to 32bits.
