MSP430-GCC-OPENSOURCE: GDB Command Exception

MSP430-GCC-OPENSOURCE: Errors Building MSP430 GCC in SlickEdit

Part Number: MSP430-GCC-OPENSOURCE
Other Parts Discussed in Thread: MSP430FR2675, MSP430WARE

I'm getting an "undefined reference to `WDTCTL`" error when I try to build a simple hello world project for MSP430 GCC in SlickEdit, even though I have __MSP430FR2675__ defined.  My source, makefile, and build output follow.  Any ideas?

#include <stdio.h>
#include "msp430.h"

int main (void)
{
// Stop watchdog timer to prevent time out reset
WDTCTL = WDTPW + WDTHOLD;

for (int i = 0; ; ++i) {
printf("Hello world!\n");
}

return 0;
}

    I have no idea what SlickEdit is but defining a symbol is not the usual way of telling GCC which device you are using. Use -mmcu= instead. As in:

    make -k 
/usr/ti/gcc/bin/msp430-elf-gcc -g -mmcu=msp430g2253 -I /usr/ti/gcc/include  -Wall  -Wl,--gc-sections timer.c

    Symbols for special function registers like WDTCTL are defined in the linker scripts. Since you didn't tell the compiler which device you are using, it is no surprise that this symbol wasn't resolved. See slau646 for more information on using GCC for the MSP430.
