Everyone, By the way, even though I forgot to include #math.h in my minimal example, this does not make a difference, identical results with this version:
/* minimal program showing math linking problems */ #include <math.h> int main(void) { float a,b,c; a = 1.234; b = 5.678; c = pow(a,b); return 0; } W:\msp430\stack-code>msp430-gcc -g -mmcu=msp430x149 -o2 -lm fptest.c -o fptest.elf /cygdrive/c/DOCUME~1/torfst/LOCALS~1/Temp/ccZtdM8k.o(.text+0x2e): In function `main': /cygdrive/w/msp430/stack-code/fptest.c:11: undefined reference to `pow' greetings, Tom
