Hi All, I just ran into an issue and am wondering if I am missing something. main.c implements int main(void) foo.c implements void blink(void) main() calls blink() main.c and foo.c are compiled like so: msp430-gcc -c -mmcu=msp430g2452 -g -Os -Wall -Wunused -IInclude -o main.o main.c msp430-gcc -c -mmcu=msp430g2452 -g -Os -Wall -Wunused -IInclude -o foo.o foo.c Test 1: If I link main.o and foo.o with msp430-gcc main.o foo.o -mmcu=msp430g2452 -Wl,-Map=hello.map -o hello.elf all is blinky blinky. Test 2: when I create an archive core.a that holds foo.o with: msp430-ar rcsv core.a foo.o and then link the final elf file with: msp430-gcc core.a foo.o -mmcu=msp430g2452 -Wl,-Map=hello.map -o hello.elf All again is blinky blinky. Test 3: The problem surfaces when I create an archive core.a that holds main.o with: msp430-ar rcsv core.a main.o and then link the final elf file with: msp430-gcc core.a main.o -mmcu=msp430g2452 -Wl,-Map=hello.map -o hello.elf All is dark. I ran the same test with a simple "hello world" compiled for x86 using gcc and ar under cygwin and all is fine in all 3 cases. Any idea why this does not work for msp430? I looked at the linker scripts but that only resulted in more darkness. Regards, Robert Wessels
