I have problem compiling a asm fil in my msp-gcc project. The #define

If I replaces &P1OUT with 0x0021 in the code it will work! This shuld
not be a big problem...
you may need to specify "-x assembler-with-cpp" and use gcc to call as:
msp430-gcc -x assembler-with-cpp -D_GNU_ASSEMBLER_ -mmcu=msp430x1121
-c file.s -o file.o
also note that you'd define _GNU_ASSEMBLER_ on the command line and not
in the file itself. that way you can write files that work with c and
assembler.
then you can include io.h and have all the defines from the compiler, no
need to do it by hand..
for an example using asm + c and a makefile:
