Matthias,
First of all, thank you for taking your time to help!
I tried specifying the target mcu as you said:
msp430-gcc -mmcu=msp430x2013 -Os -g -C99 -o main.elf main.c CC1100-CC2500.c
TI_CC_spi.c
and I got this error:
Known MCU names:
msp1
msp2
msp430x110
msp430x112
.... ..... .... ....
msp430x2101
msp430x2111
msp430x2121
msp430x2131
msp430x311
msp430x312
..... ..... ....
..... ..... ....
/tmp/cclxRjU8.s: Assembler messages:
/tmp/cclxRjU8.s:2: Fatal error: unknown MCU: msp430x2013
It seems my msp430-gcc does not support the msp430x2013 target. I wonder which
version you have? Here are some details of my compiler and target:
msp430-gcc -dumpmachine
msp430
msp430-gcc -dumpversion
3.2.3

Tamas,
you are really close to success.
Add the
-mmcu=msp430x2013
switch to compiler and linker command lines.
If you don't specify a -mmcu switch, it defaults to msp430x110 which has
to few flash for the code to fit in.
You may ignore the extern warning, or just remove the extern keyword
from lines 104+105 of CC1100-CC2500.c.
char paTable[] = {0x51};
char paTableLen = 1;
Because on these tho lines, the variables are defined and declaring
variables as extern on the lines they are defined does not make sense to me.
I declared the
ISRs as
interrupt (PORT1_VECTOR) port1_ISR (void)
interrupt (PORT1_VECTOR) port2_ISR (void)
the main as
int main (void)
and put a while after the _BIS_SR ...
_BIS_SR(LPM3_bits + GIE); // Enter LPM3, enable
interrupts
while(1) {};
just to get rid of some warnings ...
After above changes, one warning resides:
subscript has type `char' in TI_CC_spi.c line 267, which may be ignored
here.

Good luck!
