This is a follow-on to a previous discussion, which discussion quickly
drifted into language-lawyering:

I am trying to use the msp430 simulator built into gdb and am having
trouble getting anywhere.
I'm using Ubuntu 12.04 and the msp430 tools from the repository. (I think
they're actually from Debian.)
I've made the following test program:
volatile int a=0;
int main(void) {
while (1)
a++;
}
Now I want to load it into the simulator, and watch "a" change.
I compile it like so;
$ msp430-gcc --version

$ msp430-gcc -o test.elf test.c
And load it into gdb like so:
$ msp430-gdb test.elf

Well, that is unhelpful. Maybe I'll try with an older version of
msp430-gdb.

OK, how about the Java MSP430 simulator "mspsim"?
$ make run
java -classpath
"build/:lib/jcommon-1.0.14.jar:lib/jfreechart-1.0.11.jar:lib/jipv6.jar:lib/json-simple-1.1.1.jar"
se.sics.mspsim.Main
Usage: se.sics.mspsim.platform.sky.SkyNode <firmware>
make: *** [run] Error 1
No problem, I'll just run the thing myself and supply the executable as
argument.
$ java -classpath
"build/:lib/jcommon-1.0.14.jar:lib/jfreechart-1.0.11.jar:lib/jipv6.jar:lib/json-simple-1.1.1.jar"
se.sics.mspsim.Main ~/hello_msp/test.elf
MSPSim does not currently support the platform 'elf'.
Ah, that's going to be a problem.
Does anyone have other ideas for me to try?

Mark
