I am trying to modify the threads sample application with the following code:
my_sleep_ms=sys_rand32_get();
my_sleep_ms+=sleep_ms;
if (my_sleep_ms > 5000) {my_sleep_ms -= 5000;}
This causes a massive, unintelligible, word salad, error message at build time:

If I modify the code to not include the sys_rand32_get() call as follows:
//my_sleep_ms=sys_rand32_get();
my_sleep_ms=sleep_ms;
if (my_sleep_ms > 5000) {my_sleep_ms -= 5000;}
I builds with no errors an executes correctly.
This leads me to believe I don't have my project set up correctly but I have no idea what to do to fix it. I
s there a maven among you kind enough to lend a hand?
