The exact error message you're getting would be helpful. I'm guessing
it's actually this message, with %s replaced by the name of the signal:
"HAL: ERROR: insufficient memory for signal '%s'\n"
is that correct?
If so, you're probably also bumping the limit on the hal shared memory
segment. You can see the amount available at any time with a 'status'
command. Insert it just above the failing line, and then have a look at
the output.
Here with nothing loaded, I get:
$ halcmd status
HAL locking status:
current lock value 0 (00)
HAL_LOCK_NONE - nothing is locked
HAL memory status
used/total shared memory: 264/262000
active/recycled components: 1/0
active/recycled pins: 0/0
active/recycled parameters: 0/0
active/recycled aliases: 0/0
active/recycled signals: 0/0
active/recycled functions: 0/0
active/recycled threads: 0/0
If you've reached the limit, then you can increase it by modifying the
#define HAL_SIZE directive in hal_priv.h, then rebuilding, like so:
diff --git a/src/hal/hal_priv.h b/src/hal/hal_priv.h
index 1ef1f74..b0550d0 100644
--- a/src/hal/hal_priv.h
