Hello all,
I am getting an Import Error when trying rum sumilation in TOSSIM.
When I do a make micaz sim it successfully builts micaz TOSSIM
library. Though there are two warnings:
/opt/tinyos-2.x/tos/lib/tossim/sim_packet.c:109: warning:
'__nesc_nido_resolve' defined but not used
/opt/tinyos-2.x/tos/lib/tossim/sim_packet.c:119: warning:
'__nesc_nido_initialise' defined but not used
But when I compile this code I get the following error:
Traceback (most recent call last):
File "test.py", line 1, in ?
from TOSSIM import *
File "/opt/tinyos-2.x/tinyos-2.x/apps/tableModule/TOSSIM.py", line
5, in ?
import _TOSSIM
ImportError: /opt/tinyos-2.x/tinyos-2.x/apps/tableModule/
_TOSSIMmodule.so: undefined symbol: sim_mote_start_time
Also, when use gdb I get the following message:
(gdb) make micaz

I am using tinyos-2.0.0beta2-3 (RPM version 4.4.2) installed in
Fedora Core release 5 (2.6.18-1.2257.fc5).
Any idea as to why I am getting these errors. Please help.
If you could send the complete compile output of 'make micaz sim'
that would help.
Something is wrong with the linking when building TOSSIMmodule.so.
For some reason, it isn't linking in the object file that defines
sim_mote_start_time. This is a C linking problem. Looking at the
Makefile should help you figure out what's going wrong. Have you
tried the 2.0 release?
