Hello Folks,
I used to play with TestDip in simulating DIP in TOSSIM. However, when I
downloaded/installed the tinyos VM image(
http://sing.stanford.edu/tinyos/dists/xubuntos-2.1-vm.tar.gz) from the link
of
http://docs.tinyos.net/index.php/Running_a_XubunTOS_Virtual_Machine_Image_in_VMware_Playerin
Windows 7 64bit with VM Player after HDD failure, and I ran it but it
gave me "Segmentation Fault (core dumped)". I have tried to figure this out
for a couple of weeks, but I can't find the solution.
I used to get the log like following.
----
DEBUG (0): Decision to DATA
DEBUG (0): Converting key 7 to index 6
DEBUG (0): Converting key 7 to index 6
DEBUG (0): Data sent with key 5 and version 00010000
DEBUG (0): Attempting to send data in the air
DEBUG (0): Data send successfully in the air
DEBUG (0): Window size requested, give 1024
DEBUG (0): Firing Trickle Event Timer
----
However, now I got the following problem with clean installation of above
image (I used to use above and it worked very well)
------
DEBUG (0): Decision to DATA
DEBUG (0): Converting key 1 to index 0
DEBUG (0): Converting key 1 to index 0
DEBUG (0): Data sent with key 1 and version 00010000
DEBUG (0): Attempting to send data in the air
Segmentation fault (core dumped)
xubun...@xubuntos-tinyos:/opt/tinyos-2.1.0/apps/tests/TestDip$
-------
It looks got this issue right before sending a message (from app.c).
-----------------app.c
#line 42
sim_log_debug(177U, "AMDipP", "Attempting to send data in the air\n");
err = AMDipP$NetAMSend$send(AM_BROADCAST_ADDR, &AMDipP$am_msg[sim_node()],
len);
if (err == SUCCESS) {
AMDipP$busy[sim_node()] = TRUE;
}
return err;
}
------------------------
As Preeti said in the mailing list, I added one more flag (-shared) in
PLATFORM_BUILD_FLAGS like this
PLATFORM_BUILD_FLAGS= -fpic *-shared* -W1,--enabled-auto-image-base
As Phil said
"*Segmentation faults:* If trying to do this causes TOSSIM to throw a
segmentation violation (segfault), then chances are you are using a version
of gcc that does not work well with the dynamic linking that TOSSIM is
doing. In particular, it has been verified to work properly with 4.0.2 and
3.6, but some people have encountered problems with gcc 4.1.1. " in
http://docs.tinyos.net/index.php/TOSSIM.
I checked my environment like following, but I can't get resolved.
Could you tell me what's wrong with this? Or can you tell which VM has no
issue like above?
