Unhappy ARToolKit


Hello to everybody,
I'm a new ubuntu 12.04 (64-bit) LTS user. In these days i'm having a lot of problems trying to install ARToolKit for markers detection(the topic of my master thesis work). I followed a lots of guide to install it:

http://www.hitl.washington.edu/artoo...serstartup.htm

http://www.linuxforums.org/forum/ubu...-x86_64-a.html

Unfortunately nothing worked.

I attach you the error of the second guide i followed(http://www.linuxforums.org/forum/ubu...-x86_64-a.html)

marcello@marcelloPC:~/ARToolKit/ARToolKit/bin$ ./simpleTest
No video config string supplied, using defaults.
libARvideo: GStreamer 0.10.36

(simpleTest:8971): GStreamer-CRITICAL **: gst_parse_launch_full: assertion `pipeline_description != NULL' failed
Segmentation fault (core dumped)

I waste last three days but i cannot solve this problem.

Can anybody help me??

Thanks for your reply,finally i solved that problem,but there is a new one now
This morning i started with this tutorial:
http://www.hitl.washington.edu/artoo...n/devmulti.htm

The problem is that after build my marker i cannot train the pc on that marker.
In that guide i should do:
./mk_patt
Enter camera parameter filename: (i put the path of file camera_para.dat)

I receive this answer:
Usin supplied video config string [videotestsrc].
libARvideo:GStreamer 0.10.36
(mk_patt:5146):Glib-GObject-WARNING**:invalid cast from 'GstVideoTestSrc' to 'GstBin'
(mk_patt:5146):GStreamer-CRITICAL **:gst_bin_get_by_name:assertion 'GST_IS-BIN (bin)' failed
pipeline has no element named 'artoolkit'!
setupCamera():Unable to open connection to camera.
main():unable to set up AR camera

I hope you have a solution for this problem!!!
Thanks for your help
