| [linuxtools-dev] Question about issue with loading an LTTng trace |
|
Hi guys, I have a question about trace reading libraries and
compatible versions. I have Helios SR2 linuxtools installed, and followed
the instructions on the wiki to build the latest snapshots of both the 2.5 and
2.6 trace libraries and installed them. With the Eclipse viewer I
can import and analyze the trace-15316events_nolost_newformat.tar.gz example
data that I downloaded from a link in the help with no issue, it looks great. I then followed instructions I found here https://launchpad.net/~lttng/+archive/ppa
to install pre-built kernel packages for lttng for an Ubuntu 10.10 32 bit
Linux. I can successfully dump/analyze traces that I collect using
lttv and lttv-gui. Awesome that this package is available btw, very
cool. If however I try to open these traces with the Eclipse
viewer I get no visible error that I can discern but see the exception below in
the console which spawned eclipse. Does anyone have any idea what might
be wrong? Incorrect version? Again, I can successfully load the
demo data mentioned about with the viewer, but it appears that this data is 2.5
format from comments that I read. I am not sure if I can successfully read
2.6 data or not… If you are interested, you can get the trace at http://www.ontherock.com/trace7.tar.gz Thanks for any guidance, Aaron -------------------- joe@ubuntu:~/tools/eclipse-linuxtools-helios-SR2-incubation-linux-gtk/eclipse$
