[lttng-dev] Issue with UST tracing - unable to view CTF traces

[Jonathan Haws]

I am having a problem with UST tracing on my system.  My setup is as follows:

I have my development system running Xubuntu 12.04 LTS with the LTTng ppa enabled, so I am running the 2.4.0 tools.  I have my embedded target running manually compiled 2.4.0 tools (it's distro is Fedora 17 right now).

Last week things were working just fine, but I made some changes to my template file and something broke, but I can't figure out what is up.


When I try to import traces into the Eclipse tools, I get the following error:

org.eclipse.linuxtools.tmf.core.exceptions.TmfTraceException: MismatchedTokenException(LPAREN!=TERM) at metadata:204


When I try to open with babeltrace, I get the following:

jhaws at verde:~/trace$ babeltrace sms/SMS-20110922-130857/ust
[error] at line 199: token "(": syntax error, unexpected LPAREN, expecting SEMICOLON or COMMA

What am I doing wrong?  Things were working great before, but now something is up. What are the chances that there is a compatibility issue between the two installations?

Thanks!
