[linuxtools-dev] LTTng question

[Xavier RAYNAUD <xavier.raynaud@xxxxxx>]

Hi,

I tried to play with LTTng plugins (I've checkout the trunk), but up to 
now, I was not able to open any trace.
I followed instructions from documentation (I compiled LTTv application, 
with the JNI support enabled).

Unfortunately, when I open a trace, the following error is written on 
console:

[...]
** (eclipse:32245) DEBUG: Opening file.

** INFO: Error opening tracefile

I guess I've compiled a wrong version of LTTv application ?
Which one should I use instead ?



Many thanks,

Xavier
