Hi guys !
I have some problems to install the LTTv library for Eclipse. I am
following the instructions in the help contents page. I have downloaded
the last lttv source master from the git repository
(http://lttng.org/cgi-bin/gitweb.cgi?p=lttv.git;a=summary -> Mon, 4 Jan
2010 18:53:58).
When I make, I get this error :
jni_interface.c: In function
'Java_org_eclipse_linuxtools_lttng_jni_JniTracefile_ltt_1pri ntTracefile':
jni_interface.c:504: erreur: structure n'a pas de membre nommé « buf_size »
Which version of the repository I must compile to get the lttv in Eclipse ?
Thanks a lot.
Fred

Hi Francois,
I succeed in installing the liblttngtrace.
I have now a second problem. When I click on the experiment folder I
have this exception in eclipse :
** (Eclipse:4154): WARNING **: Unsupported trace version : 2.3
** (Eclipse:4154): WARNING **: parse_trace_header error
** (Eclipse:4154): WARNING **: Trace
Test_trace/Traces/trace-618339events-1293lost-1cpu has no metadata tracefile
org.eclipse.linuxtools.lttng.trace.LTTngTraceException: Error while
opening trace. Is the tracepath correct? (openTrace)
at
org.eclipse.linuxtools.lttng.trace.LTTngTrace.<init>(LTTngTrace.java:116)
at org.eclipse.linuxtools.lttng.trace.LTTngTrace.<init>(LTTngTrace.java:97)
Do you have a trace example that it's working with the liblttngtrace and
the last eclipse repository ?
Best regards.
Frédéric
