Hi,
I'm trying to get eclipse to show the lttng trace...
Can anyone tell me which version of liblttvtraceread lib I need to get
older trace to come up?
I'm trying to display traces for target kernel 2.6.16.9
with following lttng components installed
patch-2.6.16-lttng-0.5.69.tar.bz2.
ltt-control-0.10-12062006
ltt-usertrace-0.12
userspace-rcu-0.5.4
ust-0.12
LinuxTraceToolkitViewer-0.8.47-12062006
When I open a trace I get the following
exception (I downloaded/compiled/installed the latest version of the
trace reader, which I guess isn't the right thing to do in this case):
--Mike
FedoraBox liblttngtrace-7298415]$
org.eclipse.linuxtools.lttng.trace.LTTngTraceException:
ERROR : Unrecognized/unsupported trace version.
Library reported a trace version 200.113.
Make sure you installed the Lttv library that support this version
(look for liblttvtraceread-200.113.so).
According to the compatibility list[1], LTTng version 0.5.69 outputs the
trace format version 0.7, which is only supported by really old versions
of LTTV. The Eclipse TMF viewer only supports versions 2.3, 2.5 and 2.6
. (Funny that it reports "200.113")
However, traces generated by UST are all in the 2.6 format, so those
would be viewable in Eclipse.
