Hi Naresh,

Ok, the versions you are using should be compatible. But it's possible
LTTv is using wrong versions of the trace reading library that may have
remained from previous installs. Can you post the output of " ls -l
/usr/local/lib/liblttv* " ?


An alternative would be to update to a more recent version. You
mentioned in your previous email you are using kernel 2.6.32.21.  You
should be able to patch it with LTTng version 0.198 without too much
problems.
http://lttng.org/files/lttng/patch-2.6.32.9-lttng-0.198.tar.bz2

This will generate patches using the trace format 2.6. You could then
use lttctl 0.87 and LTTV 0.12.36. Make sure you "make uninstall" the old
versions before installing those.
