[lttng-dev] Issues running ust 2.1.0 as non root user

[Aaron Spear]

Hi all,

I have LTTng 2.1.0 that I built/installed from source, and it all works fine when I run as root.  So as root I can take kernel traces and also ust traces.  However, when I attempt to run UST as a normal user it seems that there is some issue with the session daemon that I am not quite understanding.  It looks like the permissions are correct on the executables in /usr/local/bin and such.  Here is the error that I see with the verbose flag on (not sure if this helps...)

aspear at aspear-deb64 ~
$ lttng --verbose create mytest
DEBUG3: URI string: file:///home/aspear/lttng-traces/mytest-20130111-093135 [in uri_parse() at uri.c:253]

Is there perhaps some other setup step required when you do the install from source that the install does for a normal user?

thanks,
