HELP!Error :NO child processes in LTTV (linux trace toolkit viewer)
- From: "hide1713@xxxxxxxxx" <hide1713@xxxxxxxxx>

Error message comes when i press START button in lttv-gui :No child
processes
and another message show : No such file or directory when pressing the
STOP
I successfully patched the kernel and compiled Lttng following the user
guide. The thing i feel strange is that i can't find ltt-core and
ltt-relay modules but i thouht they were built in kernel.
This is the error message.
