[lttng-dev] make a trace_event in a modul (driver)

[Klaus Dannecker]

Hi,
I want to write a driver with trace events.
In the first step i compile the example  trace-events-sample.c with the 
makefile:

ifneq ($(KERNELRELEASE),)
     obj-m  := modul_trace-events-sample.o
     modul_trace-events-sample-y := trace-events-sample.o
     ccflags-y := -I$(src)
else
     KDIR ?= /lib/modules/`uname -r`/build
default:
     $(MAKE) -C $(KDIR) M=$$PWD
endif

now i get the modul_trace-events-sample.ko File.
now:
insmod modul_trace-events-sample.ko
lttng create
lttng enable-event -k -a
lttng start
...wait...
lttng stop
lttng destroy

now i look the result in the eclise viewer, but i found event 
"trace_foo_bar" not in the session!
what am I doing wrong?

I use ubuntu 13.04 in a vmware

Thanks
