[ltt-dev] Problems in modprobe [ FATAL : Module not found ]

[ltt-dev] Problems in modprobe [ FATAL : Module not found ]

[soumyakanti chakraborty]

Hi All

This is my first mail to the list, so a quick introduction. I am *Soumya
Kanti Chakraborty* currently pursuing MS degree at Mdh (Malardalen
University), Sweden.

From the last few days and nights I am trying to Install LTTng in my Ubuntu
9.10. After much efforts and recompiling today all the configurations went
right and my kernel booted successfully. But after activating DebugFS when I
started to modprobe for all the modules (as directed in the manual), I found
the same error for each [ FATAL : module not found ]. When I see the path *
/lib/modules* there is also no modules for LTTng. As what I remember during
the *make menuconfig *I selected all the LTTng parts to be included inbuilt
in kernel and not build as "*M*" or modules.* *I will be attaching my config
file for reference.

Kernel Version used - *2.6.30*
LTTng patch - *0.159*

I read somewhere in your earlier mailing list threads "*
http://lists.casi.polymtl.ca/pipermail/ltt-dev/**2009**-April/**001470**
.html*"
that if you "have compiled those modules built into your kernel, so in that
case you don't need to load them as module."
*
*
So I just wanted to know can I move forward with installing LTTV and control
packages even if modprobe can't find the LTT modules ?

Here is the link of the config file - http://pastebin.ca/1763957


Thanks and Regards,

Yep, as you see, in your config:

CONFIG_LTT=y
CONFIG_LTT_FILTER=y
CONFIG_HAVE_LTT_DUMP_TABLES=y
CONFIG_LTT_RELAY_ALLOC=y
CONFIG_LTT_RELAY_LOCKLESS=y
# CONFIG_LTT_RELAY_IRQOFF is not set
# CONFIG_LTT_RELAY_LOCKED is not set
CONFIG_LTT_SERIALIZE=y
CONFIG_LTT_FAST_SERIALIZE=y
CONFIG_LTT_TRACEPROBES=y
CONFIG_LTT_TRACE_CONTROL=y
CONFIG_LTT_TRACER=y
CONFIG_LTT_ALIGNMENT=y
CONFIG_LTT_CHECK_ARCH_EFFICIENT_UNALIGNED_ACCESS=y
# CONFIG_LTT_DEBUG_EVENT_SIZE is not set
CONFIG_LTT_USERSPACE_EVENT=y
CONFIG_LTT_VMCORE=y
CONFIG_LTT_STATEDUMP=y
CONFIG_LTT_KPROBES=y
# CONFIG_LTT_ASCII is not set
CONFIG_HAVE_IMMEDIATE=y
CONFIG_IMMEDIATE=y

LTTng is built into your kernel, so you must skip the modprobe step.

After installing ltt-control and lttv, don't forget to run ldconfig (or
reboot), so the libraries get listed.

Enjoy :-)
