systemtap process probes requires CONFIG_UTRACE enabled

[Tais P. Hansen]

Attempting to perform systemtap process probes with latest maverick kernel results in an error similar to the following:
semantic error: process probes not available without kernel CONFIG_UTRACE while resolving probe point process("6997").end
Pass 2: analysis failed. Try again with another '--vp 01' option.

This also prevents profiling, call graphing and similar to work on C/C++ code in IDEs like Eclipse and other using systemtap for profiling.

I have this problem too

[Sergey K (koblin)]

the same problem exist in natty 11.04 :-(

[ckluss (ckluss-7)]

Hi,

I have this problem too. I want to use "Linux Tools Project/Callgraph" http://wiki.eclipse.org/Linux_Tools_Project/Callgraph/User_Guide that requires systemtap with utrace support.

Perhaps the following solves the problem, but leads to new problems...

sudo add-apt-repository ppa:speijnik/utrace-kernel

sudo apt-get install linux-headers-2.6.35-26 \
         linux-headers-2.6.35-26-generic-pae \
         linux-tools-2.6.35-26

Is there a better way to bypass this problem?

[Sergey K (koblin)]

guys! we need only one option (CONFIG_UTRACE) in kernel config to resolve this bug! please =)

[Sergio Rubio (rubiojr)]

Looks like the config option is also missing in 3.2.0-8-generic from Precise

[Timo Juhani Lindfors (timo-lindfors)]

Sergey, utrace support is not mainline. you need to patch your kernel before you can even select that option.

[tlaurion (thierry-laurion)]

See here. http://sourceware.org/systemtap/wiki/SystemtapOnUbuntu

Also have this problem in Ubuntu 12.04 Server, the ubuntu 3.2 kernel .config seems do not have this flag. I just upgrade to the new version.
