OK. Let's make this more clear: anyone has a working 8-2-PRERELEASE kernel
(amd64
is preferred) with Dtrace supports, which can run the scripts/commands on the
wiki? If so, please post your kernel configurations here, thanks.
Not sure about commands on the wiki, but DTrace works perfectly with my scripts.
$ uname -srm
FreeBSD 8.2-PRERELEASE amd64
It's actually built from r216118 sources.
$ dtrace -n 'fbt::sc_switch_scr:entry { printf(%p\n, args[0]); }'
works without any issues.
My kernel has the same DTrace related options as the wiki page:
options KDTRACE_HOOKS # all architectures - enable general
DTrace hooks
options DDB_CTF # all architectures - kernel ELF linker
loads CTF data
options KDTRACE_FRAME # amd64-only
Here's how I built and installed the kernel:
$ make buildkernel WITH_CTF=1
$ make installkernel
KERNCONF is set my kernel's name in /etc/make.conf.
Not sure what kind of an issue prevents you from using DTrace, double-check all
your steps.

I followed the instructions, but still can not run any D-scripts.
All
scripts shows the error message that I just posted.
Are the installed world and the installed kernel in sync?
(Built from the same state of source code).
The same question.
FWIW, I can reproduce his problem when following the procedure outlined
in the Wiki.
As a workaround I tried adding WITH_CTF=true to /etc/src.conf and
rebuilding + reinstalling world + reboot, to no avail. I'm rebuilding
the kernel now to see if that makes a difference after the above
workaround.
Nope, no go.

The text that it will not work in make.conf/src.conf is valid for 8.x, but not (at least it shouldn't) for an appropriate versions of 9-current. My interpretation of what Alexander wrote is this: On RELENG_8, the WITH_CTF=1 parameter must be specified manually on the command-line during the buildworld/installworld and buildkernel/installkernel phases, and cannot be put into /etc/src.conf or /etc/make.conf. E.g.: make buildworld WITH_CTF=1 make buildkernel WITH_CTF=1 make installkernel WITH_CTF=1 make installworld WITH_CTF=1 I'm sure one (or more) of these is superfluous, but someone needs to state up front what exactly the proper procedure is. The makeoptions WITH_CTF=1 kernel configuration option doesn't appear to work on RELENG_8, and I can confirm that WITH_CTF=true in /etc/src.conf might do something but it doesn't fix the problem reported originally. Someone should also probably update the Wiki to reflect what does work properly on RELENG_8 and have a separate section for CURRENT/9. -- | Jeremy Chadwick j...@parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.

Re: Fwd: Re: Fail to use Dtrace on FreeBSD 8.1-STABLE
As I posted in another email, the gcc crashes in latest RELENG_8. Another explanation is that buildworld WITH_CTF=1 can crashes the gcc. I overwrote the gcc with the version in 8.1_RELEASE, and I'm rebuilding everything. I just want to know whether I'm supposed to be able to use Dtrace just with a CTF-enabled kernel. And, if so, what should I do to make it actually works. Thanks... guys. On Tue, Nov 23, 2010 at 4:50 PM, Zhihao Yuan lich...@gmail.com wrote: Can not rebuild kernel.

Re: Fwd: Re: Fail to use Dtrace on FreeBSD 8.1-STABLE
I'm sorry, I'm not going to split the topics. So here is the current status: built kernel WITH_CTF and build world without CTF (I assume CTF is just a kernel feature). And the problem is exactly the same as I posted before, say line 88 staff. And, there are many people who have the same problem. Is it caused by some other options in our KERNCONF? Or it just does not work on some platforms On Tue, Nov 23, 2010 at 11:28 PM, Jeremy Chadwick free...@jdc.parodius.comwrote: On Tue, Nov 23, 2010 at 10:20:52PM -0600, Zhihao Yuan wrote: As I posted in another email, the gcc crashes in latest RELENG_8.
