Re: stptracer-20060828 has released.

Hiramatsu san,
I'd like to try this release, but found a problem when starting it.
The problem is :
Although i configured kernel with RELAY option, it find relayfs is not
in kernel or not built.  Then, it triggers to build relayfs provided
by systemtap runtime.  But the process failed, due to the mismatch
between the relayfs and kernel(Kernel version: 2.6.18-rc3; systemtap
version : snapshot20060826). The details are attached.

I think it's better to have an INSTALL doc.

Best regards.

I released the latest STPTracer scripts including a logfile merging tool.
You can download it from this URL:

This tracer-script covers about a half of events which LKST provides.
And LKST Log Tools can treat the logfiles recorded by this script.
This version of STPTracer does not support the flight-recorder feature yet.
I think we must fix the format of the temporary per-cpu files before that.

By the way, in this version, I still use gBTI which I proposed before,
because it is good enough for simple transfer of binary data.

Best regards.
