Re: Using the systemtap configure script on Ubuntu 9.04

Frank, a little elaboration here would be helpful!  You write:

"stap needs to be natively compiled on the development host where the arm
platform's kernel etc. were built."

This step is not described in http://omappedia.org/wiki/Systemtap at least its not obvious to me what the step is to compile stap.
Can someone take the time to describe this. Otherwise I am soon going to bail on using this tool. I have oprofile already working. The install of this tool and any support for it have just been rather painful. To be honest, I don't even know if the effort is worth while. I am trying to verify the performance of my system and this tool was recommended by Steve Dickson and for all I know this tool may be a piece of junk....if the install is any indication, I am not hopeful.

Thanks.

It looks like the wrong parts of the tool were built.  staprun needs
to be cross-compiled or natively compiled for the arm platform.  stap
needs to be natively compiled on the development host where the arm
platform's kernel etc. were built.
