Hi,

The stap has the following command line option

"stap -r RELEASE cross-compile to kernel RELEASE, instead of linux-2.6.12"
does this mean that we can cross compile the module for the kernel
source built for other architecture.

Hi Manjunath,

That option has been mainly used for compiling instrumentation for a kernel that is not currently running on the system. The assumption is that the architecture is the same for the host and target. What is your target architecture?

There has been some previous work to get systemtap cross compile to the arm processor. In particular ,Eugene Teo has gotten systemtap to work on Nokia n800:
