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:
