Re: l4 build problem on Intel Atom 330

Hi,

I have tried what you suggested(disable PERF Events) and now
I can successfully run l4linux on Intel Atom board.

But when I am compiling l4linux with Intel Graphics Card enabled
I am getting this error:

GEN     /home/mayuresh/L4/build/x86-201205290429-l4linux/Makefile

*** End of the configuration.
*** Execute 'make' to start the build or try 'make help'.
