I would remember that if researchers were not ambitious

probably today we haven't the technology we are using!

Hi I’m trying to compile a PV kernel with debug info so I can use it with utilities like crash. I do a “make menuconfig” and enable the “compile kernel with debug info” within “kernel hacking”, within the “xen-3.3.0/linux-2.6.18-xen.hg” directory. Then a make within the same directory which builds the kernel successfully.

Try make distclean then toto Xen-3.3.0 do a make prep-kernels, then u can change the .config, but don't make anything there. Go to the top die again, do a make all.

Thanks,

Neo

Next I do a make in xen-3.3.0/ directory but this fails with the following error each time I try so can someone tell me how to build a debug kernel for xen?

Regards,

Bhaskar.
