Yes, it's entirely possible. Just pass an ARCH=um to your make statements,
like so:
/usr/src/linux # make menuconfig ARCH=um /usr/src/linux # make ARCH=um
I think the only disadvantages ia a minor performance hit in the guest kernel
but I don't know for certain. Hope that helps!
not very lucky, I've tryed differents kernel sources with differents failures.
One seems to arrive from the linker, the other probably is a .config issue.
please can someone send me a copy of a working .config speciging uname -r, want to use it to see if is my system to have problems or something else.
