build kernel when hack on it

[wsw1wsw2]

Hi,

Every time I add some printf()s to the kernel source and build it. The building system(cd /usr/src && make buildkern KERNCONF=...) will build the whole kernel.(clean all the objects in /usr/obj and rebuild all the objects)

Is there a way to build only file(s) what I've edited just like Linux's Kbuild does?

Thanks!

NO_CLEAN=1 and many more options ....

-DNO_KERNELCLEAN
check /usr/src/Makefile.inc1 for more defines.
