warnings when compiling kernel


Is it normal to get compiler warnings while compiling the kernel?

I'm running redhat8.0, and upgrading from 2.4.28 to 2.4.20-2.25
(the rawhide distribution of 2.4.20)

While compiling, I continually get the following warning:

/usr/src/linux-2.4.20-2.25/include/linux/sched.h:559:1: warning: "cpu_online" redefined
/uar/src/linux-2.4.20-2.25/include/linux/smp.h:87:1: warning: this is the location of the previous definition

I'm using the gcc that came with 8.0 (gcc 3.2).

Any thoughts?

I can't speak to those particular warnings.. but YES.. it is very normal to get warnings when compiling a kernel. Not ERRORS, but WARNINGS.
