Very Computer

Hi,

I try to compile kernel 2.4.19 with sched-2.4.19-rc2-A4.
And:

gcc -D__KERNEL__ -I/home/users/cieciwa/rpm/BUILD/linux-2.4.19/include -Wall -Wstrict-prototypes -Wno-trigraphs -O2 -fno-strict-aliasing -fno-common -fomit-frame-pointer -D__powerpc__ -fsigned-char -msoft-float -pipe -ffixed-r2 -Wno-uninitialized -mmultiple -mstring   -DKBUILD_BASENAME=main -c -o init/main.o init/main.c

                 from init/main.c:15:

[...]

gcc is in version 2.95.4

Any ideas ?

Thanx.

You've got some incomplete PPC patch somewhere,  or you're trying to
compile for an IBM 40x board, which isn't supported by the kernel.org
trees yet.

Maybe, patch is from http://people.redhat.com/mingo/O(1)-scheduler/
When I replace PPC405_ERR77(x, y) to dcbt x,y [I found this in 2.5]
This part passed correctly, but I found next error in O(1) scheduler source.

[...]
mk_defs.c: In function `main':
mk_defs.c:40: structure has no member named `counter'
mk_defs.c:41: structure has no member named `processor'

When I change this:
from:
        DEFINE(COUNTER, offsetof(struct task_struct, counter));
        DEFINE(PROCESSOR, offsetof(struct task_struct, processor));
to:
        DEFINE(COUNTER, offsetof(struct task_struct, time_slice));
        DEFINE(PROCESSOR, offsetof(struct task_struct, cpu));

I hope this is correct, I found last error :

make: *** [vmlinux] Error 1

And I don't know how to solve this problem.
I don't have PPC machine in home, this error I take when I work via
internet.

Thanx.

Well, if you aren't compiling for an IBM 40x board, PPC405_ERR77 should
be defined to nothing.  And it also looks like the O(1) scheduler patch
you're trying lacks complete PPC support.  I would again suggest that
you use 2.4.18 or 2.4.19 and whichever O(1) patch applies to that, as I
think I've seen people using O(1) on PPC under 2.4.
