Kernels do not compile-- Checksum.S
Last modified: 2008-05-01 11:37:58 EDT
As an example, Checksum.S and components containing bits of ASM code seem
not to compile with EGCS/GCC 2.96 experimental. I don't know if this
problem is with my system or not (I've installed only RH7.0 components and
all that are necessary; I'm definitely using the GLIBC and the STD libs
from the RH7 package).
I have found though, that using an older, say 1.1.2, version of EGCS seems
to work to compile things like Checksum.S in the arch library of the linux
kernel, but it causes more errors in the long run.
The kernel needs to be built with 'kgcc'. The kernel right now contains stuff
that isnt clean enough
to build with the newer compiler. Edit the top kernel makefile and change the
definition of CC

Changng the CC def does not work. It just spawns the compile with a different
set of errors.
Depends on what you have done.
CC =$(CROSS_COMPILE)kgcc -D__KERNEL__ -I$(HPATH)
in the toplevel Makefile, or compile with
make CC='kgcc -D__KERNEL__ -I$(HPATH)'
or 2.2.18pre will do it for you.
Or you can apply
and gcc 2.96 should build 2.2 kernel (but if you want to be safe, do one of the
