compiling kernel 2.2.26 on a recent distro
 

Hi All,

I am trying to compile the latest 2.2 kernel (2.2.26) for an embedded system (386 processor class).

I am using an up-to-date gentoo with gcc 3.3.2 and kernel 2.4.26 SMP.
I have also tried compiling 2.2.25 and 2.2.23 with similar problems on a RedHat based system as well (with similar errors).


*** make output ***
divinity linux-2.2.26 # make bzImage

I am confused as to why pristine released kernel sources don't cleanly complie. I ran a make mrproper ; make menuconfig ; make dep before I performed the make bzImage. In this example, I didn't do any configuration so I know that the cpu type is set wrong.

Can anyone shed some light on what might be happening?

Thanks in Advance,
Adrian

Some of my gray cells claim that older kernels
NEED to be compiled with a 2.95.3 or, even
better, egcs compiler ...

Haven't recompiled a 2.2 kernel since late 2000, though.

Thanks for the tip.

I installed gcc 2.95.3 and got to work.

I believe my current difficulty is the linux include files (installed in /usr/include/linux). gcc 2.95.3 now complains about using them (I'm guessing 2.4 vintage) when trying to compile my 2.2 series kernel.

How would I go about overriding the include directory for the linux headers?

I have tried moving the /usr/include/linux directory to a backup location so that gcc won't look in it and then tried the following command:

make CC=/root/gcc/bin/gcc INCLUDE=/root/linux-2.2.26/include bzImage

The complier still doesn't know where to find the include files.

I've tried copying the contents of /linux-2.2.26/include/linux into the default /usr/include/linux directory (made a backup, of course) but that didn't work either. The build process complained about specific header files being in the wrong locations. I would think there would be a way to do this without having to klober my system include directory...

FYI, here is the command that make issues:
/root/gcc/bin/gcc -Wall -Wstrict-prototypes -O2 -fomit-frame-pointer -fno-strict-aliasing -pipe -fno-strength-reduce -m386 -DCPU=386 -c -o init/main.o init/main.c

Any further help would be deeply apprecieated!

TIA,
Adrian
