Kernel(2.6.18) compilation error in Debian Lenny

jestinjoy · 04-29-2010, 10:35 PM

When I compiled the kernel, I get the following error.

Code:

kernel/built-in.o: In function `getnstimeofday':
(.text+0xedf2): undefined reference to `__umoddi3'
kernel/built-in.o: In function `do_gettimeofday':
(.text+0xee9d): undefined reference to `__udivdi3'

make[1]: Leaving directory `/usr/src/linux-2.6-2.6.18.dfsg.1'
make: *** [debian/stamp/build/kernel] Error 2

Then I tried installing the patches by executing the following command

Code:

 gzip -cd linux-2.6_2.6.18.dfsg.1-26etch2.diff.gz  | patch

But still I get the same error. Please help

Try this for me and paste the output here:

Code:

gcc -v

I ~suspect~ your problem may be that you're attempting to compile a 2.6.18 kernel under gcc 4.3, if so you might need to modify your cflags to include -fno-tree-scev-cprop

... A few comments about the patch(es)..
gunzip linux-2.6_2.6.18.dfsg.1-26etch2.diff.gz
patch -p1 < linux-2.6_2.6.18.dfsg.1-26etch2.diff

And you will see the directory ' debian/ ' appear.
Which contains patches to be applied with: patch -p<option> < <file>
It is your decision, which to use. Examples :

debian/patches : 48 patches
debian/patches/bugfix/ : 213 patches
debian/patches/bugfix/all/ : 55 patches
debian/patches/bugfix/all/CVE-2009-0029/ : 65 patches
debian/patches/bugfix/all/vserver/ 4 patches
debian/patches/debian/ : 7 patches
debian/patches/debian/dfsg/ : 6 patches
debian/patches/features/ : 18 patches
debian/patches/features/all/ : 8 patches
debian/patches/features/all/drivers/ : 25 patches
debian/patches/features/all/xen/ : 10 patches
debian/patches/features/arm/ : 7 patches

Why are you trying to compile such an old kernel? 2.6.18 was probably what came with Etch. I think lenny was 2.6.26 or better. Maybe the headers in your source tree are not correct? Anyway, the files it references must be from the headers math.h or something like that. Are you trying to reference a deprecated function?

As I suspected, add "-fno-tree-scev-cprop" to your CFLAGS.
