modversions problem with 2.5.48 + .49

Hi,

I cannot successfully make dep on either 2.5.48 or 2.5.49 . My steps are:

cd ~/kernel/
tar xvzf linux-2.5.49.tar.gz
cd linux-2.5.49
make mrproper
make config - (output below), choosing all default options except for processor type
make dep - which fails with following output:

Generating include/linux/version.h (updated)
Making asm->asm-i386 symlink
SPLIT include/linux/autoconf.h -> include/config/* Starting the build. KBUILD_BUILTIN=1 KBUILD_MODULES=
make[1]: Nothing to be done for `include/linux/modversions.h'.

'make config' produced the following output:

So the problem seems to be that the MODVERSIONS option isn't picked up by Kconfig but 'make dep' looks for modversions.h anyway and falls over when it doesn't find it. I've tried fiddling with the configuration options (added modversions in manually, changed the module options etc.) but never get anywhere. This wasn't a problem up to 2.5.47, but the last two kernels both behave the same way. And I've tried it on two different machines with exactly the same result. What's even more puzzling to me is that nobody else seems to be having this problem since I can't find any reference on here or anywhere else on the net. So I must be making some weirdly stupid mistake. Could somebody please tell me what it is?

Thanks a bunch,

Marc

You don't need to anymore.

Try:

cd ~/kernel/
tar -xvzf linux-2.5.49.tar.gz
cd linux-2.5.49
make config, (or make menuconfig, etc)
make bzImage
cp arch/i386/boot/bzImage /path/to/kernel/images

then configure your bootloader and reboot.

*boggle*...See, I knew I was being thick ;-). Thanks a lot John!

Might I respectfully suggest the 'make dep' step be removed from the kernel main README-file then? Or am I the only one naive enough to actually go ahead and read it ;-)?

Marc

Yes, it should be updated. Also, the instructions for patching the kernel are wrong, -p1 is now in use, not -p0.

Who actually maintains the README?

John.
