Subject: 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)

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:

* Linux Kernel Configuration
...etc

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.

John.

*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 ;-)?

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.
