cannot compile any version of openvz-sources

[youvnor]

i have tryied quite every possible configuration of apic and watchdog but nothing to do.

This is the error i get:

Code: Select all

arch/x86/kernel/apic/apic.c:1792: error: implicit declaration of function 'check_nmi_watchdog'

googling around gave me no solutions

Look at the kernel source. The error is being reported in this file:

Code: Select all

arch/x86/kernel/apic/apic.c

What file in the kernel is

Code: Select all

nmi_watchdog

declared in? Is that a variable or a function name? Either way,
there should be a C header file that apic.c needs to include
to declare/define it.

What openvz kernel version are you compiling, and what config are you using?

[youvnor]

What openvz kernel version are you compiling, and what config are you using?

I want to compile linux-2.6.32-openvz-053.5 but the problem persist with linux-2.6.32-openvz-049.6 and linux-2.6.32-openvz-062.2

I tryed removing (or building everything) all possible config from acpi and removing watchdog with no success.

my last 2.6.32.53.5 .config: http://test.dmep.it/kernel_config

i looked in it, commenting or changing but i cannot solve the problem.

Are you using the config from openvz.org site?

amd64 config 042stab.53.5

[wcg]

Have you used earlier versions of openvz kernels before?

If you have an earlier version that compiles ok, look in
/usr/src/linux/arch/x86/apic/apic.c. Are the #includes the
same as they are in the openvz kernel version with
the error? If they are, then the missing #include is in
some other header (you can have #includes that include
other .h files that include other .h files, etc; the missing
one could be down the chain somewhere).

Then compare the kernel .config files between the version
that compiles ok and the one that does not. Do they match?
If not, what options are enabled in the .config file for the
kernel that compiles that are not enabled in the kernel
that fails to compile?

amd64 config 042stab.53.5

this config work

tks

i tried looking in to it but my old kernel is really old (2.6.27) and i got a little lost

[wcg]

You could try stepping forward 1 openvz kernel version at a time
from 2.6.27 and use the last one that compiles before the one that
does not compile. Then compare the apic.c #includes from the
one that compiles with the apic.c #includes from the one with
the error (and likewise for the kernel .config options).

tks

This config really better but now i got this error, any idea how to solve it?

After spending a whole afternoon here are my finding so far

The magical kernel option that is needed to be turned on can be found here: https://bugs.gentoo.org/show_bug.cgi?id=405957#c12 but still no success
kernel hacking -> Detect Hard Lookups (nested under Detect Hard and Soft Lookups)

According this thread: http://bugs.funtoo.org/browse/FL-379 older kernels are building with gcc-4.4.5.
But current gentoo shiped with gcc 4.6.3 so unmask sys-kernel/openvz-sources-2.6.32.74.10 by adding it to package.keywords

After looking inside of ebuild file i see this: K_EXTRAEWARN="This kernel is stable only when built with gcc-4.4.x and is known
to oops in random places if built with newer compilers."
