openafs 1.4.12+dfsg-3 kernel module failed to build on2.6.32-305-ec2

[zwluxx]

On a Lucid amd64 system with kernel 2.6.32-305-ec2 (as a Xen guest in a RHEL5/CentOS5 Dom0),

compiling afs kernel module (openafs-modules-source 1.4.12+dfsg-3) failed:

...
checking if linux kbuild requires EXTRA_CFLAGS... yes
checking for linux kernel module build works... no
configure: error: in `/usr/src/modules/openafs':
configure: error: Fix problem or use --disable-kernel-module...
See `config.log' for more details.

config.log does not give any more information than that. afs kernel module builds just fine for
2.6.32-21/22 generic and server kernels.

Can you please attach a copy of config.log anyway?

Anders,

I sent a config.log file to the bug report.

Thank you.

Ah, but there _is_ more information in config.log:

I have reported this as bug 576558 in linux-ec2. You may be able to work around it by repairing the broken symlink:

sudo ln -nsf asm-x86 /usr/src/linux-headers-2.6.32-305-ec2/include/asm

Thanks, Anders!

I didn't pay that much of detail to see the problem.

asm was pointed to non-existent asm-x86_64 directory

I have now change the sym link (/usr/src/linux/include)

asm -> asm-x86_64

All is well with openafs. Thank you very much for trouble-shooting. I
should have seen this.

This bug is in 2.6.32-308-ec2 kernel as well.

[Russ Allbery (rra-debian)]

Not a bug in openafs but rather a bug in the build system for these kernels, so marking the openafs bug as invalid accordingly (since it was already reported separately as a bug against the broken package).
