[LU-4750] lustre 2.5.1-rc fails to compile from source ( redhat sources )

• Status: Resolved
• Project: Lustre
• Affects Version/s: Lustre 2.5.1
• Type: Bug
• Priority: Blocker
• Reporter: James Beal

• Severity: 3

Description

I believe compilation from source is being effected by https://bugzilla.redhat.com/show_bug.cgi?id=613568

With a clean set of source linux-2.6.32-431.5.1.el6 with or without lustre patches applied but using the config file from 2.5.1-rc1

cp /local/lustre-2.5.1-RC/lustre-2.5.56/lustre/kernel_patches/kernel_configs/kernel-2.6.32-2.6-rhel6-x86_64.config ./.config

CC crypto/signature/ksign-publickey.o
crypto/signature/ksign-publickey.c:2:17: error: key.h: No such file or directory
crypto/signature/ksign-publickey.c: In function ‘ksign_init’:
crypto/signature/ksign-publickey.c:10: error: ‘ksign_def_public_key’ undeclared (first use in this function)
crypto/signature/ksign-publickey.c:10: error: (Each undeclared identifier is reported only once
crypto/signature/ksign-publickey.c:10: error: for each function it appears in.)

make[1]: *** [crypto/signature] Error 2

From http://scientificlinuxforum.org/index.php?showtopic=1324

"run make menuconfig.
1) Select "Enable loadable module support", then "Module signature verification (EXPERIMENTAL)". Disable it.
2) Then go back to the main menu, select "Cryptographic API" then "In-kernel signature checker (EXPERIMENTAL)" and disable that one too.
Then go back again, save your config and make your kernel. At least, it will pass this phase successfully."

Which gives this diff:

diff .config .config.orig

Could you please look into this one?

Thanks

While we are at it I also found one bug that prevented b2_5 from building. In libcfs/include/libcfs/posix/libcfs.h defines

struct shrinker {
;
};

Some versions of gcc don't like this. So I got around this problem by defining struct shrinker as

struct shrinker {
int pad;
}

build failed with the change above. it complains about module not signed

Hi James,

We were unable to reproduce your error. Could you describe all the steps that lead to the error?

Thanks

I have tried with 2.5.1 and it does not occur for me with that version...

Sorry for the confusion

[Peter Jones]

ok - thanks James!
