[lustre-devel] Failed to build a Lustre Storage Client on OpenVZ Kernel ! Is this a bug?

[lustre-devel] Failed to build a Lustre Storage Client on OpenVZ Kernel ! Is this a bug?

[W. Zhang]

Hello,

I'm trying to build a Lustre client on OpenVZ kernel (version:
042stab120.5, based on RHEL 6.8 kernel 2.6.32-642.6.1.el6), and some bugs
occured:

(1) When build version v2_8_59_0 in git tag repo of Lustre, I encountered
the following errors:
"

"

(2) When build old version v2_8_50_0 in git tag repo of Lustre, the
following errors display:
"

...
"

Files with full error context are attached.

So, How can I fix the problem? Is this a bug which need to be fixed?

Thanks! Any suggestion is appreciated!

Best Wishes!

Dear James and All,

Zipped file "*config.log*" is attached, file in the former is too big
(beyond the limit of 150 KB).

Thanks very much and sorry for the redundancy!

Best Wishes!

I was on vacation last week so sorry for the delay. I think I know what 
the problem is. Can you try the attached patch and see if it works.
