[lustre-discuss] Compiling client issue lustre 2.12.9

[Jerome Verleyen]

Dear all

I need to install client package for Lustre v2.12.9 on some Almalinux 
8.9 system. As i could'nt get rpm file, i try to compile from sours rpm 
file. I follow this recomendation from lustre'wiki:
https://wiki.whamcloud.com/display/PUB/Rebuilding+the+Lustre-client+rpms+for+a+new+kernel 


I'm facing a compile issue, and could not resolve this at this moment:

In anothee email list, they recom,end to use a CFLAGS option like this: 
-D_FORTIFY_SOURCE=0. However, this option can't resolve my issue.

Hope someone could help me on this stuff?

Best regards.
