[Lustre-discuss] building lustre-client rpms

[Alessandro Luccaroni - Diennea]

First of all thank you for the help. The "configure string" was from 
another test server, sorry about the mess.

It seems like the "configure" always detect a patched kernel.
I tested it on a patched client node rebooted into the standard redhat 
kernel, on a RHEL 5.5 and on a fresh RHEL 5.4 installation:

[root at lustreclient3 lustre-1.8.3]# ./configure 
--with-linux=/lib/modules/`uname -r`/build
[root at lustreclient3 lustre-1.8.3]# make rpms
[root at lustreclient3 lustre-1.8.3]# ls -l /usr/src/redhat/RPMS/x86_64/
total 38656

The build process doesn't request additional rpms.
