Thanks Bernd. Now, it compiles

I'll follow the bug and test yours

Now a couple of questions:

1) I've compiled RedHat5  2.6.18-164.11.1 kernel using config from file
config-2.6.18-164.11.1.el5_lustre.1.8.3 extracted from package
kernel-2.6.18-164.11.1.el5_lustre.1.8.3.x86_64-ext4.rpm from Oracle
server that says:
Lustre-patched kernel for ext4(MDS/MGS/OSS Only)

Is it the right one?

2) By looking at infiniband libraries in Ubuntu LTS 10.04/Debian testing
I could see that there are mainly OFED 1.4.2 except except libibverbs
and librdmacm packages which seem to be from OFED 1.5.1 (libibverbs) and
1.5 (librdmaca).
I suppose it have done this way, due to the 2.6.32 kernel (containing
OFED 1.5.1 as you can see in docs/OFED_release_notes.txt) and openmpi
1.4.1 (coming with OFED 1.5.1), but I afraid of having problems when
using Lustre 1.8.3 on it. I asked Debian maintainer Roland Dreier but he
did not answer.

Should I worry?
