[lustre-discuss] lustre-dkms 2.12.9 O2IBPATHS failure

[Liam Forbes]

I'm attempting to install lustre-client-dkms 2.12.9 on a Rocky Linux 8.6
system with kernel 4.18.0-372.19.1.el8_6.x86_64 and Mellanox OFED
5.7.1.0.2.1.rhel8u5.x86_64. I have the mlnx-ofa_kernel-devel RPM installed,
but the lustre configure script is giving me the following error during the
`yum install`:

You seem to have an OFED installed but have not installed it's devel
package.
If you still want to build Lustre for your OFED I/B stack, you need to
install its devel headers RPM.
Instead, if you want to build Lustre for your kernel's built-in I/B stack
rather than your installed OFED stack, either remove the OFED package(s) or
use --with-o2ib=no.

Error! Bad return status for module build on kernel:
4.18.0-372.19.1.el8_6.x86_64 (x86_64)
Consult /var/lib/dkms/lustre-client/2.12.9/build/make.log for more
information.
warning: %post(lustre-client-dkms-2.12.9-1.el8.noarch) scriptlet failed,
exit status 10

I think I've tracked it down to a "$" at the end of a grep in the /
var/lib/dkms/lustre-client/2.12.9/build/configure script, line 19530.
Running the commands manually, if I drop the "$" then the O2IBPATHS
variable gets populated.

[root at n1]# O2IBPATHS=$(eval /usr/bin/ofed_info | egrep -w
'mlnx-ofed-kernel-dkms|mlnx-ofa_kernel-devel|compat-rdma-devel|kernel-ib-devel|ofa_kernel-devel'
| xargs rpm -ql | grep '\(/openib\|/ofa_kernel/default\|/ofa_kernel\)$' |
head -n1)
[root at n1]# echo $O2IBPATHS

[root at n1]# O2IBPATHS=$(eval /usr/bin/ofed_info | egrep -w
'mlnx-ofed-kernel-dkms|mlnx-ofa_kernel-devel|compat-rdma-devel|kernel-ib-devel|ofa_kernel-devel'
| xargs rpm -ql | grep '\(/openib\|/ofa_kernel/default\|/ofa_kernel\)' |

[root at n1]# echo $O2IBPATHS
/usr/src/ofa_kernel/x86_64/4.18.0-372.19.1.el8_6.x86_64

It's hard to believe that I'm the first person to run into this, but
googling I haven't found any other reports of it being an issue. Just
thought I'd check. I'm also not sure how to insert this tweak to test if it
really fixes the configure failure.
