There must be something more, because I am trying it with
/*[root@node02 ~]# rpm -E "%{build_ldflags}"*//*
*//*-Wl,-z,relro -Wl,-z,now
-specs=/usr/lib/rpm/redhat/redhat-hardened-ld -Wl,-z,-lazy*/
It builds (as expected) but slurmd will not start due to the same error.
(Note, I have also tried LDFLAGS without --specs and without -Wl,-z-now
with the same result)
/*[root@node02 ~]# slurmd*//*
*//*slurmd: error: plugin_load_from_file:
dlopen(/usr/lib64/slurm/select_cons_tres.so):
/usr/lib64/slurm/select_cons_tres.so: undefined symbol:
powercap_get_cluster_current_cap*//*
*//*slurmd: error: Couldn't load specified plugin name for
select/cons_tres: Dlopen of plugin file failed*//*
*//*slurmd: fatal: Can't find plugin for select/cons_tres*//*
*/
So I still stand by my initial assessment of slurmd not running when
built under CentOS8, even with lazy
I see others have had the same issue and even add to comments in the
bugs, but no responses/resolution for this have been posted.
FWIW, I also see the issue with the latest slurm 20.05 pre1 code.

Hi again,
I answered this question on Oct 28. Simply use lazy binding as
required by slurm. See a copy below of my Oct 28 response to your
original thread.Just adjust the %build section of the rpm spec to
ensure that -Wl,-z,-lazy appears at the end of LDFLAGS. Problem
solved.
Isn't this something that should end up in the upstream .spec, with a if/else
condition for EL8?
At the moment we are able to use a only slightly modified version of the
original spec to build our EL7 version.

Hi Phillip,
Thanks for taking the time to reply to me - while I did search
the list before posting, I did not find your response.
Many thanks for pointing out the solution - originally, and again for
me specifically. You, and people like you keep open-source software
moving forward.
Thanks again for your time, I do appreciate it.
Kind regards,
Shane Kelly

You probably built slurm with immediate binding instead of lazy
binding. Check the tags in the plugin for BIND_NOW: $ readelf
-d /usr/lib64/slurm/select_cons_tres.so | grep BIND_NOW If you find
that tag, relink slurm with lazy binding instead, i.e. do not use
any form of "now" linking, e.g. -Wl,-z,now.> Note that the linker
will honor the last directive seen on the command line, so simply
appending -Wl,-z,lazy to the end> should suffice.

I have compiled it, but when you try to run slurmd, it throws some
errors and will not start. From a previous thread:
While I can successfully build/run slurmctld, slurmd is failing
because ALL of the SelectType libraries are missing symbols. Example
from select_cons_tres.so: # slurmd
slurmd: error: plugin_load_from_file:
dlopen(/usr/lib64/slurm/select_cons_tres.so):
/usr/lib64/slurm/select_cons_tres.so:
undefined symbol: powercap_get_cluster_current_cap slurmd: error:
Couldn't load specified plugin name for select/cons_tres: Dlopen of
plugin file failed slurmd: fatal: Can't find plugin for
select/cons_tres
# nm -D /usr/lib64/slurm/libslurmfull.so|grep powercap_
000000000010f7b8 T slurm_free_powercap_info_msg
0000000000060060 T slurm_print_powercap_info_msg
I am in the process of getting my client to purchase support so I can
have a ticket that gets attention :)

Hi,
Is there anybody who has actually managed to compile from rpm
on Centos 8?
And if so, could they share their recipe, please?
Thanks in anticipation :-)
