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

Tim claims it works...
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

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 :)

And if so, could they share their recipe, please?
