Slurm Can't find plugin for select/linear

I have been following this guide to install Slurm on my node. I tried merely copying the slurmd example to slurm.conf and running sudo start slurmd, as per the guide, that generated this error output in journalctl:

Dec 29 19:16:22 Node_2 slurmd[27681]: error: plugin_load_from_file: dlopen(/usr/lib/slurm/select_linear.so): /usr/lib/slurm/select_linear.so: undefined symbol: slurm_job_preempt_mode
Dec 29 19:16:22 Node_2 slurmd[27681]: error: Couldn't load specified plugin name for select/linear: Dlopen of plugin file failed
Dec 29 19:16:22 Node_2 systemd[1]: slurmd.service: Control process exited, code=exited status=1

Dec 29 19:16:22 Node_2 systemd[1]: Failed to start Slurm node daemon.

However, I do have this plugin, I can see it:

sudo ls /usr/lib/slurm/select_linear.so
/usr/lib/slurm/select_linear.so

I also tried, sudo slurmd -cDvvvvv and got the following output.

slurmd: error: plugin_load_from_file: dlopen(/usr/lib/slurm/select_linear.so): /usr/lib/slurm/select_linear.so: undefined symbol: slurm_job_preempt_mode
slurmd: error: Couldn't load specified plugin name for select/linear: Dlopen of plugin file failed
slurmd: fatal: Can't find plugin for select/linear

I also tried sudo slurmctld -cDvvvvv and got this:

Any idea what I need to do for it to see this plugin?

Re: Slurm Can't find plugin for select/linear

I also encountered this issue. I found that modifying the CFLAGS in the PKGBUILD  as

export CFLAGS="${CFLAGS//-fno-plt/}"

fix the problem.
Note that the original CFLAGS set in /etc/makepkg.conf is "-march=x86-64 -mtune=generic -O2 -pipe -fstack-protector-strong -fno-plt".

But I am not sure why slurmd cannot find that symbol when compiled with the `-fno-plt` flag.
