How can I install the CGroup V2 Plugin for Slurm?

edit

First:

cd ~/slurm-22.05.6/src/plugins/cgroup/v2

make clean; make

 -g -O2 -fno-omit-frame-pointer -pthread -ggdb3 -Wall -g -O1 -fno-strict-aliasing -MT cgroup_v2.lo -MD -MP -MF .deps/cgroup_v2.Tpo -c -o cgroup_v2.lo cgroup_v2.c
libtool: compile:  gcc -DHAVE_CONFIG_H -I. -I../../../.. -I../../../../slurm -DSLURM_PLUGIN_DEBUG -I../../../.. -I../../../../src/common -g -O2 -fno-omit-frame-pointer -pthread -ggdb3 -Wall -g -O1 -fno-strict-aliasing -MT cgroup_v2.lo -MD -MP -MF .deps/cgroup_v2.Tpo -c cgroup_v2.c  -fPIC -DPIC -o .libs/cgroup_v2.o

You can fix it with the following steps under Ubuntu 22.04:

sudo apt-get install libdbus-1-dev

Edit the Makefile and replace the line starting with AM_CPPFLAGS by

AM_CPPFLAGS = -I$(top_srcdir)/slurm -DSLURM_PLUGIN_DEBUG -I/usr/include/dbus-1.0 -I/usr/lib/x86_64-linux-gnu/dbus-1.0/include

Make sure that these are the correct include paths of `dbus.h and dbus-arch-deps.h

Now the build should work.

Copy the shared library:

sudo cp ~/slurm-22.05.6/src/plugins/cgroup/v2/.libs/cgroup_v2.so  /usr/local/lib/slurm

Make sure that this is the directory of your slurm installation.
