[slurm-users] auth_munge.so: Incompatible Slurm plugin version (21.08.8)

[Julien Rey]

Hello Rémy,

Indeed, libdrmaa was linked against the wrong version of libslurm:

ldd /usr/local/lib/libdrmaa.so.1.0.8
     linux-vdso.so.1 =>  (0x00007ffe17b8b000)
     libslurm.so.36 => /usr/local/lib/libslurm.so.36 (0x00007f237179f000)
     libdl.so.2 => /lib64/libdl.so.2 (0x00007f237159b000)
     libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f237137f000)
     libm.so.6 => /lib64/libm.so.6 (0x00007f237107d000)
     libresolv.so.2 => /lib64/libresolv.so.2 (0x00007f2370e63000)
     libc.so.6 => /lib64/libc.so.6 (0x00007f2370a95000)
     /lib64/ld-linux-x86-64.so.2 (0x00007f2371d7d000)

I just had to recompile drmaa to make it work again.

Somehow the error message I was getting was misleading. The fix was very 
simple actually.

Thanks for your help.

Best.

J.

> Slurm daemons, binaries and libraries check the version of the plugins matches their own version at load time. The version of the plugins is bumped on every major version of Slurm (eg. 21.08) hence plugins compiled with 21.08 cannot be loaded by programs linked with libslurm from Slurm 20.11.
