<html><head></head><body><div style="font-family:Helvetica Neue, Helvetica, Arial, sans-serif;font-size:13px;"><div>Slurm plugins won't load if you build with certain hardening settings, in your case "bind now." Check your linker flags and make sure to remove `-z now` or `-Wl,z -Wl,now`. If you want to check beforehand that this is the issue, inspect the plugin .so with readelf -d and grep for BIND_NOW. If you see BIND_NOW, you need to rebuild slurm without bind now. Architecturally the issue is that symbols common to an executable and a plugin nowadays should be located in a separate common library to avoid circular dependencies. </div><div id="yahoo_quoted_5834896677" class="yahoo_quoted">
