Program fails to load library on compute node

Hi, sorry if this is not the right place to ask such questions, or if it’s a newbie question, but I have some problem that I don’t understand.

After compiling my code and running it in the debug-cpu partition with a simple test run, I get the following error:

/home/users/v/vagne/ias/exec/bin/./iasTissueSimulation: error while loading shared libraries: cannot open shared object file: No such file or directory

The strange thing is that I tried to run the same file directly on the login node without slurm (I know that it’s forbidden in general, but this one is just basically a “hello world” code) and then there was no error. Is there something that could explain somehow that the compute nodes can’t access a shared library but the login node can?

I checked that is indeed present and is located in /usr/lib64/

Let me know if I’m doing something wrong.

the login node has more stuff than the compute node, such as graphical tools and graphical library.

On the compute node:

[root@node001 ~]# ls -la /usr/lib64/
ls: cannot access /usr/lib64/ No such file or directory

On the cluster, you may want to use the module libglvnd which propvides

[root@master ~]# ml GCCcore/10.2.0 libglvnd/1.3.2

Thanks! Ok I see. It turns out that actually I don’t really need openGL for this project, it just got included by a third party library. I’ll try to compile things differently so that it does not require openGL at all.
