Able to generate loop calculations but receive error upon output.

This sounds a GCC bug incompatibility issue.
Which version of GCC are you using?

Hey Olivier,

typing gcc --version, I get:

gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-44)

I would strongly suggest to use a more recent version of GCC.
That version is completely out-dated and likely the reason of the issue.

Cheers,

Olivier

Thanks Olivier,

I am looking into how to update the gcc. Do you know how to do this for Windows? I tried mingw-get update but it wasn't recognized.

I guess you means on the linux sub-system of windows?
In that case it does depend of which unix you choose?
I guess that you are redhat base and therefore will suggest
sudo yum install gcc

even if I do not have experience with yum and gcc.

That didn't work. Here is the log:

[bandit5@pete ~]$ sudo yum install gcc

We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:

    #1) Respect the privacy of others.
    #2) Think before you type.
    #3) With great power comes great responsibility.

[sudo] password for bandit5:
bandit5 is not in the sudoers file. This incident will be reported.
[bandit5@pete ~]$ sudo install gcc
[sudo] password for bandit5:
bandit5 is not in the sudoers file. This incident will be reported.

I'm on windows using command prompt to access a supercomputer, if that helps.

Hi,

Then you should just read the documentation of the supercomputer to learn how to have access to a more recent version of GCC.

Cheers,

Olivier

Hey Olivier or whomever,

I was able to make progress and output my interaction but now I cannot launch it. Below is the log with the module list provided; Is there something you see I can adjust to generate my event?
