Problems replicating the Module SDK Development example (SnowProcessor)

Hello everyone,

Following the discussion here:
https://forums.autodesk.com/t5/flexsim-forum/c-dll-not-working-when-used-inside-experimenter-works-fine/td-p/13871604

I’ve been trying to learn more about Module SDK development, so I attempted to recreate the Example Module exactly as described in the documentation:

The project compiles and builds without any issues. I followed every step, but at the end the SnowProcessor object does not appear under Fixed Resources (or anywhere else in the library).

There are no build errors or FlexSim errors — simply nothing shows up.
My module folder structure looks like this (screenshot below).

I also tried running compiling in Debug mode with the same result.

We’re using FlexSim 2025 Update 1.

Questions:

What’s the correct way to troubleshoot this?
Is there a common cause for a module that compiles successfully but fails to register its objects in the library?

Any guidance would be greatly appreciated.

Thanks in advance!

I don't know if this was different in prior versions or why it's not mentioned in the example. But for an object to be shown in the library there needs to be an entry for it in

"MAIN:/project/exec/globals/LibraryGroups". You can also copy an existing node from there and change the droppath to the new processor (the base processor uses "popoutChoices" instead of a single droppath, so I would choose a different one to copy, like the queue).
