MODELON_LICENSE_PATH not set

[mariuseb]

Hi,

Using the latest binaries on Ubuntu 22.04 ("Spawn-0.4.1-aa189fef75-Ubuntu22.04.tar.gz"), I am trying to compile an FMU as per the commands given in "Example Usage":

• spawn modelica --create-fmu Buildings.Examples.Tutorial.Boiler.System1

However, this crashes with the following error:

Compiling Model with Optimica
Parse Model
Trouble during Optimica Compiling
1 errors found:

Error:
Could not verify license
Cause: MODELON_LICENSE_PATH not set.

---

Compile C Code
Spawn encountered an error:
"Error parsing xml document located at : /home/marius/Desktop/spawn/examples/Buildings_Examples_Tutorial_Boiler_System1/modelDescription.xml"

So if I understand correctly, one needs to obtain a license for OCT from Modeleon to get this feature working currently?

Best regards,
Marius

@mwetter I've encountered this same problem too. Is it correct that one would need to purchase a Modelon license to run it? Thanks!
Best,
Jose

NREL (@kbenne) is working on a distribution of spawn that will allow using OCT with the Buildings library and no separate license.
