Dear community, 

I want to call EnergyPlusToFMU from a Python script on a research computing platform based on Linux. When I run the Python script through a job script, EnergyPlusToFMU does not create FMUs, and I get the following errors:

Reading input and weather file for EnergyPlusToFMU program.

Does someone know where the errors are coming from and what I can do about them? 

Thank you, 
Esther

I see some warnings but no error? 

Could you point me to the error?

Sorry, I meant warnings and not errors.
There are only the warnings and yet no FMUs that are created.

When you run the script on your local machine, do you see the same warnings though the FMUs are created?

Hi Thierry,
not at all. On my local Windows machine, everything is fine and the FMUs are created smoothly.

Hi Thierry,

I have been in touch with the research computing support team from my uni, and they recommended to load another compiler instead of the default Intel compiler. I have run EnergyPlusToFMU with the GNU compiler (v4.9.2) now, and it seems to work! 

Little side note: Although EnergyPlusToFMU creates the FMUs, I still get the warnings, but they apparently do not mean that anything goes wrong.

Thanks for your help, 
Esther
