What OpenModelica version are you using?

Are you trying to generate an FMU?

Thanks for your kindly reply adrpo!
The OM version is OpenModelica 1.19.0~dev-597-g11b99d9
and I did try to generate a FMU by translateModelFMU()

What model from the Buildings library?

I think this is a bug so I opened a bug report about it:
https://github.com/OpenModelica/OpenMod … ssues/8640

You could you try this:

sudo cp /usr/include/omc/c/ModelicaUtilities.h /usr/include/omc/c/fmi/

and then try to build the FMU again.

It should be fixed now with https://github.com/OpenModelica/OpenMod … sues/8640.

@Youth Can you please check and verify?
