Oh alright then, I'll ignore the error if it won't directly cause problems. Anyway I am not using Digital components.

The SystemDynamics problem remains. It still tells me

Did not know about omlib-modelica, I obtained it from the modelica website and dumped it in the user-specific modelica folder after a lot of trial-and-error.

I was able to obtain omlib-modelica-3.2.1 latest for openmodelica-1.11 (I was only able to see the x86_64 version, so that's what I installed).

I receive an error about modelica path on starting OMEdit:

I installed the nightly from the RPM repository following the instructions at https://openmodelica.org/download/download-linux .

OMEdit Version : 1.12.0~dev-305-g8329606 . Connected to OpenModelica 1.12.0~dev.alpha1.

Sorry for the delay.

Bump!! Can anyone help? I want to use it for a modelling exercise at work, but can't get it to work....

I'm a total beginner and I'm trying to learn Modelica modelling, starting with using the GUI to transition from Simulink. Hence I tried to use OpenModelica because of OMEdit. I am using Fedora 25, but it is  repeatedly giving me errors for seemingly trivial operations.

First of all, the moment I started OMEdit, it gave me errors that Modelica and ModelicaReference libraries were not found. Later I had to download it from the Modelica  website and unzip it into my .openmodelica directory. This instruction was not given anywhere, and it required a lot of searching to piece together an idea of what I needed to do.

Next, I did the same with the System Dynamics library (https://github.com/modelica-3rdparty/SystemDynamics). Then in OMEdit, I click File, mouse on System Libraries, and clicked SystemDynamics. I got the following error in the Messages Browser:
