How to use openmodelica compiler in CLI?

I am trying to use OpenModelica compiler(omc) in the CLI, so I use the Terminalprovided in OMEdit. I tried to debug Modelica.Blocks.Examples.PID_Controller, but it seems omc couldn't find this model.

en

So I duplicated the PID_Controller model and put into a folder, then switched working directory in the CLI. At this time, omc could access the model, but it couldn't find the base model of Modelica.Icon.Example, I am guessing that omc doesn't have access to the Modelica Standard Library(MSL) loaded in the OMEdit.

My question is how to let omc load the MSL correctly.

-d are debug flags used in general by the developers

If you want to use omc from command line the easiest is to use .mos scripts:

The script: c:\writable\directory\script.mos

loadModel(Modelica); getErrorString(); // load the Modelica Standard Library (MSL)
simulate(Modelica.Blocks.Examples.PID_Controller); getErrorString(); // simulate a model
plotAll(); getErroString(); // plot all variables

Then from the command line, go to a directory where you can generate some output:

cd c:\writable\directory\
omc script.mos

See all the available API (the commands you can put in a mos script) here: https://build.openmodelica.org/Documentation/OpenModelica.Scripting.html
