I have just installed openmodelica on Debian Jessie using the instructions here: https://openmodelica.org/download/download-linux
Then I am trying to test modelica3d using the example here: https://www.openmodelica.org/doc/OpenMo … ica3d.html (under running modelica3d).

On first attempt the linker complained about two missing libraries: modbus and modcount. The former was easily installed via apt-get (just hoping it is the same one), but I am not able to figure out how to install modcount.  Any ideas?

Is there a simple way to install modcount and make it work? 
Is there a second install method where modelica3d works with no further ado?

TIA
