MDT installation:

The most convenient way to install MDT is by instructing Eclipse to fetch the plugin from the
update site which is located at http://www.ida.liu.se/~pelab/modelica/OpenModelica/MDT/.
If you are not sure how to accomplish this, just follow the instructions below.

  • Start Eclipse
  • Select Help -> Software Updates -> Find and Install... from the menu
  • Select Search for new features to install and click Next
  • Select New Remote Site...
  • Enter MDT as name and http://www.ida.liu.se/labs/pelab/modelica/OpenModelica/MDT/ as URL and click OK
  • Make sure MDT is selected and click Finish
  • In the updates dialog select the MDT feature and click Next
  • Read through the license agreement, select I accept... and click Next
  • Click Finish to install MDT

    • Another way to install MDT is by downloading a zip file, unzip it locally and point the Eclipse to the unpacked directory.

  • Download the latest zip file from here
  • The zip file will unpack to a local directory called "mdt"
  • Start Eclipse, then go Help->Software Updates...
  • Add the "mdt" directory as a local site (this is different from version to version) and then install the latest version of MDT from this local site.
