Compiling OMC using OMDev package

  • Checkout the OMDev package from SVN https://openmodelica.org/svn/OpenModelicaExternal/trunk/tools/windows/OMDev
    • this package contains all prerequisites to compile OMC on Windows using msys2+mingw32+mingw64
    • if you get issues with OpenModelica compilation maybe you should update OMDev
  • Make sure you place the OMDev package into C:\OMDev\
    • Follow the instructions in the C:\OMDev\INSTALL.txt file
  • You should have an OpenModelica directory you got from OpenModelica GIT repository https://github.com/OpenModelica/OpenModelica
    • Follow the instructions at the bottom of the page on how to get OpenModelica sources
  • You could use msys2+mingw32 or msys2+mingw64 or Eclipse to build OMC. Follow the instructions in Compiling OMC using MSYS or Compiling OMC using Eclipse.

Compiling OMC using MSYS

  • To compile 32bit OMC start $OMDEV\tools\msys\mingw32_shell.bat
  • To compile 64bit OMC start $OMDEV\tools\msys\mingw64_shell.bat

After starting the terminal type:

cd /path/to/OpenModelica
make -f Makefile.omdev.mingw -j8

Compiling OMC using Eclipse

  • Inside the OpenModelica directory you will find a .project-sample file which you should rename to .project and do whatever modifications you need on it to reflect your paths. Windows doesn't let you create files that start with dot (.) so you do like this,
    • Start->Run->cmd.exe
    • $ cd \path\to\OpenModelica
    • $ ren ".project-sample" ".project"
  • rename the file OpenModelica/.externalToolBuilders/OMDev-MINGW-OpenModelicaBuilder32bit.launch-sample or OpenModelica/.externalToolBuilders/OMDev-MINGW-OpenModelicaBuilder64bit.launch-sample to OpenModelica/.externalToolBuilders/OMDev-MINGW-OpenModelicaBuilder32bit.launch or OpenModelica/.externalToolBuilders/OMDev-MINGW-OpenModelicaBuilder64bit.launch and do whatever modifications are needed on it to reflect your paths.
  • Installing Modelica Development Tooling (MDT) and setting your Eclipse workspace Start Eclipse and follow instructions from https://trac.openmodelica.org/documents/MDT/install/InstallingMDT.pdf to install MDT. Eclipse will restart at the end. Start Eclipse, change workspace to your installation:
    • note here that your workspace must point one directory up the OpenModelica GIT directory (for me named OpenModelica).
    • Example: if you cloned OpenModelica in a directory like this c:\some_paths\dev\OpenModelica then your workspace must point to c:\some_paths\dev\
  • Setting your project.
    • File -> New -> (Modelica Project) or File -> New -> Project -> Modelica -> Modelica Project
    • Type the name of your OpenModelica directory installation. For me OpenModelica
    • Say Finish.
  • Editing the OMDev-MINGW-OpenModelicaBuilder
    • Project->Project Properties->Builders->OMDev-MINGW-OpenModelicaBuilder->Edit
    • NOTE: In tab Main you have to change the Working Directory from "OpenModelica" to your directory name
  • Running the OMDev-MINGW-OpenModelica builder:
    • To run the OMDev-MINGW-OpenModelicaBuilder press Ctrl+B or right-click project and say rebuild.
    • Then the OMDev-MINGW-OpenModelicaBuilder will start and compile an OpenModelica/build/omc.exe.
    • If the builder refuse to start, please check the NOTES below.

Troubleshooting Eclipse/OMDev builder

If something does not work in Eclipse, please check:

  1. Is the Modelica perspective chosen in eclipse? Set it up in the right top corner.
  2. Is OMDev installed into c:\OMDev?
    • Be sure in C:\OMDev you have directories tools, bin, include and not another OMDev directory.
    • Set a OMDEV variable to point to it. Right Click on My Computer->Properties->Advanced Tab->Environment Variables. Add variable OMDEV and set the text to C:\OMDev
    • Close and restart Eclipse to pick up the OMDEV variable.
  3. Right click on the OpenModelica project in Eclipse and say Refresh
  4. Right click on the OpenModelica project in Eclipse and say Properties
    • Go to Builders and see if you have the builder OMDev-MINGW-OpenModelicaBuilder32bit or OMDev-MINGW-OpenModelicaBuilder64bit available.
  5. Right click on the OpenModelica project and say Rebuild.

If these do not work, look into your OpenModelica/.project to see if you have any reference to: OMDev-MINGW-OpenModelicaBuilder32bit or OMDev-MINGW-OpenModelicaBuilder64bit there. If you don't, then:

  • close Eclipse
  • copy your .project-sample to .project again from DOS:
    • Start->Run->cmd
    • $ cd \path\to\OpenModelica
    • $ ren ".project-sample" ".project"
  • open Eclipse and do step 3-5 above.
