 # 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 MinGW+MSys
-  - NOTE THAT YOU MUST UPDATE THIS PACKAGE IF YOU CANNOT COMPILE OpenModelica any longer!
-- Make sure you place the OMDev package into `c:\OMDev\`
-  - Follow the instructions in the `c:\OMDev\INSTALL.txt` file
+  - 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
-- You could use msys or eclipse to build OMC. Follow the instructions in **Compiling OMC using MSYS** or **Compiling OMC using Eclipse**.
+  - Follow the instructions at the bottom of the page on how to get OpenModelica sources

 ## Compiling OMC using MSYS
 
-- For 32-bit OMC start `$OMDEV\tools\msys\mingw32_shell.bat` and for 64-bit OMC start `$OMDEV\tools\msys\mingw64_shell.bat`
+- To compile 32bit OMC start `$OMDEV\tools\msys\mingw32_shell.bat`
+- To compile 64bit OMC start `$OMDEV\tools\msys\mingw64_shell.bat`

 - 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 svn directory (for me named OpenModelica).
-  - Example: if you downloaded 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
-    - Go to Environment tab and change the name of the OMDEV variable from there to point to your OMDev installation `/c/path/to/your/omdev (/c/OMDev)`
 - 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.
