I'm making OpenModelica developmnet environment to learn OpenModelica.
But I couldn't make it. Please let me know how to make it.

---------------
I checked-out and dowloaded
   - OMDev
   - OpenModelica
   - Eclipse 3.5

I saved these folders
   - C:\om\OMDev
   - C:\om\Eclipse3.5
   - C:\om\workspace\OpenModelica
and I installed the modelica plugin to Eclipse.

I set OMDev environment variable.
     OMDev = C:\om\OMDev

I installed jdk1.8 to
   - C:\Program Files (x86)\Java\jdk1.8.0_172

I executed
   - C:\om\OMDev\SETUP_OMDEV.bat
   - C:\om\OMDev\SETUP_OMDEV_Qt5.bat

I checked below batch command correctly
   - C:\om\OMDev\tools\msys\mingw32_shell.bat
   - C:\om\OMDev\tools\msys\mingw64_shell.bat

I copied OpenModelica project file and builder file.
   C:\om\workspace\OpenModelica\
       .project-sample -> .project
   C:\om\workspace\OpenModelica\.externalToolBuilders
       OMDev-MINGW-OpenModelicaBuilder.launch-sample -> OMDev-MINGW-OpenModelicaBuilder.launch

I launched Eclipse and set workspace to C:\om\workspace\.
I created "OpenModelica" project.

On Eclipse project setting,
I add jdk-path to PATH
    PATH = C:\Program Files (x86)\Java\jdk1.8.0_172\bin;.......

I changed make.exe path
   [before]${env_var:OMDEV}\tools\msys\bin\make.exe
   [after]${env_var:OMDEV}\tools\msys\usr\bin\make.exe

I rebuild OpenModelica project, but I got any errors.

[Errors]

I think my builder-setting has any wrongs.
