OpenModelica calls using Corba + Cygwin gc++/python + Mico

OMC calling using MICO-CORBA and Cygwin g++

For an image with the actual happening see: calling-OMC-using-corba-mico-cygwin.JPG
- beware that in the image the simulate(BouncingBall) command is missing.

Start the OMC server:
- NOTE: you can do this by starting the OMC shell which runs OMC in the background
- Otherwise you can start OMC server from the command prompt:
  + start a command prompt in windows Start->Run->cmd.exe <OK>
  + go to OpenModelica131 directory: c:\OpenModelica
  + type omc +d=interactiveCorba

Compile the corbacomm.cpp file:
- take the omc-corba-mico-cygwin-python.zip
- unpack to someplace (let's say your cygwin home directory)
- start your cygwin terminal
- cd corbacomm (if you unpacked it in your cygwin /home/your_name/corbacomm)
- use this command:
adrpo@kafka ~/dev/corbacomm
$ g++ corbacomm.cpp -o corbacomm -Imico/include -Lmico/lib omc_communication.o -lmico

- now you should have the corbacomm.exe, use it like below.
- NOTE: on your computer the URI is different, unless your user name is "adrpo" :)
- in general in Cygwin you have /cygdrive/c/ that points to your windows c: drive
- use your cygwin shell and type: /cgydrive/c/D<press TAB> and you get your
  windows Documents and Settings directory. 
- now instead of "adrpo" you should have your user name, followed by 
  Local Settings/Temp/openmodelica.objid
adrpo@kafka ~/dev/corbacomm
$ corbacomm.exe file:///cygdrive/c/Documents\ and\ Settings/adrpo/Local\ Settings/Temp/openmodelica.objid "loadFileInteractive(\"c:/OpenModelica131/testmodels/BouncingBall.mo\")"
res={BouncingBall}

adrpo@kafka ~/dev/corbacomm
$ corbacomm.exe file:///cygdrive/c/Documents\ and\ Settings/adrpo/Local\ Settings/Temp/openmodelica.objid "simulate(BouncingBall)"
res=record
    resultFile = "BouncingBall_res.plt"
end record

adrpo@kafka ~/dev/corbacomm
$ corbacomm.exe file:///cygdrive/c/Documents\ and\ Settings/adrpo/Local\ Settings/Temp/openmodelica.objid "plot(h)"
res=true

Alternatively, you can edit the corbacomm.cpp and give the
string file:///cygdrive/c/Documents.... directly there.
Also you can make it so that it send commands from cpp rather 
than command line.

I did also a python script for Cygwin Python that runs corbacomm.exe
This one also checks if the server is running! Cool!


Enjoy and report bugs!
