::------------------------------------------
::
:: download gcc from: http://tdm-gcc.tdragon.net/download
:: add "C:\MinGW32\bin" to path variable
:: download and install Python: http://www.python.org/
:: download and install numpy: http://www.scipy.org/Download -> Official releases are on SourceForge: https://sourceforge.net/projects/numpy/files/

:: hints: http://www.develer.com/oss/GccWinBinaries
:: see also pdf file GccWinBinaries.pdf

::build_meDriver_pyd.cmd

setup.py build --compiler=mingw32

pause

::setup.py install build --compiler=mingw32
::the "install" option will copy the created file meDriver.pyd into the folder:
::C:\Python27\Lib\site-packages and will create a *.egg_info file there too.
::the meDriver.pyd is created in the subfolder \build\lib.win32-2.7

::It sounds like GCC 4.7.0 has finally removed the deprecated -mno-cygwin option,
::but distutils has not yet caught up with it.
::Either install a slightly older version of MinGW, or edit distutils\cygwinccompiler.py
::in your Python directory to remove all instances of -mno-cygwin.

:: --> edited distutils\cygwinccompiler.py and removed the option -mno-cygwin everywhere

::------------------------------------------

::-- solution -->
:: change the following line in meDriverModule.c
::#include
:: to the new location of the include file
::#include "C:\Python27\Lib\site-packages\numpy\core\include\numpy\arrayobject.h"

::-- solution -->
::ignored warnings for now

::------------------------------------------

::wrong reference to the meIDSmain.dll:
::rename meDriver.pyd to meDriver.dll and open it in dependency walker
::instead the meDriver.pyd uses meIDSmain.dll it references the meIDSmain_NoRPC.dll
::meIDSmain_NoRPC.dll is found as text in meIDSmain.dll

::-- solution -->
::the meIDSmain.dll is found in C:\WINDOWS\system32
::rename the file, so the gcc compiler can not find it any more
::recreate meDriver.pyd
::now the meIDSmain.dll is referenced
