BUILD.MINGWw64

This will help you build OCE with MinGW w64/MSYS using the Oce-Win-Bundle sources:

1) MinGW w64
	Download MinGW w64 from http://mingw-w64.sourceforge.net/
	Choose Mingw-builds Project, online Installer. (You can try others as well, but this one works...)
	When Installing use POSIX as Threading Model and SEH as Exception Model (others might work too, but are untested)
	Add the /bin directory of your MinGW install to your system's PATH-Variable (e.g. C:\mingw-builds\x64-4.8.1-posix-seh-rev5\mingw64\bin)
	
2) MSYS
	Download MSYS from Mingw-builds Sourceforge Repository: 
	http://sourceforge.net/projects/mingwbuilds/files/external-binary-packages/
	Does not need installation, just extract into its own directory
	
3) CMake
	Install CMake >2.8

4) Open Cascade Community Edition
	Obtain a local copy of the current OCE repository 
		git clone git://github.com/tpaviot/oce.git
			
5) Oce-Win-Bundle
	To obtain the FreeImage, FreeType and gl2ps libraries clone the oce-win-bundle repository into its own directory:
		git clone https://github.com/QbProg/oce-win-bundle.git

6) Run CMake
    Point "Where is the source code:" to your local copy of OCE
    Build the binaries in a new specific build folder within OCE
    Hit Configure
    Choose "MSYS Makefiles" (NOT "MinGW Makefiles"!) with default native compilers
    When required: Point CMAKE_MAKE_PROGRAM to /bin/make.exe in your MSYS directory and configure again.
    Check OCE_USE_BUNDLE_SOURCE
    Check OCE_WITH_FREEIMAGE
    Check OCE_WITH_GL2PS
    Check OCE_VISUALISATION
    Use OPENMP as OCE_MULTITHREAD_LIBRARY
    Select your Installation directory with OCE_INSTALL_PREFIX
    Configure
    Select the directory of your oce-win-bundle clone with OCE_BUNDLE_ROOT_PATH
    Select your required build type (RELEASE,DEBUG..)
    Configure (and no entries should be red afterwards..)
    and Generate.

	
7) Run MSYS and make
	Start msys.bat in your MSYS-Directory (as an Administrator)
	cd into your build directory
	run 'make'
	
	Compilation is now running. It can take several hours, depending on your machine.
	
8) Install
	run 'make install'
	
If you want to compile as DEBUG, you might have to compile twice, once as RELEASE and once as DEBUG to obtain the required release and debug libraries.
If you do not need Visualisation, GL2PS etc. just uncheck them.
