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

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.
