The parent page of this page is Tip Cross Compiling OpenFOAM in Linux For Windows with MinGW - please visit it for more information.

1 Introduction

This is an exhaustive step by step guide on how to fully cross-compile OpenFOAM 1.7.0 in Linux for Windows, for both 32 and 64 bits architectures (from and to), using the patches available here. NOTE: for cross-compiling in Cygwin for Windows, see the section Using Cygwin for cross-compiling OpenFOAM.

These patches are a continuation of the ones for OpenFOAM 1.6.0 (see Cross Compiling OpenFOAM 1.6 in Linux For Windows with MinGW). These are now based on Symscape's "v11" patch for OpenFOAM 1.6.x available here. For a brief description on the differences between the patches on this page and the ones on Symscape's page, see the Introduction chapter page on the parent page.

With this guide and available patches, you should be able to cross-compile the whole and complete OpenFOAM libraries and applications, using MPICH2 instead of Open MPI for parallel computing. Currently you can cross-compile using mingw-w64 for both 32 and 64 bit versions. These enable you to build OpenFOAM 1.7.0 for Windows 32 and 64 bit versions, from Linux 32 and 64bit architectures. See the chapter Notes on what doesn't work and why, for information on things that don't work properly. NOTE: The old build scripts from the 1.6 version are still available on these patches, although not tested yet, and should also allow you to build with mingw32. For more information about them, see the 1.6 patch version page, chapter Building the cross-compiler.

Versions these patches apply to:

Other versions and common information to all MinGW cross-compiled versions is available in the page Tip Cross Compiling OpenFOAM in Linux For Windows with MinGW.

Support for this page is available at OpenFOAM's forum here.

2 Get OpenFOAM packages

1. In your Linux machine, open a terminal window (example) and create the folder $HOME/OpenFOAM:

   mkdir $HOME/OpenFOAM
   cd $HOME/OpenFOAM

2. Get OpenFOAM-1.7.0.gtgz and ThirdParty-1.7.0.gtgz from the OpenFOAM's sourceforge.net project page and copy/move them to the folder $HOME/OpenFOAM. If you want direct download from the terminal, then do:

   wget http://downloads.sourceforge.net/foam/OpenFOAM-1.7.0.gtgz?use_mirror=mesh
   wget http://downloads.sourceforge.net/foam/ThirdParty-1.7.0.gtgz?use_mirror=mesh

3. Extract both files, by running in a terminal:

   tar xzf OpenFOAM-1.7.0.gtgz
   tar xzf ThirdParty-1.7.0.gtgz

3 Things needed for properly cross-compiling OpenFOAM 1.7.0

STILL HAVE TO FINISH UPDATING PACKAGES NAMES

The following packages should allow you to both build OpenFOAM for Linux and Windows:

• The packages needed in Linux (these are Ubuntu 10.04 package names) are: flex git-core build-essential binutils-dev python-dev libqt4-dev libreadline5-dev wget zlib1g-dev texinfo byacc bison.
• For the x86_64 Linux platform, you will also need: gcc-multilib
• The packages required for documentation are: doxygen graphviz.
