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 and mingw32 for 32bit version. 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.
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
- In your Linux machine, open a terminal window (example) and create the folder $HOME/OpenFOAM:
mkdir $HOME/OpenFOAM cd $HOME/OpenFOAM
- 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
- 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
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: w3m flex build-essential binutils-dev libreadline5-dev wget zlib1g-dev texinfo byacc bison.
- The packages required for building the code documentation are: doxygen graphviz texlive-latex-base qt4-dev-tools.
- For the x86_64 Linux platform, you might will also need: gcc-multilib
- Packages that might be useful sooner or later: git-core python-dev libqt4-dev
4 Applying patches
- Copy/move the PatchesNBatches170.tar.gz file into the $HOME/OpenFOAM folder. Then unpack it by running:
tar -xzf PatchesNBatches170.tar.gz
- A new folder is created, named pnb17. Now to apply the patches, run from the $HOME/OpenFOAM folder:
patch -p0 < pnb17/OpenFOAM-1.7.0_patch patch -p0 < pnb17/ThirdParty-1.7.0_patch
- Still have to do some chmodding, for new scripts to run properly. Run the following lines in the terminal:
chmod 744 $HOME/OpenFOAM/OpenFOAM-1.7.0/src/Allclean chmod 744 $HOME/OpenFOAM/OpenFOAM-1.7.0/applications/utilities/parallelProcessing/Allwmake chmod 744 $HOME/OpenFOAM/OpenFOAM-1.7.0/bin/tutowin chmod 744 $HOME/OpenFOAM/OpenFOAM-1.7.0/bin/foamDiff chmod 744 $HOME/OpenFOAM/OpenFOAM-1.7.0/bin/backupSourceFolder chmod 744 $HOME/OpenFOAM/OpenFOAM-1.7.0/bin/backupFullFolder chmod 744 $HOME/OpenFOAM/OpenFOAM-1.7.0/bin/chtMultiRegionFixK chmod 744 $HOME/OpenFOAM/OpenFOAM-1.7.0/bin/fixPatchExeNames chmod 744 $HOME/OpenFOAM/OpenFOAM-1.7.0/tutorials/Allwmake chmod 744 $HOME/OpenFOAM/OpenFOAM-1.7.0/multiBuilder chmod 744 $HOME/OpenFOAM/ThirdParty-1.7.0/AllwcleanRegEx chmod 744 $HOME/OpenFOAM/ThirdParty-1.7.0/AllwcleanZLib chmod 744 $HOME/OpenFOAM/ThirdParty-1.7.0/AllwmakeMinGWScotch chmod 744 $HOME/OpenFOAM/ThirdParty-1.7.0/AllwmakeRegEx chmod 744 $HOME/OpenFOAM/ThirdParty-1.7.0/AllwmakeZLib chmod 744 $HOME/OpenFOAM/ThirdParty-1.7.0/build-mingw44 chmod 744 $HOME/OpenFOAM/ThirdParty-1.7.0/build-mingw45 chmod 744 $HOME/OpenFOAM/ThirdParty-1.7.0/build-pexports chmod 744 $HOME/OpenFOAM/ThirdParty-1.7.0/fixSystemMingw chmod 744 $HOME/OpenFOAM/ThirdParty-1.7.0/genMPICH2stubs chmod 744 $HOME/OpenFOAM/ThirdParty-1.7.0/getMinGWBin chmod 744 $HOME/OpenFOAM/ThirdParty-1.7.0/makeGcc
5 Getting Windows version of MPICH2 into the ThirdParty-1.7.0 folder in Linux
With these patches there is only one way to compile OpenFOAM with MPICH2, and it's done automatically by the script Allwmake.
So this chapter is only relevant in case you want to update the headers and definition files from 1.2.1p1 to another MPICH2 version:
- Download and install in Windows the MPICH2, any other version than 1.2.1p1 from here. Install both 32 and 64bit versions, if you wish to build OpenFOAM for both architectures.
- You will also have to download the source code package from that page.
- Create the folder $HOME/OpenFOAM/ThirdParty-1.7.0/mpich2-version/source/arch/include in your Linux set up (example and depending on the architectures you may want):
mkdir -p $HOME/OpenFOAM/ThirdParty-1.7.0/mpich2-1.2.1p1/source/i686/include mkdir -p $HOME/OpenFOAM/ThirdParty-1.7.0/mpich2-1.2.1p1/source/x86_64/include
- From the installed MPICH2 in Windows, you will need to copy the following files from the include folder: mpi.h mpio.h mpicxx.h. And copy those files to the folder $HOME/OpenFOAM/ThirdParty-1.7.0/mpich2-version/source/arch/include.
- Then copy the files mpi.def mpich2.def from the source code package into the folder $HOME/OpenFOAM/ThirdParty-1.7.0/mpich2-version/source.
- Now to use a version of MPICH2 other than 1.2.1p1, then edit the file $HOME/OpenFOAM/OpenFOAM-1.7.1/etc/settings.sh and find the line that has mpi_version=mpich2-1.2.1p1 and change to the version you want, as shown here.
The Allwmake script at the folder ThirdParty-1.7.0 will take care of the rest.
6 Tweaking environment options
- Choose which version you want to use:
- Custom builds:
- mingw32: for getting a 32bit version of OpenFOAM, using gcc + mingw;
- mingw-w32: for getting a 32bit version of OpenFOAM, using gcc + mingw-w64;
- mingw-w64: for getting a 64bit version of OpenFOAM, using gcc + mingw-w64;
- Using Ubuntu's 10.04 builds of mingw-w64: (Wyldckat 17:26, 2 August 2010 (UTC) - unknown at this time if other distributions use the same nomenclature)
- i586-mingw32msvc: for getting a 32bit version of OpenFOAM, using system's gcc + mingw-w64;
- amd64-mingw32msvc: for getting a 64bit version of OpenFOAM, using system's gcc + mingw-w64;
- Using builds available at mingw-w64's sourceforge.net project page [1]:
- i686-w64-mingw32: for getting a 32bit version of OpenFOAM, using the latest pre-built gcc + mingw-w64;
- x86_64-w64-mingw32: for getting a 64bit version of OpenFOAM, using the latest pre-built gcc + mingw-w64;
Variants of the "bashrc" file that is inside the folder $HOME/OpenFOAM/OpenFOAM-1.7.0/etc, have been created, to meet the most likely options. These are:- sample - <bashrc-version>
- configured for <compiler>, <mingw version>, <MPI option>, <WM_COMPILE_OPTION>, <WM_ARCH_OPTION>
- bashrc-mingw32
- configured for custom gcc, mingw32, MPI with MPICH2, Opt, DP, 32
- bashrc-mingw-w32
- configured for custom gcc, mingw-w32, MPI with MPICH2, Opt, DP, 32
- bashrc-mingw-w32-prof
- configured for custom gcc, mingw-w32, No MPI, Prof, DP, 32 (untested)
- bashrc-mingw-w32S
- configured for custom gcc, mingw-w32, MPI with MPICH2, Opt, SP, 32
- bashrc-mingw-w64
- configured for custom gcc, mingw-w64, MPI with MPICH2, Opt, DP, 64
- bashrc-mingw-w64-prof
- configured for custom gcc, mingw-w64, No MPI, Prof, DP, 64 (untested)
- bashrc-i586-mingw32msvc
- configured for system's gcc, mingw-w32, MPI with MPICH2, Opt, DP, 32
- bashrc-i586-mingw32msvcS
- configured for system's gcc, mingw-w32, MPI with MPICH2, Opt, SP, 32
- bashrc-amd64-mingw32msvc
- configured for system's gcc, mingw-w64, MPI with MPICH2, Opt, DP, 64
- NOTE: for this last one above, you will possibly need to install the mingw-w64 version for Ubuntu 10.04 available by Pali here (currently a dead link), because Ubuntu's initial version doesn't have the compiler amd64-mingw32msvc-g++.
- bashrc-i686-w64-mingw32
- configured for gcc-4.5.1 (or more recent), mingw-w32, MPI with MPICH2, Opt, DP, 32
- bashrc-i686-w64-mingw32S
- configured for gcc-4.5.1 (or more recent), mingw-w32, MPI with MPICH2, Opt, SP, 32
- bashrc-x86_64-w64-mingw32
- configured for gcc-4.5.1 (or more recent), mingw-w64, MPI with MPICH2, Opt, DP, 64
- After choosing the version you wish to build, edit the file $HOME/.bashrc and add to the end of it, a line analogous to the following line:
. $HOME/OpenFOAM/OpenFOAM-1.7.0/etc/bashrc-mingw-w32
WARNING: sometimes the leading dot doesn't work, so use the following instead:
source $HOME/OpenFOAM/OpenFOAM-1.7.0/etc/bashrc-mingw-w32
Optional: in case you want to have access to all versions without having to edit again the file $HOME/.bashrc, then instead of adding that line above, add one or more of these:
alias of170-mingw32='. $HOME/OpenFOAM/OpenFOAM-1.7.0/etc/bashrc-mingw32' alias of170-mingw-w32S='. $HOME/OpenFOAM/OpenFOAM-1.7.0/etc/bashrc-mingw-w32S' alias of170-mingw-w32D='. $HOME/OpenFOAM/OpenFOAM-1.7.0/etc/bashrc-mingw-w32' alias of170-mingw-w64='. $HOME/OpenFOAM/OpenFOAM-1.7.0/etc/bashrc-mingw-w64' alias of170-i586Dsys='. $HOME/OpenFOAM/OpenFOAM-1.7.0/etc/bashrc-i586-mingw32msvc' alias of170-i586Ssys='. $HOME/OpenFOAM/OpenFOAM-1.7.0/etc/bashrc-i586-mingw32msvcS' alias of170-x64sys='. $HOME/OpenFOAM/OpenFOAM-1.7.0/etc/amd64-mingw32msvc' alias of170-i686Dmingw='. $HOME/OpenFOAM/OpenFOAM-1.7.0/etc/bashrc-i686-w64-mingw32' alias of170-i686Smingw='. $HOME/OpenFOAM/OpenFOAM-1.7.0/etc/bashrc-i686-w64-mingw32S' alias of170-x64mingw='. $HOME/OpenFOAM/OpenFOAM-1.7.0/etc/bashrc-x86_64-w64-mingw32' alias of170-linux='export WM_ARCH_OPTION=32; . $HOME/OpenFOAM/OpenFOAM-1.7.0/etc/bashrc' alias of170-linux64='. $HOME/OpenFOAM/OpenFOAM-1.7.0/etc/bashrc'
Now, whenever you start a new terminal, run one of the alias commands; for example:of170-i686Dmingw
NOTE: Feel free to change the alias names to something more short and to your liking!
7 Build the cross compiler
In this version of patches for OpenFOAM 1.7.0, there are three types of MinGW cross-compilers, as already mentioned in the previous section Tweaking environment options. For all of these possibilities, start a new terminal. In case you chose to use the alias method, activate the OpenFOAM environment by running the respective alias command, as demonstrated before.
7.1 Using custom built MinGW cross-compilers
Valid for WM_COMPILER: mingw32 mingw-w32 mingw-w64
- Go to the ThirdParty-1.7.0 folder, in your new terminal:
cd $WM_THIRD_PARTY_DIR
- Now you have to build the cross-compiler. You can now choose which version of gcc you wish to build mingw(-w64) with. The two possibilities available are:
- to build with gcc 4.4.x version, run:
./build-mingw44
NOTE: 64bit builds of OpenFOAM provided by the resulting gcc-4.4.x+mingw-w64 will probably only run in Windows XP x64. - to build with gcc 4.5.x version, run:
./build-mingw45
NOTE: 64bit builds of OpenFOAM provided by the resulting gcc-4.5.x+mingw-w64 should run on any Windows x64, but its stability isn't 100% guaranteed.
NOTE: updates are bound to be done to the packages that these scripts use. Therefore, you should edit the script you have chosen, and check accordingly:- Near the beginning of the scripts, you will find these:
#GNU GCC and company GCCVERSION="gcc-4.5.0" GMPVERSION="gmp-4.3.2" MPFRVERSION="mpfr-2.4.2" MPCVERSION="mpc-0.8.2" #'''build-mingw45''' only BINUTILSVERSION="binutils-2.20.1" #MinGW versions MINGW32RTVERSION="mingwrt-3.18" W32APIVERSION="w32api-3.14"
NOTE: Mingw-w64 isn't version-ed because these scripts will always retrieve the latest stable 1.0 version directly from SVN.
Check if they those versions still exist or if newer ones exist, by browsing the links provided a few lines below the version variables:
GNU_URL="ftp://ftp.mirrorservice.org/sites/sourceware.org/pub/gcc/releases/${GCCVERSION}/${GCC_TARFILE}" GMP_URL="ftp://ftp.gnu.org/gnu/gmp/${GMP_TARFILE}" MPFR_URL="ftp://ftp.gnu.org/gnu/mpfr/${MPFR_TARFILE}" MPC_URL="http://www.multiprecision.org/mpc/download/${MPC_TARFILE}" BINUTILS_URL="ftp://ftp.mirrorservice.org/sites/sourceware.org/pub/binutils/releases/${BINUTILS_TARFILE}" MINGW64_URL="http://mingw-w64.svn.sourceforge.net/viewvc/mingw-w64/branches/releases/v1.0/?view=tar" #changes here only required if new stable version is launched #MinGW versions MINGW32RT_URL="http://downloads.sourceforge.net/project/mingw/MinGW/BaseSystem/RuntimeLibrary/MinGW-RT/${MINGW32RTVERSION}/${MINGW32RT_TARFILE}?use_mirror=mesh" W32API_URL="http://downloads.sourceforge.net/project/mingw/MinGW/BaseSystem/RuntimeLibrary/Win32-API/${W32APIVERSION}/${W32API_TARFILE}?use_mirror=mesh"
The respective addresses for checking available versions:
NOTE: You can also change the URLs, in case you can find a closer server to you!
- to build with gcc 4.4.x version, run:
- If no error messages appear while running the script, then you should now be ready to go to the next chapter.
7.2 Using system build of MinGW cross-compilers
Valid for WM_COMPILER: i586-mingw32msvc amd64-mingw32msvc
7.3 Using mingw-w64 automatic builds of MinGW cross-compilers
Valid for WM_COMPILER: i686-w64-mingw32 x86_64-w64-mingw32
You simply have to run the script getMinGWBin available in the folder ThirdParty-1.7.0:
cd $WM_THIRD_PARTY_DIR ./getMinGWBin
This script will search for the latest available pre-built version of the mingw-w64 compiler defined by the bashrc-compiler script for you Linux machine, whether it's i?86 or x86_64! It should also work in Cygwin.
NOTE: this script needs the application w3m, a text based browser, to be installed.
8 Cross-Compile OpenFOAM in Linux for Windows
- Open a new terminal window or tab, so it will reset environment variables and add the newly built cross-compiling gcc into the executable path variable (see Tweaking environment options). Go to the project folder as so:
cd $WM_PROJECT_DIR
- Go to the folder "OpenFOAM-1.6" and run "Allwmake":
./Allwmake
This will build the entire OpenFOAM package. This does not include: Paraview, OpenMPI and code documentation. - Optional - If you want to build the code documentation, after OpenFOAM is built, run:
wmake all doc
This is only needs to be built once, since it's the same for all architectures.
In the chapter Creating a compact help file for the code documentation is explained how to finish this step.
- Optional - If you want to be able to run the tutorial cases that need custom applications to be built, run:
wmake all tutorials
The applications will be cross-compiled and put in the folder $HOME/OpenFOAM/$USER-1.7.0/application/bin/$WM_OPTIONS, or $FOAM_USER_APPBIN for short.
- Building the mesh conversion utility ccm26ToFoam is now done automatically, when compared with the previous patch versions.
- For testing MPICH2, as described in this page's parent page, chapter Using MPICH2 with OpenFOAM in Windows, the parallel test application will be built automatically. The built executable will be placed in the folder $HOME/OpenFOAM/$USER-1.7.0/application/bin/$WM_OPTIONS, or $FOAM_USER_APPBIN for short.
