Hello once again to all mingw32 cross-compiling FOAMers,
I'll try to be brief: Windows version of MPICH2 fully works with mingw32 version of OpenFOAM 1.5.x! mpiexec works!!
Otherwise (valid only for the WM_PSTREAMLINK="LINKTOPSTREAM", in etc/bashrc-mingw32):
Oh, and don't forget to change mpich-1.2.5 to mpich2-1.0.8 in the previously posted setvars.bat batch file. To run with MPICH2, you must configure it properly (follow their manual, it's what I did... sort of...). Then to launch the case, from a command window launched with setcmd.bat, goto to your case folder, and run like this: mpiexec -n num_cores -genvlist HOME,PATH,USERNAME,WM_PROJECT_DIR,WM_PROJECT_INST_ DIR,WM_OPTIONS,FOAM_LIBBIN,FOA M_APPBIN,FOAM_USER_APPBIN,MPI_BUFFER_SIZE foamexecutable -parallel It should work without specifying the full path to the foam executable. Hope it works well for you too! Best Regards and happy mass-paralleling in Windows Bruno

Hi Bruno
GREAT WORK... :-D Really.. :-) I had almost given up trying to build OF-1.5 for win... I think that points 7.1 and 1.1 were crucial for success... And i need it since i will have to give away my laptop for repair one of these days... and back at home nobody knows what is a real operating system... ( the PC is wi##$%& ) I had already bought an usb HDD in order to continue using OpenFOAM in Linux... I am building ( more like trying to... :-D ) some sort of a reactingEngineDyMFoam solver to evaluate chemical kinetics in a spark Ignition engine... so I will have to use the Linux version of OF-1.5 to build my solvers, BCs and topological mesh operators... anyway, many thanks for making OpenFOAM available to W%&##$))& users... like the dumbass IT manager of CFD lab at University...!! Thanks a lot... :-) Alex |

Hi again Bruno,
Just one question , Supposing I wanted to port some of the OF-1.5-dev applications or libraries to OF-1.5-win that I built, I should first : Change point 1 of Symscape's tutorial in order to set the proper gcc compiler in $HOME/projects, so changing the build-mingw script. See the structure of the patches to understand what needs to be patched in /src directory, and patch the corresponding OF-1.5-dev/src/whatever correspondingly... Follow the rest of your setup in your detailed explanation, ... that would allow me to build OF-1.5-dev for win... is this correct...? Regards Alex |

Hello Alex,
I'm glad my "add-on" posts on cross-compiling are helpful! I've been thinking about following Symscape's blog/article idea. I've already set up the blog service on our web page, but I haven't yet had the time to post the tutorial on the blog... and fix some minor glitches I've already found. Also so I can stop clogging up this forum with progress status reports and lengthy tutorials ;) Anyway, on your note about building the latest OpenFOAM applications and/or libraries... I'll warn you that it's going to be a bit messy! By what I've seen, and I can only guess, that if you only want some of the programs, you'll probably have to build all of the new libraries, depending on the extent of updates/upgrades the project is undertaking. Anyway, by what I remember of step 1, you don't need to change anything on that step. It's the patching up part that is going to be more complicated. My advice is to try to use the same patches on the dev folder. Then try to adapt the patches that didn't work to the targeted files. This way, you'll start to get a grasp on what needs to be patched up and why. Then build each library accordingly to the src/Allwmake file, so you can check what is failing, one library at a time. Oh and I advise you to set the terminal's history to infinite, because you're going to get looong error reports... and the problems usually rise from the first errors! Other than that, I guess it's cross-compiling-business as usual. Regards, Bruno

Hi Bruno
I have found something strange... I will explain : I have my OF Linux versions in /root/OpenFOAM/... I Have the 1.4.1, the 1.4.1-dev the 1.5 and the 1.5-dev there, so I select the one I wanto to compile my app to by changing /root/.bashrc or sourcing the OF bashrc file... its ok so far. My "Win32" versions of OF , the 1.4.1, and the 1.5.x live in /home/alex/OpenFOAM, and my mingw32 compiler lives in /home/alex/projects and is in PATH. The mingw32 can sucessfully compile OF-1.4.1 for win, as well as OF-1.5.x thanks to your hints... The thing is : I have this app, foamToTecplot, that compiles OK for both OF-1.4.1 and OF-1.5 and OF-1.5-dev LINUX versions... AND will compile OK for OF-1.4.1 WIN version... ( so it is not the compiler's changes guilt ) BUT strangely enough, it will NOT compile for my recently ( and successfully ) built OF-1.5.x WIN... Shouldn't it do so...? I mean : the source code does not need to be patched ( compiles OK under OF-1.4.1 win ) and it does not have unresolved library dependecies ( compiles both in OF-1.4.1 and OF-1.5 Linux versions... ) The build logs are those: For the OF-1.4.1 "WIN" : ################################################## ############################# alex@iskandhar:~/Desktop/Utils_15/foamToTecplot$ wmake Making dependency list for source file foamToTecplot.C SOURCE=foamToTecplot.C ;

Hello Alex,
I think I've pinpointed the problem. The tell-tale is "-lOpenFOAM" and the undefined reference to "IPstream" and "OPstream". I remember you saying, and I quote: Quote:
So, foamToTecplot would have built "out of the box" if I hadn't gone and made things "over-optional" ;) As an example, here's what is inside OpenFOAM-1.5.x/applications/utilities/postProcessing/dataConversion/foamToVTK/Ma ke/options: EXE_INC = \ So, this means that there are 4 options to linking:
Alex, what's missing on foamToTecplot's is Pstream, including the -L indication on the whereabouts of that library! But following the example on foamToVTK's options, will enable your applications to be as "over-optional" as my patched version of OF 1.5.x ;) Best regards, Bruno

Hi Bruno
It worked.... :-) Now to the "hellish" endeavour ... build the -dev version for win... It is absolutely not possible to port the whole of the Unix toolchain to win is it... ? ... guess not... or else it would not be called "windows"... right... :-D ...? Regards Alex |
