Instructions to build DICE

[fbob]

First of all thanks for sharing DICE source code !

I'm having issues to build DICE, I may be wrong but I found no instruction that explain how to build it.
How can I start ?

Thanks a lot and best wishes for your project :)

Thanks!

Instructions can now be found in INSTALL.md.
It is also possible to download the current release and use the included thirdparty folder before executing qmake and make. This way there is no need to build qt, python and vtk from source. (only tested on ubuntu 14.10)

This issue should stay open until we are sure that everything works out.

Hello!
Build fails because it definitly requires MPI. I tried to remove -DVTK_Group_MPI=ON from build_vtk.sh but then dice build fails with link errors. Can I build dice without MPI?

Hi @vehsakul,

It seems to be an issue with VTK compilation. I am pretty sure that removing "-DVTK_Group_MPI=ON" will not work, because camake needs this parameter. So you can just try: "-DVTK_Group_MPI=OFF".

Anyway, It would be great if you could give some information about your system. What distribution do you use? Have you already installed OpenFOAM (which already has mpi) and what exactly is the error message?

Thanks

-DVTK_Group_MPI=OFF is probably the default, so VTK compiles.
The errors are:
/usr/bin/ld: cannot find -lvtkParallelMPI-6.2
/usr/bin/ld: cannot find -lvtkFiltersParallelGeometry-6.2
/usr/bin/ld: cannot find -lvtkFiltersParallelMPI-6.2
/usr/bin/ld: cannot find -lvtkIOMPIImage-6.2
/usr/bin/ld: cannot find -lvtkIOMPIParallel-6.2
/usr/bin/ld: cannot find -lvtkIOParallelNetCDF-6.2
The system is Ubuntu 14.04

Well, I have not installed OpenFOAM since it's not explicitly mentioned, besides pyfoam.
Maybe it then worth to add it to the dependency list?
I just wanted to build dice as quickly as possible to see what it's like. The compilation even without OpenFOAM takes quite long. It doesn't seem that VTK cannot work without MPI.

It's really difficult to say because it should look for the vtk-lib-files in your dice/thirdparty folder and not in /usr/bin. Have you created the thirdparty folder? Did you try to use the one from the latest release?

OpenFOAM is not needed, but some of the applications are only working if you have OpenFOAM installed. So it's only a dependency for some applications.
