Installing HelyxOS on 32 and 64bit Linux Distributions
Greetings to all!

After several months of occasionally thinking about the topic of running HelyxOS anywhere and based on this comment:

I've brainstormed a somewhat crazy idea yesterday where it should be possible to use VTK and OpenJDK which are provided in the latest Linux Distributions and make it work with HelyxOS! And I've managed to figure how to do it!

It's all documented here: - and as of 2nd of November 2013, it's also here: - this way more people can contribute!
The old documented/tested Linux Distributions and versions are documented in the old wiki page:

For the more recent instructions, please visit the wiki at

Note: these solutions rely on the system's own Open-MPI installation, therefore it does not require the hack with the symbolic link to ""!

I'll try to do some more tests on older distributions as well and report back!

Feel free to ask questions on this topic and to report back successful installations on other Linux distributions as well!

@Mac OS X users: try following one of these solutions, by using VTK and OpenJDK from Macports or something and share the solution you've gotten!

@Windows users: I'll have news in some time from now! Right now all I can say is what we've already said on the company where I work: :D

Best regards,

List of Linux Distributions that were tested and failed:
  • Ubuntu 10.04: VTK 5.2 is too old.
  • Fedora 16: VTK 5.6 is too old.
  • openSUSE 12.1: Had an issue with the Science repository and I gave up.
  • CentOS 5.8: VTK is missing from the EPEL repository.

Bruno, This is excellent news. I am a firm believer that software like this (eg HelyxOS, Discretizer, enGrid) are an excellent ice breaker for newbies like me and others. I saw that you also had updated a Windows version of the Discretizer. Thank you very much for these contributions.

Greetings to all!

I've finished writing and testing the latest instructions for installing Helyx-OS v2.0.0 in Ubuntu:

As already mentioned in the first post, the instructions have been copy-pasted-updated to

If anyone needs instructions for Fedora, CentOS, openSUSE or any other Linux Distribution, please let me know, so that I can add the instructions for the respective distribution!
And feel free to add to and/or improve these wiki pages!

Compiling Helyx-OS on OSX

Has any of you had any success in compiling Helyx-OS on OSX so far? It would be great to have a step-by-step introduction or at least some pieces of advice.
