Arch Linux User Repository

Users who might still have the AUR/liggghts package should install the up-to-date liggghts-git instead.

Upstream hasn't published a tagged release since 2017, but the Git master branch continues to get regular updates.

I have submitted an AUR merge request from liggghts to liggghts-git, so the former will be deleted and only the latter will remain.

Ok, thanks. I changed this package to use standalone VTK as well. Since there is nowadays a working VTK package in Arch, the ugly hack with paraview is no longer needed.

Yep, after removing vtk it works fine. Unfortunately opencascade requires it which is required by elmerfem, kicad, freecad etc.

I've found this fork which lets me compile with standalone vtk so I can get by with that, thank-you for your help

Thank you for your reply. Do you have the VTK package installed? This could cause a conflict, because this liggghts package uses the VTK bundled with paraview. In the past I had several issues with the standalone VTK libraries, that is why I chose to use the VTK from paraview. I have seen that VTK is now in extra so I might reconsider and use this instead. Do you require the standalone VTK?

I also changed the build procedure in the PKGBUILD, so may I ask you to try again?

Thank-you for taking a look, I'm getting much further along now however I'm now getting a linker error:

Hi,

thanks for pointing this out. The patch 0002 is not needed anymore since this is meanwhile fixed upstream. The second error is a missing vtklib. I also had to add a wrapper script to load the VTK libraries for the executable :/. Please try the updated package and let me know if it works for you now.

Cheers, Benjamin

I can get it to start compiling by checking out tags=3.8.0 however I get compilation errors further down the line with that version
