vtk has hard links that seem to prevent anaconda libraries relocation

[doutriaux1]

using anaconda built vtk from our repo we cannot export svg any longer

import vcs
x=vcs.init()
x.plot([1,2,3,4,3,2,1])
x.svg("fail")

results in:

----> 1 x.svg("fail")

@danlipsa @sankhesh please take a look and provide any input, this is really important. Thanks.

[sankhesh]

@doutriaux1 When conda compiles VTK, does it enable the module Module_vtkIOExportOpenGL ? That is the module that provides vtkGL2PSExporter.

[doutriaux1]

@sankhesh I passed it the exact same options as we do for our build. If I build with these options it seems to work, it's a relocation issue I think. Looks like some path are hard coded.

[doutriaux1]

@sankhesh I will try to manually turn this on anyway, thanks for the pointer.

[doutriaux1]

ok I see it in the log, we'll see if it picks it up

-- Backend OpenGL modules: vtkIOExportOpenGL;vtkRenderingVolumeOpenGL;vtkRenderingContextOpenGL;vtkRenderingLIC;vtkRenderingOpenGL;vtkRenderingGL2PS

[doutriaux1]

@sankhesh that was it! You're a genius!

[doutriaux1]

@sankhesh is there an option to turn on ALL modules? Thanks

[sankhesh]

@doutriaux1 Awesome.

There is an option to enable all modules : VTK_BUILD_ALL_MODULES

However, I would suggest not to use it. That would build a whole LOT MORE code than required.

[doutriaux1]

@sankhesh I'll give it a try, since it's for anaconda we only build it once in a long while so that might be worth it.

@doutriaux1 please do not use / turn "VTK_BUILD_ALL_MODULES" it will increase the binary size unnecessarily.

[doutriaux1]

yes I noticed and it also needs mpi and all that we don't necessarily want on.
