A revival of #1581

Hi! This is the friendly automated conda-forge-linting service.

I wanted to let you know that I linted all conda-recipes in your PR (recipes/mayavi) and found some lint.

Here's what I've got...

For recipes/mayavi:

• The recipe must have a build/number section.

I just wanted to let you know that I linted all conda-recipes in your PR (recipes/mayavi) and found it was in an excellent condition.

Hi @hadim. If you have time to take this over from #1581 that is fine by me. One reason aside from lack of time that I have not updated #1581, was that I forgot that VTK was not being built on all platforms due to time limits at the free CI services. For example, the VTK feedstock does not build any OS X packages (or a python 3.4 package on linux).

https://github.com/conda-forge/vtk-feedstock/blob/bb1903e93ba81a7d55aa84879033463a31e3a0c0/recipe/meta.yaml#L19

The same skip line from the VTK recipe will need to be present in the mayavi recipe.

Well I thought the issue was easier to fix than it is.

Maybe we should both keep our PRs open and wait for help or more time to fix it.

can someone restart this build seeing how conda-forge/vtk-feedstock#13 has been merged please.

Done.

I forgot to update the build number in VTK when fixing conda-forge/vtk-feedstock#13, so I'm note sure the VTK package is yet available... See conda-forge/vtk-feedstock#19

EDIT: the VTK package fixing conda-forge/vtk-feedstock#13 is now built and available.

@dfroger Should this be restarted now? As conda-forge/vtk-feedstock#19 has been merged?

@Cadair there is another error when importing vtk on circleci:

ImportError: No module named vtkRenderingOpenGLPython

I think we need to add the same yum_requirements.txt as in vtk feedstock.

We should also skip build on OSX and linux+py34, as in vtk recipe. (I don't know why OSX and linux+py34 are skipped for VTK).

And there are also errors on appveyor that may need to be fixed...

EDIT: I created PR #2215 with these proposed changes.

[dfroger]

this can be closed, as #2215 is merged. Other PR coming for windows and osx...
