conda-forge package

[looooo]

I would like to add netgen to the conda-forge channel. Currently there are several netgen-packages available with conda:

• https://anaconda.org/mhochsteger/netgen
• https://anaconda.org/cad/netgen
• https://anaconda.org/pythonocc/netgen

Maybe we could try to combine this packages and make one that is more official and satisfy all the needs of the dependent libraries.

It would be nice to have release tags too (xref: https://github.com/NGSolve/netgen/issues/8)

[looooo]

should netgen work on 32 bit windows? https://ci.appveyor.com/project/conda-forge/staged-recipes/build/1.0.22014/job/2tw3q4gjf6u1iy6w I disable it for now. Also finding tk seems to bedifficult for windows. So I disabled gui for windows.

@mhochsteger could you have a look at this PR https://github.com/conda-forge/staged-recipes/pull/5320. It should add builds for:

• py36 & py35
  • win 64 bit
  • linux 64 bit
  • linux 32 bit
  • osx

I have disabled the gui for window, because finding tk with cmake is a disaster. But any additionals can be added later on too.

To you have odeas why win 32bit doesn't work?

@looooo

• Win32 is not (anymore) officially supported. The problem in your case is the compiler ("Internal compiler error"). Any good reason you still need to support it?
• GUI on Windows has another problem: In order to build togl we need internal tcl/tk headers, which are not available. I also couldn't find any conda packages for togl.
• You got a merge request for small changes.

[looooo]

Some people still using freecad with win32... It's not a big issue if win32 is not supported by netgen as freecad can be build without netgen-meshing support.

conda package of netgen-6.2.0-1802 is now uploaded: conda install netgen -c conda-forge

@mhochsteger @JSchoeberl pyocct still needs https://github.com/NGSolve/netgen/pull/10 . Maybe it's possible to merge the PR in the next release.
