port to opencascade-7.5.0

[tpaviot]

opencascade 7.50 was released a few days ago, conda packages were updated at conda-forge https://anaconda.org/conda-forge/occt

pythonocc wrapper is being updated at https://github.com/tpaviot/pythonocc-core/tree/review/port-to-occt750

The azure build relies on the conda-forge occt 7.5.0 package, it requires some updates (32bit Windows package is not available, and MacOSX build needs some additional tweaks) see https://dev.azure.com/tpaviot/pythonocc-core/_build?definitionId=2&_a=summary&repositoryFilter=2&branchFilter=87%2C87%2C87

@adam-urbanczyk @rainman110 @looooo you might be interested in following this porting effort

[tpaviot]

According to the latest azure build, it seems all osx/linux/win builds complete, and all unittest pass as well

On my machine, I checked some of the pythonocc-demos, it seems also that everything is ok, I could not find any example that doesn't work with 7.5.0, but I have to check all the scripts to be sure

A pr for a migration was already created:
conda-forge/conda-forge-pinning-feedstock@73b1681

But I am not yet sure if it's good to start with the migration now. There are other migrations also ongoing and some stuff needs to be resolved (mainly smesh + vtk9)

@looooo I do not understand what you mean, I can see/download occt7.5.0 from the anaconda conda-forge channel. What do you mean with "migration" ? migration of what ?

If the mentioned PR is merged a bot creates pr's for all occt dependent recipes to update to occt 7.5.

[tpaviot]

ok I got it, thank you

[looooo]

migration has started:
conda-forge/pythonocc-core-feedstock#4

what should we do?

[tpaviot]

pythonocc-7.4.0 can not be compiled against occt750. I recently tagged 7.5.0rc1 https://github.com/tpaviot/pythonocc-core/releases/tag/7.5.0rc1, this version should be used. Could you @looooo update the conda-forge conda recipe to this version ?

[looooo]

Should we wait for a release? @tpaviot

[looooo]

@tpaviot the rc1 tag is failing for me.

[tpaviot]

@looooo thank you for this feedback, what do you mean exactly with "failing for me" ? Does it successfully compile on your machine ? Does it successfully run all the unittests ? Did you build pythonocc on your own machine or on a compilation farm (conda-forge) ?

[looooo]

this is the error I see in the PR:

CMake Error at CMakeLists.txt:141 (find_package):
  Could not find a configuration file for package "OpenCASCADE" that is
  compatible with requested version "7.5.0".

We try to build pythonocc against occt 7.5.1.

[looooo]

@tpaviot is it possible to update the master branch to work with occt7.5.1?

@looooo done, merged into master
