CadQuery/cq-editor Flatpak

[roipoussiere]

I'm creating a flatpak for CadQuery/cq-editor.

The goal is to publish an all-in-one app that can be easily installed (several clicks or one command line) on all Linux distributions, without using Conda (I personally always have troubles with it).

More precisely, I'm currently working 4 flatpaks:

• a flatpak for CadQuery editor, based on OCCT.
• a flatpak for CadQuery editor, based on OCE.
• a flatpak for OpenCASCADE;
• a flatpak for the Spyder IDE.

Since those 2 lasts are CadQuery dependencies, it does't require so much effort for me to publish them but will potentially be useful for some users, so it's a good deal.

I created 2 flatpaks for CQ oce and occt in order to anticipate the cq transition to occt, while working on a ready to use cq flatpak based on oce. By the way I'm interested by some explanations about this transition to occt, I noted the presence of the OCP repo and the cq ocp branch but I don't know if it's currently working or not.

Note that I created dedicated repositories with the idea of publishing them on flathub (I will add them in its Github organization), but of course the flatpak manifest could also be included in the CadQuery/cq-editor repository if you want.

Once finished, I may eventually work on a Snap app, which is an other application packaging system similar to Flatpak (this will not be so difficult is the flatpak is functional).

This issue aims to take you informed about these flatpaks developments and to make this work more visible in order to avoid other people to work on a similar task. I will close this issue when the app will be published.

I'm currently facing some issues concerning the CadQuery Flatpak development, I list them here, maybe you can help on some of them (I also have other issues that I'm investigating by myself before to create news tickets):

• testText fails #345 (makes tests fail);
• Segmentation fault (core dumped) when running test suite after building from sources tpaviot/pythonocc-core#828 (makes tests fail);
• occt 7.2 build: xlocale.h not found tpaviot/oce#728 (not blocking);
• --build-shell: file failed to open for writing flatpak/flatpak-builder#346 (blocking).

By bad, I totally forgot this PR (CadQuery/CQ-editor#76) that I created last year, I close this and copy-paste my novel on this one. 😄
