Sci-visualization/scidavis: Qt5 data visualizer and analyzer

[Nowa-Ammerlaan]

Hi,

I wrote this ebuild for scidavis (it's like Origin but FOSS), and I thought the science overlay would be the fitting place for it. It requires two new dependencies. One is a qt5 fork of an older version of qwt-5 (qwt5-qt5, packaged as qwt:5). The other is qwtplot3d which was previously maintained by the science team in ::gentoo, but was removed for not being qt5 compatible, however, thanks to some small patches form the AUR this actually works just fine with qt5. Both the qwt:5 and qwtplot3d ebuilds are heavily based on the ebuilds previously in ::gentoo, the scidavis ebuild was written from scratch.

Relevant commits to ::gentoo dropping qwtplot3d and qwt:5: gentoo/gentoo@3b7c44c and gentoo/gentoo@34cbddb

Please let me know what you think of these ebuilds

This is a large one 😺
Gonna take some time to go through this but it looks interesting ❤️

Just made some final finishing touches, added a missing einstalldocs and fixed some indentation

There quite a lot of patches here.
Can you enable tests for these packages so that we have some sanity checking?

As far as I know there aren't any upstream tests in the tarball, there are some examples, but getting them to work will likely require more patching. Scidavis itself does have tests though, and they pass, so that at least indicates that qwtplot3d is functional in scidavis.

The -qt-4.8.0 patch makes qwtplot3d work with Qt4.8 and up, including Qt5, the patch is from the AUR
The -gcc44 patch makes qwtplot3d work with newer gcc, and is both in the AUR and in the former ::gentoo ebuild
The other patches are all copied from the former ::gentoo ebuild.
The -profile patch seems to fix the version number and remove the debug flag from CONFIG.
The -gl2ps patch makes qwtplot3d build against the system version of gl2ps, instead of the one bundled in the 3rdparty directory.
The -doxygen patch presumably fixes the compilation of the docs, though I'm unsure what exactly it is doing.
The -examples patch presumably makes the examples work outside of the source tarball, similarly to what the code behind if use examples is doing in the qwt ebuild.

I'll test this on the weekend. I'm a bit busy atm.

@epsilon-0 Any news on this?

[Nowa-Ammerlaan]

I just discovered that the USE flags were not applying correctly. E.g. with USE=origin the support for origin files was not actually enabled. I fixed that now by using the usex function instead. Then I discovered a bug in the tests (because CONFIG+=test was now applying correctly) and fixed that too https://github.com/highperformancecoder/scidavis/pull/155

Apologies I've been sick and have been resting.
Will get back to this soon.

@epsilon-0 That's alright, I hope you will get better soon :)

Thank you @heroxbd and @epsilon-0 !
