Description Arfrever Frehtes Taifersar Arahesis 2019-09-20 01:49:15 UTC
app-office/lyx-2.3.* supposedly would mostly work with Python 3.

Some recently fixed problem: (master branch) (2.3.x branch)

lyx-2.3.3.ebuild patch (see caveats in description)

We can easily support Python 3.5, 3.6, 3.7 and 3.8 starting with version 2.3.4, which is further backed by the README[0] and one remark[1] by one of the developers.

The bug 11642 for version 2.3.3 only applied to macOS from what I could tell, but the important matter was b9cc642, which was applied _after_ the release of 2.3.3 and does not justify a general move to python3 for 2.3.3.

The bug fixed in b9cc642 is only triggered when there's no ~/.lyx directory present, so given I have it I added python3_{5,6,7,8} (as specified by upstream in the README), removed the patch applied to the ebuild in files/ and the PATCHES-variable and it worked just fine (tested with 3.5, 3.6, 3.7, 3.8 both exclusively as target and single-target), including reconfiguration (diff attached).

The only remaining question is when Lyx 2.3.4 will be released. The milestone[2] indicates that it won't be long.

Lyx 2.3.4 has been released on 2020-01-31, see [1].

The patch from comment 1 does the trick for me: Lyx starts and looks to do just fine.
