Please include the full package category/name in the summary when creating bug reports.

I assume you are using some forked version of the Gentoo repository. Please ensure you are using the latest ebuild from Gentoo.

Also, please provide emerge --info and attach a build log.

(Yes, this report is coming from Chromium OS.)

But the problem comes from the fact that the [[ -f ${vimfiles}/... ]] logic was not respecting SYSROOTs, nor was it handling the file-move logic that portage can normally do post-install, if you have your blockers right [1].

But it looks like you've completely given up on USE=minimal here?

I guess that solves the problem technically, but we actually do use USE=minimal, so it's probably be nice to reintroduce it. I think it would just need a blocker, like:

## vim.ebuild
RDEPEND="minimal? ( !app-editors/vim-core )"

## vim-core.ebuild
RDEPEND="!app-editors/vim-core[minimal]"

or similar.

I don't really see the point/benefit.

Is vim-core[minimal] equivalently "small" compared to vim[minimal] (modulo perhaps some docs, etc., which can be stripped via other means)? If so, then indeed there's not much point.

[Comment 6 Mike Gilbert 2022-03-08 15:55:36 UTC]

It looks like USE=minimal cuts down the installed size of app-editors/vim-core from 36.1 MiB to 15.5 MiB. Perhaps someone could look into reducing that further.

On app-editors/vim, USE=minimal reduces the size from 3.6 MiB to 1.5 MiB.
