Hi Mladen!!
I working right now with another person in a template for Void Linux.
Here is where we are:
I will copy in plain text the template for our first aproach:
# Template file for 'Sunflower'
pkgname=Sunflower
version=0.4.62
revision=1
wrksrc="Sunflower-0.4-62"
build_style=python3-module
#hostmakedepends="python3-setuptools"
makedepends="python3-setuptools"
depends="gtk+3 python3-gobject desktop-file-utils python3-chardet librsvg"
short_desc="Small and highly customizable twin-panel file manager for Linux with support for plugins"
license="GPL-3.0-or-later"
homepage="
https://github.com/MeanEYE/Sunflower"
distfiles="
https://github.com/MeanEYE/${pkgname}/archive/0.4-62.tar.gz"
checksum=76f6e16a8e2761a13cfde56c5ee3625afd7e7286942ef75d67eca65384214b14
Our first bump was the error message about gi module which is (at least that's what we found out) part of the package python3-gobject.
Our second aproach
came to a similar error, this time with the module setuptools.
I dont know if you could give us a hint, but at least its worth a try.
Thanks in advance,
José Santos
