Editing Gentoo Linux (section)

===Portability===
Inasmuch as Gentoo is a source-based distribution with a repository describing how to build the packages, adding instructions to build on different [[Instruction set architecture|machine architectures]] is particularly easy.<ref name="Horan2013">{{cite book|author=Brendan Horan|title=Practical Raspberry Pi|url=https://books.google.com/books?id=5Vy_UfRQduQC&pg=PA222|date=March 26, 2013|publisher=Apress|isbn=978-1-4302-4971-9|pages=222–|access-date=April 20, 2020|archive-date=March 26, 2023|archive-url=https://web.archive.org/web/20230326011821/https://books.google.com/books?id=5Vy_UfRQduQC&pg=PA222|url-status=live}}</ref>

Originally built on the [[IA-32]] architecture, Gentoo has since been ported to many others. It is officially supported and considered stable on IA-32, [[x86-64]], [[PA-RISC]], [[32-bit computing|32-bit]] and [[64-bit computing|64-bit]] [[PowerPC]], 64-bit [[SPARC]], [[DEC Alpha]], and 32- and 64-bit [[ARM architecture|ARM]] architectures.<ref>{{cite web |url=https://wiki.gentoo.org/wiki/Handbook:Main_Page#Viewing_the_Handbook |title=Handbook:Main Page - Gentoo Wiki |access-date=2018-08-31 |archive-date=March 18, 2017 |archive-url=https://web.archive.org/web/20170318083659/https://wiki.gentoo.org/wiki/Handbook:Main_Page#Viewing_the_Handbook |url-status=live}}</ref> It is also officially supported but considered in-development state on [[MIPS architecture|MIPS]],<ref>{{cite web|url=https://wiki.gentoo.org/wiki/Project:MIPS|title=Gentoo/MIPS|publisher=gentoo.org|access-date=2014-01-06|archive-date=January 6, 2014|archive-url=https://web.archive.org/web/20140106202500/https://wiki.gentoo.org/wiki/Project:MIPS|url-status=live}}</ref> [[Cell (microprocessor)|PS3 Cell Processor]], [[IBM Z|System Z/s390]].<ref>{{cite web |url=https://dev.gentoo.org/~vapier/s390/ |title=Gentoo Linux Documentation – s390 Installation Document |publisher=dev.gentoo.org |date=2004-05-12 |access-date=2010-01-28 |archive-date=July 28, 2011 |archive-url=https://web.archive.org/web/20110728051203/http://dev.gentoo.org/~vapier/s390/ |url-status=live}}</ref> Official support for 32-bit SPARC, SuperH and Itanium have been dropped.<ref>{{cite web |url=https://devmanual.gentoo.org/archs/sparc/index.html |title=Gentoo Development Guide: Arch Specific Notes – SPARC |publisher=devmanual.gentoo.org |access-date=2018-02-10 |archive-date=September 1, 2018 |archive-url=https://web.archive.org/web/20180901113131/https://devmanual.gentoo.org/archs/sparc/index.html |url-status=live}}</ref><ref>{{cite web |title=*/*: Discontinue Gentoo SuperH port |url=https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=2e51443573bdad1d4757bed11ed5c02f137b822e |access-date=July 23, 2020 |archive-date=July 23, 2020 |archive-url=https://web.archive.org/web/20200723053402/https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=2e51443573bdad1d4757bed11ed5c02f137b822e |url-status=live}}</ref>

Portability towards other operating systems, such as those derived from [[Berkeley Software Distribution]] (BSD), including [[macOS]], is under active development by the [[Gentoo/Alt]] project. The [[Gentoo/Alt#Gentoo/FreeBSD|Gentoo/FreeBSD]] project already has a working guide based on [[FreeSBIE]],<ref>{{cite web|url=https://wiki.gentoo.org/wiki/Gentoo_FreeBSD|title=Gentoo FreeBSD|publisher=gentoo.org|access-date=2014-01-06|archive-date=January 6, 2014|archive-url=https://web.archive.org/web/20140106211205/https://wiki.gentoo.org/wiki/Gentoo_FreeBSD|url-status=live}}</ref> while Gentoo/NetBSD, Gentoo/OpenBSD and Gentoo/DragonFly are being developed.<ref>{{cite web |url=http://www.gentoo.org/proj/en/gentoo-alt/bsd/index.xml |title=Gentoo Linux Projects – Gentoo/*BSD |publisher=Gentoo.org |date=2006-10-19 |access-date=2010-01-28 |url-status=dead |archive-url=https://web.archive.org/web/20100305161659/http://www.gentoo.org/proj/en/gentoo-alt/bsd/index.xml |archive-date=March 5, 2010 |df=mdy-all}}</ref> A project exists to get Portage working on [[OpenSolaris]].

It is also possible to install a Gentoo Prefix (provided by a project that maintains alternative installation methods for Gentoo) in a [[Cygwin]] environment on Windows, but this configuration is experimental.<ref>{{cite web |url=https://wiki.gentoo.org/wiki/Prefix/Cygwin |title=Gentoo Wiki - Prefix/Cygwin |access-date=February 10, 2018 |archive-date=November 12, 2019 |archive-url=https://web.archive.org/web/20191112090959/https://wiki.gentoo.org/wiki/Prefix/Cygwin |url-status=live}}</ref>
