Gentoo Linux - Required Packages for Yocto Build Host

The following packages are required to build a Yocto image on Gentoo Linux. Note that several third-party guides reference incorrect package atoms — the verified atoms are listed below.

emerge -av \

  dev-lang/python:3.11 \
  dev-python/pip \
  dev-util/diffstat \
  app-admin/chrpath \
  sys-apps/texinfo \

Common mistakes in third-party guides

Several widely referenced guides list incorrect Gentoo package atoms that do not exist in the Portage tree. Use the following verified atoms instead:

• app-admin/chrpath — not dev-util/chrpath or app-text/chrpath
• app-arch/cpio — not dev-util/cpio
• dev-build/cmake — not dev-util/cmake

Python version compatibility

Prefer dev-lang/python:3.11 or dev-lang/python:3.12. Python 3.13 may cause issues with Scarthgap and Nanbield releases.
