portage

USE flags

• apidoc - Build html API documentation with sphinx-apidoc.
• build - !!internal use only!! DO NOT SET THIS FLAG YOURSELF!, used for creating build images and the first half of bootstrapping [make stage1]
• debug - Enable extra debug codepaths, like asserts and extra output. If you want to get meaningful backtraces see https://wiki.gentoo.org/wiki/Project:Quality_Assurance/Backtraces
• doc - Add extra documentation (API, Javadoc, etc). It is recommended to enable per package instead of globally
• gentoo-dev - Enable features required for Gentoo ebuild development.
• ipc - Use inter-process communication between portage and running ebuilds.
• native-extensions - Compiles native "C" extensions (speedups, instead of using python backup code). Currently includes libc-locales. This should only be temporarily disabled for some bootstrapping operations. Cross-compilation is not supported.
• python_targets_pypy3 - Build with PyPy3
• python_targets_python3_10 - Build with Python 3.10
• python_targets_python3_11 - Build with Python 3.11
• python_targets_python3_12 - Build with Python 3.12
• python_targets_python3_9 - Build with Python 3.9
• rsync-verify - Enable full-tree cryptographic verification of Gentoo repository rsync checkouts using app-portage/gemato.
• selinux - !!internal use only!! Security Enhanced Linux support, this must be set by the selinux profile or breakage will occur
• test - Enable dependencies and/or preparations necessary to run tests (usually controlled by FEATURES=test but can be toggled independently)
• xattr - Preserve extended attributes (filesystem-stored metadata) when installing files. Usually only required for hardened systems.
