Versions & arches

Use flags of 2.44

• audit Enable support for Linux audit subsystem using sys-process/audit
• caps Use Linux capabilities library to control privilege
• cet Enable Intel Control-flow Enforcement Technology (needs binutils 2.29 and gcc 8)
• clang Allow building with clang (if proper environment is set). Highly experimental. Disable to auto-force gcc usage.
• compile-locales build *all* locales in src_install; this is generally meant for stage building only as it ignores /etc/locale.gen file and can be pretty slow
• custom-cflags Build with user-specified CFLAGS (unsupported)
• doc Add extra documentation (API, Javadoc, etc). It is recommended to enable per package instead of globally
• gd build memusage and memusagestat tools
• hash-sysv-compat enable sysv linker hashes in glibc for compatibility with binary software (EAC via wine/proton)
• headers-only Install only C headers instead of whole package. Mainly used by sys-devel/crossdev for toolchain bootstrap.
• +multiarch enable optimizations for multiple CPU architectures (detected at runtime)
• multilib On 64bit systems, if you want to be able to compile 32bit and 64bit binaries
• multilib-bootstrap Provide prebuilt libgcc.a and crt files if missing. Only needed for ABI switch.
• nscd Build, and enable support for, the Name Service Cache Daemon
• old-kernel Support the oldest kernel also supported by upstream glibc, otherwise the oldest in the Gentoo tree
• perl Install additional scripts written in Perl
• profile Add support for software performance analysis (will likely vary from ebuild to ebuild)
• selinux !!internal use only!! Security Enhanced Linux support, this must be set by the selinux profile or breakage will occur
• sframe enable building with sframe backtrace support
• +ssp protect stack of glibc internals
• stack-realign Realign the stack in the 32-bit build for compatibility with older binaries at some performance cost
• +static-libs Build static versions of dynamic libraries as well
• suid Make internal pt_chown helper setuid -- not needed if using Linux and have /dev/pts mounted with gid=5
• systemd Enable use of systemd-specific libraries and features like socket activation or session tracking
• systemtap Enable enhanced debugging hooks/interface via SystemTap static probe points. Note that this isn't exclusive to SystemTap, despite the name. This provides an interface which dev-debug/gdb optionally uses, see https://sourceware.org/gdb/wiki/LinkerInterface.
• test Enable dependencies and/or preparations necessary to run tests (usually controlled by FEATURES=test but can be toggled independently)
• vanilla Do not add extra patches which change default behaviour; DO NOT USE THIS ON A GLOBAL SCALE as the severity of the meaning changes drastically
• verify-sig Verify upstream signatures on distfiles
