USE flags

  • altivec - Add support for optimizations for G4 and G5/ppc970 processors
  • awt - Useful only when building GCJ, this enables Abstract Window Toolkit (AWT) peer support on top of GTK+
  • bootstrap - !!internal use only!! DO NOT SET THIS FLAG YOURSELF!, used during original system bootstrapping [make stage2]
  • boundschecking - Add the bounds checking patch by Haj Ten Brugge, this will DISABLE the hardened PIE+SSP patches
  • build - !!internal use only!! DO NOT SET THIS FLAG YOURSELF!, used for creating build images and the first half of bootstrapping [make stage1]
  • cilk - Support the Cilk Plus language (C/C++ based languages for parallel programming)
  • cxx - Build support for C++ (bindings, extra libraries, code generation, ...)
  • d - Enable support for the D programming language
  • 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
  • elibc_FreeBSD - ELIBC setting for systems that use the FreeBSD C library
  • examples - Install examples, usually source code
  • fixed-point - Enable fixed-point arithmetic support for MIPS targets in gcc (Warning: significantly increases compile time!)
  • fortran - Add support for fortran
  • gcj - Enable building with gcj (The GNU Compiler for the Javatm Programming Language)
  • go - Build the GCC Go language frontend.
  • graphite - Add support for the framework for loop optimizations based on a polyhedral intermediate representation
  • hardened - Activate default security enhancements for toolchain (gcc, glibc, binutils)
  • java - Add support for Java
  • jit - Enable libgccjit so other applications can embed gcc for Just-In-Time compilation. This will slow down the compiler a bit as it forces all of the toolchain to be shared libs.
  • libssp - Build SSP support into a dedicated library rather than use the code in the C library (DO NOT ENABLE THIS IF YOU DON'T KNOW WHAT IT DOES)
  • lto - Build using Link Time Optimizations (LTO)
  • mpx - Enable support for Intel Memory Protection Extensions (MPX)
  • mudflap - Add support for mudflap, a pointer use checking library
  • multilib - On 64bit systems, if you want to be able to compile 32bit and 64bit binaries
  • nls - Add Native Language Support (using gettext - GNU locale utilities)
  • nocxx - Old flag -- USE=cxx from now on
  • nopie - Disable PIE support (NOT FOR GENERAL USE)
  • nossp - Disable SSP support (NOT FOR GENERAL USE)
  • nptl - Enable support for Native POSIX Threads Library, the new threading module (requires linux-2.6 or better usually)
  • objc - Build support for the Objective C code language
  • objc++ - Build support for the Objective C++ language
  • objc-gc - Build support for the Objective C code language Garbage Collector
  • openmp - Build support for the OpenMP (support parallel computing), requires >=sys-devel/gcc-4.2 built with USE="openmp"
  • pch - Enable precompiled header support for faster compilation at the expense of disk space and memory (>=sys-devel/gcc-3.4 only)
  • pgo - Build GCC using Profile Guided Optimization (PGO)
  • pie - Build programs as Position Independent Executables (a security hardening technique)
  • regression-test - Run the testsuite and install the results (requires FEATURES=test)
  • sanitize - Build support for various sanitizer functions (ASAN/TSAN/etc...)
  • source - Zip the sources and install them
  • ssp - Build packages with stack smashing protector on by default
  • static - !!do not set this during bootstrap!! Causes binaries to be statically linked instead of dynamically
  • systemtap - enable systemtap static probe points
  • 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
  • vtv - Build support for virtual table verification (a C++ hardening feature)
