USE flags

  • debug - Enable extra debug codepaths, like asserts and extra output. If you want to get meaningful backtraces see
  • doc - Add extra documentation (API, Javadoc, etc). It is recommended to enable per package instead of globally
  • nptl - Enable support for Native POSIX Threads Library, the new threading module (requires linux-2.6 or better usually)
  • perl - Add optional support/bindings for the Perl language
  • sasl - Add support for the Simple Authentication and Security Layer
  • seccomp - Enable seccomp (secure computing mode) to perform system call filtering at runtime to increase security of programs
  • selinux - !!internal use only!! Security Enhanced Linux support, this must be set by the selinux profile or breakage will occur
  • slabs-reassign - Allow manual reassignment of memory slabs at the cost of slab optimizations.
  • static - !!do not set this during bootstrap!! Causes binaries to be statically linked instead of dynamically
  • test - Enable dependencies and/or preparations necessary to run tests (usually controlled by FEATURES=test but can be toggled independently)
