USE flags

  • abi_mips_n32 - 64-bit (32-bit pointer) libraries
  • abi_mips_n64 - 64-bit libraries
  • abi_mips_o32 - 32-bit libraries
  • abi_ppc_32 - 32-bit (ppc) libraries
  • abi_ppc_64 - 64-bit (ppc64) libraries
  • abi_riscv_lp64 - 64-bit (rv64) soft-float libraries
  • abi_riscv_lp64d - 64-bit (rv64) double hard-float libraries
  • abi_s390_32 - 32-bit (s390) libraries
  • abi_s390_64 - 64-bit (s390x) libraries
  • abi_x86_32 - 32-bit (x86) libraries
  • abi_x86_64 - 64-bit (amd64) libraries
  • abi_x86_x32 - x32 ABI libraries
  • bzip2 - Add support for pcregrep command to search within bzip2-compressed files (via app-arch/bzip2).
  • cxx - Build support for C++ (bindings, extra libraries, code generation, ...)
  • doc - Add extra documentation (API, Javadoc, etc). It is recommended to enable per package instead of globally
  • jit - Enable just-in-time compilation for improved performance. May prevent use of some PaX memory protection features in Gentoo Hardened.
  • libedit - Use the libedit library (replacement for readline)
  • pcre16 - Build PCRE library for 16 bit characters (e.g. UTF-16).
  • pcre32 - Build PCRE library for 32 bit characters (e.g. UTF-32).
  • readline - Add support for command line editing to pcretest, through sys-libs/readline.
  • recursion-limit - Limit match recursion to 8192; if disabled, the default limit is used, which is the same as the match limit.
  • split-usr - Enable behavior to support maintaining /bin, /lib*, /sbin and /usr/sbin separately from /usr/bin and /usr/lib*
  • static-libs - Build static versions of dynamic libraries as well
  • unicode - Add support for Unicode
  • zlib - Add support for pcregrep command to search within gzip-compressed files (via sys-libs/zlib).
