xz-utils (5.4.5)

`configure' configures XZ Utils 5.4.5 to adapt to many kinds of systems.

Usage: /bb.download/source/xz-5.4.5/configure [OPTION]... [VAR=VALUE]...

To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE.  See below for descriptions of some of the useful variables.

Defaults for the options are specified in brackets.

Configuration:
  -h, --help              display this help and exit
      --help=short        display options specific to this package
      --help=recursive    display the short help of all the included packages
  -V, --version           display version information and exit
  -q, --quiet, --silent   do not print `checking ...' messages
      --cache-file=FILE   cache test results in FILE [disabled]
  -C, --config-cache      alias for `--cache-file=config.cache'
  -n, --no-create         do not create output files
      --srcdir=DIR        find the sources in DIR [configure dir or `..']

Installation directories:
  --prefix=PREFIX         install architecture-independent files in PREFIX
                          [/usr/local]
  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
                          [PREFIX]

By default, `make install' will install all the files in
`/usr/local/bin', `/usr/local/lib' etc.  You can specify
an installation prefix other than `/usr/local' using `--prefix',
for instance `--prefix=$HOME'.

For better control, use the options below.

Optional Features:
  --disable-option-checking  ignore unrecognized --enable/--with options
  --disable-FEATURE       do not include FEATURE (same as --enable-FEATURE=no)
  --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]
  --enable-debug          Enable debugging code.

                          Default=all. Available encoders: lzma1 lzma2 delta
                          x86 powerpc ia64 arm armthumb arm64 sparc

                          Default=all. Available decoders are the same as
                          available encoders.
  --enable-match-finders=LIST
                          Comma-separated list of match finders to build.
                          Default=all. At least one match finder is required
                          for encoding with the LZMA1 and LZMA2 filters.

                          sha256
  --enable-external-sha256
                          Use SHA-256 code from the operating system. See
                          INSTALL for possible subtle problems.
  --disable-microlzma     Do not build MicroLZMA encoder and decoder. It is
                          needed by specific applications only, for example,
                          erofs-utils.
  --disable-lzip-decoder  Disable decompression support for .lz (lzip) files.
  --disable-assembler     Do not use assembler optimizations even if such
                          exist for the architecture.
  --disable-clmul-crc     Do not use carryless multiplication for CRC
                          calculation even if support for it is detected.
  --enable-small          Make liblzma smaller and a little slower. This is
                          disabled by default to optimize for speed.
  --enable-threads=METHOD Supported METHODS are `yes', `no', `posix', `win95',
                          and `vista'. The default is `yes'. Using `no'
                          together with --enable-small makes liblzma thread
                          unsafe.
  --enable-assume-ram=SIZE
                          If and only if the real amount of RAM cannot be
                          determined, assume SIZE MiB. The default is 128 MiB.
                          This affects the default memory usage limit.
  --disable-xz            do not build the xz tool
  --disable-xzdec         do not build xzdec
  --disable-lzmadec       do not build lzmadec (it exists primarily for LZMA
                          Utils compatibility)
  --disable-lzmainfo      do not build lzmainfo (it exists primarily for LZMA
                          Utils compatibility)
  --disable-lzma-links    do not create symlinks for LZMA Utils compatibility
  --disable-scripts       do not install the scripts xzdiff, xzgrep, xzless,
                          xzmore, and their symlinks
  --disable-doc           do not install documentation files to docdir (man
                          pages will still be installed)
  --enable-sandbox=METHOD Sandboxing METHOD can be `auto', `no', `capsicum',
                          or `pledge'. The default is `auto' which enables
                          sandboxing if a supported sandboxing method is
                          found.
  --enable-path-for-scripts=PREFIX
                          If PREFIX isn't empty, PATH=PREFIX:$PATH will be set
                          in the beginning of the scripts (xzgrep and others).
                          The default is empty except on Solaris the default
                          is /usr/xpg4/bin.
  --enable-silent-rules   less verbose build output (undo: "make V=1")
  --disable-silent-rules  verbose build output (undo: "make V=0")
  --enable-dependency-tracking
                          do not reject slow dependency extractors
  --disable-dependency-tracking
                          speeds up one-time build
  --enable-shared[=PKGS]  build shared libraries [default=yes]
  --enable-static[=PKGS]  build static libraries [default=yes]
  --enable-fast-install[=PKGS]
                          optimize for fast installation [default=yes]
  --disable-libtool-lock  avoid locking (might break parallel builds)
  --enable-symbol-versions
                          Use symbol versioning for liblzma. Enabled by
                          default on GNU/Linux, other GNU-based systems, and
                          FreeBSD.
  --disable-nls           do not use Native Language Support
  --disable-rpath         do not hardcode runtime library paths
  --disable-largefile     omit support for large files
  --enable-unaligned-access
                          Enable if the system supports *fast* unaligned
                          memory access with 16-bit, 32-bit, and 64-bit
                          integers. By default, this is enabled only on x86,
                          x86_64, big endian PowerPC, and some ARM systems.
  --enable-unsafe-type-punning
                          This introduces strict aliasing violations and may
                          result in broken code. However, this might improve
                          performance in some cases, especially with old
                          compilers (e.g. GCC 3 and early 4.x on x86, GCC < 6
                          on ARMv6 and ARMv7).
  --enable-werror         Enable -Werror to abort compilation on all compiler
                          warnings.

                          provide on AIX, [default=aix].
  --with-gnu-ld           assume the C compiler uses GNU ld [default=no]

Some influential environment variables:
  CC          C compiler command
  CFLAGS      C compiler flags
  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
              nonstandard directory <lib dir>
  LIBS        libraries to pass to the linker, e.g. -l<library>
  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
              you have headers in a nonstandard directory <include dir>
  CCAS        assembler compiler command (defaults to CC)
  CCASFLAGS   assembler compiler flags (defaults to CFLAGS)
  CPP         C preprocessor
  LT_SYS_LIBRARY_PATH
              User-defined run-time library search path.

Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.
