\`configure' configures unbound 1.20.1 to adapt to many kinds of systems.

Usage: $0 [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
                          [$ac_default_prefix]
  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
                          [PREFIX]

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

For better control, use the options below.

Fine tuning of the installation directories:
  --bindir=DIR            user executables [EPREFIX/bin]
  --sbindir=DIR           system admin executables [EPREFIX/sbin]
  --libexecdir=DIR        program executables [EPREFIX/libexec]
  --sysconfdir=DIR        read-only single-machine data [PREFIX/etc]
  --sharedstatedir=DIR    modifiable architecture-independent data [PREFIX/com]
  --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
  --runstatedir=DIR       modifiable per-process data [LOCALSTATEDIR/run]
  --libdir=DIR            object code libraries [EPREFIX/lib]
  --includedir=DIR        C header files [PREFIX/include]
  --oldincludedir=DIR     C header files for non-gcc [/usr/include]
  --datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]
  --datadir=DIR           read-only architecture-independent data [DATAROOTDIR]
  --infodir=DIR           info documentation [DATAROOTDIR/info]
  --localedir=DIR         locale-dependent data [DATAROOTDIR/locale]
  --mandir=DIR            man documentation [DATAROOTDIR/man]
  --docdir=DIR            documentation root [DATAROOTDIR/doc/unbound]

                          on the kernel to provide random source ports
  --enable-linux-ip-local-port-range
                          Define this to enable use of

                          outgoing port range. This is only for the libunbound
                          on Linux and does not affect unbound resolving
                          daemon itself. This may severely limit the number of
                          available outgoing ports and thus decrease
                          randomness. Define this only when the target system
                          restricts (e.g. some of SELinux enabled
                          distributions) the use of non-ephemeral ports.

  --with-sysroot[=DIR]    Search for dependent libraries within DIR (or the

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>
  YACC        The `Yet Another Compiler Compiler' implementation to use.
              Defaults to the first program found out of: `bison -y', `byacc',
              `yacc'.
  YFLAGS      The list of arguments that will be passed by default to $YACC.
              This script will default YFLAGS to the empty string to avoid a
              default value of `-d' given by some make applications.
  LT_SYS_LIBRARY_PATH
              User-defined run-time library search path.
  PKG_CONFIG  path to pkg-config utility
  PKG_CONFIG_PATH
              directories to add to pkg-config's search path
  PKG_CONFIG_LIBDIR
              path overriding pkg-config's built-in search path
  CPP         C preprocessor
  SYSTEMD_CFLAGS
              C compiler flags for SYSTEMD, overriding pkg-config
  SYSTEMD_LIBS
              linker flags for SYSTEMD, overriding pkg-config
  SYSTEMD_DAEMON_CFLAGS
              C compiler flags for SYSTEMD_DAEMON, overriding pkg-config
  SYSTEMD_DAEMON_LIBS
              linker flags for SYSTEMD_DAEMON, overriding pkg-config
  PYTHON_VERSION
              The installed Python version to use, for example '2.3'. This
              string will be appended to the Python interpreter canonical
              name.
  PROTOBUFC_CFLAGS
              C compiler flags for PROTOBUFC, overriding pkg-config
  PROTOBUFC_LIBS
              linker flags for PROTOBUFC, overriding pkg-config

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

    # prevent static linking of such archives. So we do filename-based
    # shared library versioning with .so extension only, which is used
    # when both runtime linking and shared linking is enabled.
    # Unfortunately, runtime linking may impact performance, so we do
    # not want this to be the default eventually. Also, we use the
    # versioned .so libs for executables only if there is the -brtl
    # linker flag in LDFLAGS as well, or --with-aix-soname=svr4 only.
    # To allow for filename-based versioning support, we need to create
    # libNAME.so.V as an archive file, containing:
    # *) an Import File, referring to the versioned filename of the
    #    archive as well as the shared archive member, telling the
    #    bitwidth (32 or 64) of that shared object, and providing the
    #    list of exported symbols of that shared object, eventually
    #    decorated with the 'weak' keyword
    # *) the shared object with the F_LOADONLY flag set, to really avoid
    #    it being seen by the linker.

        # supports has POSIX threads in a separate library.  This tends not
        # to be the way of modern systems, but it's conceivable.)

        # to get POSIX threads support; the API is always present and
        # active.  We could reasonably leave PTHREAD_CFLAGS empty.  But
        # -pthread does define _REENTRANT, and while the Darwin headers
        # ignore this macro, third-party headers might not.)

        # However, older versions of Clang make a point of warning the user
        # that, in an invocation where only linking and no compilation is
        # taking place, the -pthread option has no effect ("argument unused
        # during compilation").  They expect -pthread to be passed in only
        # when source code is being compiled.
        #
        # Problem is, this is at odds with the way Automake and most other
        # C build frameworks function, which is that the same flags used in
        # compilation (CFLAGS) are also used in linking.  Many systems
        # supported by AX_PTHREAD require exactly this for POSIX threads
        # support, and in fact it is often not straightforward to specify a
        # flag that is used only in the compilation phase and not in
        # linking.  Such a scenario is extremely rare in practice.
        #
        # Even though use of the -pthread flag in linking would only print
        # a warning, this can be a nuisance for well-run software projects
