\`configure' configures The Glorious Glasgow Haskell Compilation System 8.2.2 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/ghc-8.2.2]
  --htmldir=DIR           html documentation [DOCDIR]
  --dvidir=DIR            dvi documentation [DOCDIR]
  --pdfdir=DIR            pdf documentation [DOCDIR]
  --psdir=DIR             ps documentation [DOCDIR]

System types:

Optional Features:
  --disable-option-checking  ignore unrecognized --enable/--with options
  --disable-FEATURE       do not include FEATURE (same as --enable-FEATURE=no)

                          Allow bootstrapping using a development snapshot of
                          GHC. This is not guaranteed to work.
  --enable-tarballs-autodownload
                          Automatically download Windows distribution binaries
                          if needed.

                          [default="$UnregisterisedDefault"]
  --disable-ld-override   Prevent GHC from overriding the default linker used
                          by gcc. If ld-override is enabled GHC will try to
                          tell gcc to use whichever linker is selected by the
                          LD environment variable. [default=override enabled]
  --disable-largefile     omit support for large files
  --enable-bfd-debug      Enable symbol resolution for -debug rts ('+RTS -Di')
                          via binutils' libbfd [default=no]
  --enable-large-address-space
                          Use a single large address space on 64 bit systems

  --enable-dwarf-unwind   Enable DWARF unwinding support in the runtime system
                          via elfutils' libdw [default=no]

Optional Packages:
  --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
  --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
  --with-ghc=ARG          Use ARG as the path to GHC [default=autodetect]
  --with-iconv-includes   directory containing iconv.h
  --with-iconv-libraries  directory containing iconv library

  --with-curses-includes  directory containing curses headers
  --with-curses-libraries directory containing curses libraries
  --with-gcc=ARG          Use ARG as the path to gcc (obsolete, use CC=ARG
                          instead) [default=autodetect]
  --with-clang=ARG        Use ARG as the path to gcc (obsolete, use CC=ARG

  --with-nm=ARG           Use ARG as the path to nm [default=autodetect]
  --with-objdump=ARG      Use ARG as the path to objdump [default=autodetect]
  --with-ar=ARG           Use ARG as the path to ar [default=autodetect]
  --with-ranlib=ARG       Use ARG as the path to ranlib [default=autodetect]
  --with-llc=ARG          Use ARG as the path to llc [default=autodetect]
  --with-opt=ARG          Use ARG as the path to opt [default=autodetect]

Some influential environment variables:
  CC_STAGE0   C compiler command (bootstrap)
  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>
  CPP         C preprocessor

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