configure

#!/bin/bash
#
# A (not so) simple configure script.
#
# Authors: Christian Holm Christensen and Fons Rademakers.
#
# To help with debugging the script, some comments are preprended with
# 3 '#' echo and 3 '%' - replace that pattern with echo and 3 '%' to
# get printouts.  When done replace the pattern echo and 3 '%' with the
# original pattern of 3 '#' echo and 3 '%'.  Emacs command M-C-% does
# this easily.

'configure' configures ROOT $vers to adapt to many kind of systems.

Usage:     $0 [architecture] [flag=value]

The architecture to build for will be guessed from the output of 'uname'.
If, however, that fails, or you don't want the 'native' compiler on the
host platform, you can specify the architecture to use by passing as the
FIRST argument one of the architecures given at the end of this message.

   FLAG            DESCRIPTION               DEFAULT
   --aclocaldir    Autoconf macro install dir(<prefix>/share/aclocal)
   --bindir        Binary installation dir   (<prefix>/bin)
   --build         Build configuration [debug, ...],
                   overrides the ROOTBUILD shell variable
   --cflags        Flags to pass to the C compiler that change the ABI, none by default
   --cxxflags      Flags to pass to the C++ compiler that change the ABI, none by default
   --datadir       Data installation dir     (<prefix>/share/root)
   --docdir        Documentation             (<prefix>/share/doc/root)
   --elispdir      Where to put Emacs Lisp   (<prefix>/share/emacs/site-lisp)
   --etcdir        Config installation dir   (<prefix>/etc/root)
   --fontdir       Font installation dir     (<datadir>/fonts)
   --iconpath      Icon installation dir     (<datadir>/icons)
   --incdir        Header installation dir   (<prefix>/include/root)
   --libdir        Library installation dir  (<prefix>/lib/root)
   --macrodir      Macro installation dir    (<datadir>/macros)
   --mandir        Manpages installation dir (<prefix>/share/man/man1)
   --no-create     Do not create output files, dry run
   --prefix        Installation prefix       (/usr/local)
   --srcdir        Sources installation dir  (<datadir>/src)
   --testdir       Tests                     (<docdir>/test)
   --tutdir        Tutorials                 (<docdir>/tutorial)

If any of the flags --datadir, --docdir, --etcdir, --iconpath
--incdir, --libdir, --macrodir, --mandir, or --prefix is given,
ROOT will be compiled with static directory names, and you should not set
the ROOTSYS environment variable.

To reduce the output of configure by removing the trailing howto message, use:

   --nohowto

Use the flag:

  --fail-on-missing

to force configure to fail if a component that has been explicitly enabled
is missing some dependencies and can not be built.
