ROOT-CONFIG(1)

NAME
root-config - ROOT utility for your Makefiles

SYNOPSIS
root-config [options]

DESCRIPTION
Put lines like
    CFLAGS = $(shell root-config --cflags)
    LIBS   = $(shell root-config --libs)
    GLIBS  = $(shell root-config --glibs)
    %Cint.cxx:Include.h LinkDef.h
            rootcint -f $@ -c $^
in you Makefile.

You may also find the automake(1), autoconf(1), and libtool(1) macro file /usr/share/aclocal/root.m4 useful. If that macro file isn't installed where Iaclocal will find it, copy the contents to your local acinclude.m4 file. In the directories you use ROOT libraries, have in your Makefile.am file:
    lib_LTLIBRARIES         = libFoo.la
    pkginclude_HEADERS      = Foo.h
    noinst_HEADERS          = FooCint.h
    libFoo_la_SOURCES       = Foo.cxx FooCint.cxx
    libFoo_la_LDFLAGS       = -version-info 1:0 -R @ROOTLIBDIR@
    libFoo_la_LDADD         = -lCore -lCint @ROOTAUXLIBS@
    BUILT_SOURCES           = FooCint.cxx FooCint.h
    AM_CPPFLAGS             = -I@ROOTINCDIR@
    AM_LDFLAGS              = -L@ROOTLIBDIR@
    CLEANFILES              = *Cint.cxx *Cint.h *~ core
    %Cint.cxx %Cint.h:Include.h LinkDef.h
            @ROOTCINT@ -f $*Cint.cxx -c $(INCLUDES) $(AM_CPPFLAGS) $^
where you should substitute Foo with whatever, and list the appropiate source files in the _SOURCES variable. In you configure.in file, put:
    AC_PROG_CC
    AC_PROG_CXX
    ROOT_PATH
    AM_PROG_LIBTOOL
along with any other macros you may need.

Note that the ROOT_PATH macro takes three optional arguments: the minimal ROOT version to use, action if ROOT is found, and action if ROOT isn't found. Some examples are
    ROOT_PATH(3.03/05, , AC_MSG_ERROR(Your ROOT version is too old))
    ROOT_PATH(, AC_DEFUN(HAVE_ROOT))
For example, if you want to compile some part of your source tree conditionally on wether ROOT is present or not, you can put in your configure.in file
    ROOT_PATH(,
    [
      AC_DEFUN(HAVE_ROOT)
      have_root=yes
    ])
    AM_CONDITIONAL(GOT_ROOT, test "x$have_root" = "xyes")
And then in some Makefile.am
    EXTRA_SOURCES		= root_depenent_source.cc
    if GOT_ROOT
    LIBFOOXTRA              = root_depenent_source.cc
    else
    LIBFOOXTRA              =
    endif
    lib_LTLIBRARIES         = libFoo.la
    libFoo_la_SOURCES	= Foo.cc  $(LIBFOOXTRA)
The full list of substitution variables are:

ROOTCONF
    full path to root-config

ROOTEXEC
    full path to root

ROOTCINT
    full path to rootcint

ROOTLIBDIR
    Where the ROOT libraries are

ROOTINCDIR
    Where the ROOT headers are

ROOTCFLAGS
    Extra compiler flags

ROOTLIBS
    ROOT basic libraries

ROOTGLIBS
    ROOT basic + GUI libraries

ROOTAUXLIBS
    Auxilary libraries and linker flags for ROOT

ROOTAUXCFLAGS
    Auxilary compiler flags

ROOTRPATH
    Same as ROOTLIBDIR

OPTIONS

--help
    Gives a short list of options avaliable, and exit

--version
    Report the version number of installed ROOT, and exit.

--prefix=<prefix>
    If no arguments is given, reports where ROOT is installed. With an argument of =<prefix>, set the base of the subsequent options to <prefix>. If \--exec-prefix is passedwith an argument, that argument overrides the argument given to \--prefix for the library path.

--exec-prefix=<prefix>
    If no argument is given, report where the libraries are installed. If an argument is given, use that as the installation base directory for the libraries. This option does not affect the include path.

--libdir
    Print the directory where the ROOT libraries are installed.

--incdir
    Print the directory where the ROOT headers are installed.

--libs
    Output a line suitable for linking a program agains the ROOT libraries. No graphics libraries are output.

--glibs
    As above, but also output for the graphics libraries.

--cflags
    Output a line suitable for compiling a source file againd the ROOT header (class declararion) files.

--new
    Put the libNew.so library in the library lists. This option must be given before options --libs and --glibs.

--nonew
    Compatiblity option. Does nothing.

--auxlibs
    Print auxiliary libraries and/or system linker flags.

--noauxlibs
    Do not print auxiliary libraries and/or system linker flags in the output of --libs and --glibs. --auxcflags Print auxiliary compiler flags.

--noauxcflags
    Do not print auxiliary compiler flags in the output of --cflags.

--noldflags
    Do not print library path link option in output of --libs and --glibs.
