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.
