ROOT-CONFIG(1) General Commands Manual ROOT-CONFIG(1) NAME root-config - ROOT utility for your Makefiles SYNOPSIS root-config [options] DESCRIPTION root-config is a tool that is used to configure and determine the compiler and linker flags that should be used to compile and link programs that use ROOT. CPPFLAGS += $(shell root-config --cflags) LDLIBS += $(shell root-config --libs) LDFLAGS += $(shell root-config --ldflags) %Cint.cxx:Include.h LinkDef.h rootcint -f $@ -c $^ in your Makefile to use the built-in rules of GNU make. For GUIs, replace --libs by --glibs. 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 aclocal 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) $^ where you should substitute Foo with whatever, and list the appropriate source files in the _SOURCES variable. In you configure.in file, put: AC_PROG_CC AC_PROG_CXX ROOT_PATH AM_PROG_LIBTOOL along with any other macros you may need. Note that the ROOT_PATH macro takes three optional arguments: the minimal ROOT version to use, action if ROOT is found, and action if ROOT isn't found. Some examples are ROOT_PATH(3.03/05, , AC_MSG_ERROR(Your ROOT version is too old)) ROOT_PATH(, AC_DEFUN(HAVE_ROOT)) For example, if you want to compile some part of your source tree condi- tionally on wether ROOT is present or not, you can put in your configure.in file ROOT_PATH(, [ AC_DEFUN(HAVE_ROOT) have_root=yes ]) AM_CONDITIONAL(GOT_ROOT, test "x$have_root" = "xyes") And then in some Makefile.am EXTRA_SOURCES = root_dependent_source.cc if GOT_ROOT LIBFOOXTRA = root_dependent_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 Auxiliary libraries and linker flags for ROOT ROOTAUXCFLAGS Auxiliary compiler flags ROOTRPATH Same as ROOTLIBDIR OPTIONS --help Give a short list of options available, and exit --version Report the version number of installed ROOT, and exit. --prefix=<prefix> If no arguments are given, reports where ROOT is installed. With an argument of =<prefix>, set the base of the subsequent options to <prefix>. If \--exec-prefix is passed with an argument, it 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 against the ROOT li- braries. No graphics libraries are included. --glibs As above, but also output for the graphics (GUI) libraries. --evelibs As above, but also output for the graphics libraries and Eve li- braries. --cflags Output a line suitable for compiling a source file against 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, --evelibs and --glibs. --ldflags Print additional linker flags (eg. -m64) --arch Print the architecture (compiler/OS) --platform Print the platform (OS) --bindir Print the binary directory of the root installation (location of the root executable) --etcdir Print the configuration directory (place of system.rootrc, mime type, valgrind suppression files and .desktop files) --config Print arguments used for ./configure as used when building root. These cannot be used for ./configure if root was built with CMake. --git-revision Print the ROOT git revision number from which root was built. --has-<feature> Test if <feature> has been enabled in the build process. --features Print list of all supported features --ncpu Print number of available (hyperthreaded) cores --python-version Print the Python version used by ROOT --cc Print alternative C compiler specified when ROOT was built --cxx Print alternative C++ compiler specified when ROOT was built --f77 Print alternative Fortran compiler specified when ROOT was built --ld Print alternative Linker specified when ROOT was built SEE ALSO root(1), root-cint(1) See also the ROOT webpages: http://root.cern ORIGINAL AUTHORS The ROOT team (see web page above): Rene Brun and Fons Rademakers COPYRIGHT This library is free software; you can redistribute it and/or modify it un- der the terms of the GNU Lesser General Public License as published by the Free Software Foundation; either version 2.1 of the License, or (at your option) any later version.
