ROOT-CONFIG(1) General Commands Manual ROOT-CONFIG(1)
root-config - ROOT utility for your Makefiles
Put lines like
CFLAGS = $(shell root-config --cflags)
LIBS = $(shell root-config --libs)
GLIBS = $(shell root-config --glibs)
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) $^
where you should substitute Foo with whatever, and list the appropriate source files in the _SOURCES variable. In you configure.in file,
along with any other macros you may need.
Note that the ROOT_PATH macro takes three optional arguments: the minimal ROOT version to use, action if ROOT is found, and action if ROOT
isn't found. Some examples are
ROOT_PATH(3.03/05, , AC_MSG_ERROR(Your ROOT version is too old))
For example, if you want to compile some part of your source tree conditionally on wether ROOT is present or not, you can put in your con-
AM_CONDITIONAL(GOT_ROOT, test "x$have_root" = "xyes")
And then in some Makefile.am
EXTRA_SOURCES = root_depenent_source.cc
LIBFOOXTRA = root_depenent_source.cc
lib_LTLIBRARIES = libFoo.la
libFoo_la_SOURCES = Foo.cc $(LIBFOOXTRA)
The full list of substitution variables are:
full path to root-config
full path to root
full path to rootcint
Where the ROOT libraries are
Where the ROOT headers are
Extra compiler flags
ROOT basic libraries
ROOT basic + GUI libraries
Auxilary libraries and linker flags for ROOT
Auxilary compiler flags
Same as ROOTLIBDIR
--help Gives a short list of options available, and exit
Report the version number of installed ROOT, and exit.
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.
If no argument is given, report where the libraries are installed. If an argument is given, use that as the installation base direc-
tory for the libraries. This option does not affect the include path.
Print the directory where the ROOT libraries are installed.
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.
As above, but also output for the graphics libraries.
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.
Compatiblity option. Does nothing.
Print auxiliary libraries and/or system linker flags.
Do not print auxiliary libraries and/or system linker flags in the output of --libs and --glibs. --auxcflags Print auxiliary com-
Do not print auxiliary compiler flags in the output of --cflags.
Do not print library path link option in output of --libs and --glibs.
