# This script is just here to illustrate the procedure for preparing
# the configure process. It creates configuration files (ex:
# ltmain.sh) using libtoolize, the aclocal macro, the configure script
# using autoconf and some scripts used in building process (ex:
# install-sh) using automake. Automake is used here to creates the
# files Makefile.in from the files Makefile.am.

# CONF_DIR is the path containing the present script

# aclocal creates the aclocal.m4 file from the standard macro and the
# custom macro embedded in the directory salome_adm/unix/config_files.
# output:
#   aclocal.m4
#   autom4te.cache (directory)

# ____________________________________________________________________
# libtoolize creates some configuration files (ltmain.sh,
# config.guess and config.sub). It only depends on the libtool
# version. The files are created in the directory specified with the
# AC_CONFIG_AUX_DIR(<mydir>) tag (see configure.ac).
# output:
#   salome_adm/unix/config_files/config.guess
#   salome_adm/unix/config_files/config.sub
#   salome_adm/unix/config_files/ltmain.sh
echo "====================================================== libtoolize"

libtoolize --force --copy --automake || exit 1


# ____________________________________________________________________
# autoconf creates the configure script from the file configure.ac (or
# configure.in if configure.ac doesn't exist)
# output:
#   configure
echo "====================================================== autoconf"

# autoheader creates config.h.in

# automake creates some scripts used in building process
# (install-sh, missing, ...). It only depends on the automake
# version. The files are created in the directory specified with the
# AC_CONFIG_AUX_DIR(<mydir>) tag (see configure.ac). This step also
# creates the Makefile.in files from the Makefile.am files.
# output:
#   salome_adm/unix/config_files/compile
#   salome_adm/unix/config_files/depcomp
#   salome_adm/unix/config_files/install-sh

#
# Note that automake could be executed at last after autoconf. The
# order doesn't matter.
#
# When modifying a Makefile.am file, after a first step of
# configure+make, you just have to :
# - go to the top source directory and run automake, to rebuild the Makefile.in,
# - go to the top build directory and run config.status to rebuild the
#   Makefile from the Makefile.in,
# - go to the source directory being modified, and then run make.
