# module Makefile
#(to be included from each module)
#
# History:
# --------
#  2007-03-29  if a module depends on SER_LIBS, it will be rebuilt on install
#               with the proper rpath; libraries will be automatically
#               installed if needed (andrei)
#  2008-06-23  added the README & man targets (andrei)
#  2008-06-27  make cfg / config.mak support (andrei)
#  2009-03-10  replaced DEFS with C_DEFS and INCLUDES with C_INCLUDES (DEFS
#              and INCLUDES are now used only for "temporary" defines/includes
#              inside modules or libs) (andrei)
#  2009-10-01  added support for automatically installing extra utils,
#               scripts and cfg files (andrei)
#  2010-03-04  don't overwrite already installed .cfgs, save the .cfg as
#              .sample in this case (andrei)
#

#
# Variables that should be defined in the modules, prior to including
# this makefile:
#
# NAME - module binary name, complete with .so and no path (MUST).
#
# COREPATH - path to the main/core directory (OPTIONAL, default ../..)
#
# DEFS - per module extra defines (OPTIONAL)
#
# LIBS - per module extra libs (OPTIONAL)
#
# SER_LIBS - ser/sr libs that should be compiled, linked against and installed
#           along the module. The format is: <path>/<shortname>, e.g.
#           SER_LIBS=../../lib/srdb2/srdb2 for libsrdb2 with the sources
#            in ../../lib/srdb2. (OPTIONAL)
#
# MOD_INSTALL_UTILS - list of utils directories that should be compiled and
#                     installed along the module. The utils must know how to
#                     install themselves (make install).
#                     E.g.: MOD_INSTALL_UTILS=../../utils/sercmd
#                     (OPTIONAL)
#
# MOD_INSTALL_SCRIPTS - list of scripts (complete path including the file name)
#                       that should be installed along the module.
#                       E.g.: MOD_INSTALL_SCRIPTS=../../scripts/foo/foo.sh
#                       (OPTIONAL)
#
# MOD_INSTALL_CFGS - list of extra config files that should be installed in
#                    the main config directory, along the module (OPTIONAL).
#
# MOD_INSTALL_SHARE - list of files to install into the arch-independent
#                     shared directory (by default
#                     /usr/local/share/$(MAIN_NAME))
