# PGXS: PostgreSQL extensions makefile

# $PostgreSQL: pgsql/src/makefiles/pgxs.mk,v 1.15 2008/10/03 08:00:16 petere Exp $ 

# This file contains generic rules to build many kinds of simple
# extension modules.  You only need to set a few variables and include
# this file, the rest will be done here.
#
# Use the following layout for your Makefile:
#
#   [variable assignments, see below]
#   [custom rules, rarely necessary]
#
#   PG_CONFIG = pg_config
#   PGXS := $(shell $(PG_CONFIG) --pgxs)
#   include $(PGXS)
#
# The following variables can be set:
#
#   MODULES -- list of shared objects to be build from source file with
#     same stem (do not include suffix in this list)
#   DATA -- random files to install into $PREFIX/share/contrib
#   DATA_built -- random files to install into $PREFIX/share/contrib,
#     which need to be built first
#   DOCS -- random files to install under $PREFIX/doc/contrib
#   SCRIPTS -- script files (not binaries) to install into $PREFIX/bin
#   SCRIPTS_built -- script files (not binaries) to install into $PREFIX/bin,
#     which need to be built first
#   REGRESS -- list of regression test cases (without suffix)
#
# or at most one of these two:
#
#   PROGRAM -- a binary program to build (list objects files in OBJS)
#   MODULE_big -- a shared object to build (list object files in OBJS)
#
# The following can also be set:
#
#   EXTRA_CLEAN -- extra files to remove in 'make clean'
#   PG_CPPFLAGS -- will be added to CPPFLAGS
#   PG_LIBS -- will be added to PROGRAM link line
#   SHLIB_LINK -- will be added to MODULE_big link line
#   PG_CONFIG -- path to pg_config program for the PostgreSQL installation
#     to build against (typically just "pg_config" to use the first one in
#     your PATH)
#
# Better look at some of the existing uses for examples...
