#-------------------------------------------------------------------------
|
|
|
|
# This file should be included by any Postgres module Makefile that wants
|
|
# to build a shared library (if possible for the current platform).
|
|
# A static library is also built from the same object files.
|
|
# RESTRICTION: only one library can be built per makefile...
|
|
|
|
# Before including this file, the module Makefile must define these variables:
|
|
# NAME Name of library to build (no suffix nor "lib" prefix)
|
|
# SO_MAJOR_VERSION Major version number to use for shared library
|
|
# SO_MINOR_VERSION Minor version number to use for shared library
|
|
# OBJS List of object files to include in library
|
|
# SHLIB_LINK If shared library relies on other libraries, additional
|
|
# stuff to put in its link command
|
|
# (If you want a patchlevel, include it in SO_MINOR_VERSION, eg, "6.2".)
|
|
#
|
|
# The module Makefile must also include $(SRCDIR)/Makefile.global before
|
|
# including this file (Makefile.global sets PORTNAME and other needed symbols).
|
|
#
|
|
# The first rule in this file is a rule for "all", which causes both the
|
|
# static and shared libraries to be built (as well as all the object files).
|
|
# If you have other files that need to be made before building object files
|
|
# and libraries, put another rule for "all" before you include this file.
|
|
#
|
|
# Your install rule should look like
|
|
#
|
|
# install: install-headers install-lib $(install-shlib-dep)
|
|
#
|
|
# where install-headers is only needed if you have header files to install
|
|
# (and, of course, it has to be provided by your makefile). The rules
|
|
# install-lib and install-shlib are provided by this makefile --- they
|
|
# automatically install the plain and shared libraries into $(LIBDIR).
|
|
# install-shlib-dep is a variable that expands to install-shlib if the
|
|
# shared library needs to be installed, empty if not.
|
|
#
|
|
# Got that? Look at src/interfaces/libpq/Makefile.in for an example.
|
|
|
|
|
|
# shlib and install-shlib-dep default to empty, and stay that way if we're
|
|
# on a platform where we don't know how to build a shared library.
|
|
shlib :=
|
|
install-shlib-dep :=
|
|
|
|
# For each platform we support shlibs on, set shlib and install-shlib-dep,
|
|
# and update flags as needed to build a shared lib. Note we depend on
|
|
# Makefile.global (or really Makefile.port) to supply DLSUFFIX and other
|
|
# symbols.
