postgresql/src/Makefile.shlib
Tom Lane 9df3086972 Cause libpq and ecpg libraries to be built as proper shared libraries 
(.dylib format) on Mac OS X, while not messing up loadable modules for
the backend (which are the same kind of animal as a shared library on
every other platform, but not here).  Also get the naming convention
to match OS X practice, viz libFOO.version.so not libFOO.so.version.
In support of that last, refactor code in Makefile.shlib to make it
easier to have platform-specific shlib naming conventions.
This patch is loosely based on the Fink project's current postgresql.patch.
Tested by yours truly on OS X 10.3.4; does anyone have 10.2.* to check
it on?

#-------------------------------------------------------------------------
# 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. 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, e.g., "6.2".)
#
# Optional flags when building DLL's (only applicable to win32 and cygwin
# platforms).
# DLLTOOL_DEFFLAGS Additional flags when creating the dll .def file
# DLLTOOL_LIBFLAGS Additional flags when creating the lib<module>.a file
# DLLWRAP_FLAGS Additional flags to dllwrap
#
# The module Makefile must also include
# $(top_builddir)/src/Makefile.global before including this file.
# (Makefile.global sets PORTNAME and other needed symbols.)
#
# This makefile provides the following (phony) targets:
#
# all-lib build the static and shared (if applicable) libraries
# install-lib install the libraries into $(libdir)
# uninstall-lib remove the libraries from $(libdir)
# clean-lib delete the static and shared libraries from the build dir
#
# Since `all-lib' is the first rule in this file you probably want to
# have the `all' target before including this file. In the most simple
# case it would look like this:
#
# all: all-lib
#
# Similarly, the install rule might look like
#
# install: install-lib
#
# plus any additional things you want to install. Et cetera.
#
# Got that? Look at src/interfaces/libpq/Makefile for an example.
#
# While the linker allows creation of most shared libraries,
# -Bsymbolic requires resolution of all symbols, making the
# compiler a better choice for shared library creation on ELF platforms.
# With the linker, -Bsymbolic requires the crt1.o startup object file.
