postgresql/src/Makefile.shlib
Peter Eisentraut 335248c9b7 Support for DESTDIR make variable. This is used as in `make install 
DESTDIR=/else/where' and prepends the value of DESTDIR to the full
installation paths (e.g., /else/where/usr/local/pgsql/bin). This allows
users to install the package into a location different from the one that
was configured and hard-coded into various scripts, e.g., for creating
binary packages.

DESTDIR is in many cases preferrable over `make install
prefix=/else/where' because

a) `prefix' affects the path that is hard-coded into the files, which can
lead to a `make install prefix=xxx' (as done by the regression test
driver) corrupting the files in the source tree with wrong paths.

b) it doesn't work at all if a directory was overridden to not depend on
`prefix', e.g., --sysconfdir=/etc.

(Updating the regression test driver to use DESTDIR is a separate
undertaking.)

#-------------------------------------------------------------------------
# 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".)
#
# 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.
# shlib is empty by default. If we know how to build a shared library
# it will contain the name of the file, otherwise it will remain
# empty. Thus `ifdef shlib' could be used in the containing make file
# to test whether shared libraries are available.
shlib :=
# For each platform we support shared libraries on, set shlib 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.
# Try to keep the sections in some kind of order, folks...
