#-------------------------------------------------------------------------
|
|
|
|
# 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.
