  13 # This file should be included by any Postgres module Makefile that
  14 # wants to build a shared library (if possible for the current
  15 # platform). A static library is also built from the same object
  16 # files. Only one library can be built per makefile.
  17 #
  18 # Before including this file, the module Makefile must define these
  19 # variables:
  20 #
  21 # NAME                  Name of library to build (no suffix nor "lib" prefix)
  22 # SO_MAJOR_VERSION      Major version number to use for shared library
  23 # SO_MINOR_VERSION      Minor version number to use for shared library
  24 # OBJS                  List of object files to include in library
  25 # SHLIB_LINK            If shared library relies on other libraries,
  26 #                       additional stuff to put in its link command
  27 # (If you want a patchlevel, include it in SO_MINOR_VERSION, e.g., "6.2".)
  28 #
  29 # Optional flags when building DLL's (only applicable to win32 and cygwin
  30 # platforms).
  31 # DLLTOOL_DEFFLAGS      Additional flags when creating the dll .def file
  32 # DLLTOOL_LIBFLAGS      Additional flags when creating the lib<module>.a file
  33 # DLLWRAP_FLAGS         Additional flags to dllwrap
  34 #
  35 # The module Makefile must also include
  36 # $(top_builddir)/src/Makefile.global before including this file.
  37 # (Makefile.global sets PORTNAME and other needed symbols.)
  38 #
  39 # This makefile provides the following (phony) targets:
  40 #
  41 # all-lib               build the static and shared (if applicable) libraries
  42 # install-lib           install the libraries into $(libdir)
  43 # uninstall-lib         remove the libraries from $(libdir)
  44 # clean-lib             delete the static and shared libraries from the build dir
  45 #
  46 # Since `all-lib' is the first rule in this file you probably want to
  47 # have the `all' target before including this file. In the most simple
  48 # case it would look like this:
  49 #
  50 #     all: all-lib
  51 #
  52 # Similarly, the install rule might look like
  53 #
  54 #     install: install-lib
  55 #
  56 # plus any additional things you want to install. Et cetera.
  57 #
  58 # Got that?  Look at src/interfaces/libpq/Makefile for an example.
  59 #
  60 # While the linker allows creation of most shared libraries,
  61 # -Bsymbolic requires resolution of all symbols, making the
  62 # compiler a better choice for shared library creation on ELF platforms.
  63 # With the linker, -Bsymbolic requires the crt1.o startup object file.
