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.
18 # Before including this file, the module Makefile must define these
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".)
29 # Optional flags when building DLL's (only applicable to win32 and cygwin
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 # DLL_DEFFILE Use pre-existing .def file instead of auto-generating
35 # one with all exports in it (win32 only).
37 # The module Makefile must also include
38 # $(top_builddir)/src/Makefile.global before including this file.
39 # (Makefile.global sets PORTNAME and other needed symbols.)
41 # This makefile provides the following (phony) targets:
43 # all-lib build the static and shared (if applicable) libraries
44 # install-lib install the libraries into $(libdir)
45 # uninstall-lib remove the libraries from $(libdir)
46 # clean-lib delete the static and shared libraries from the build dir
48 # Since `all-lib' is the first rule in this file you probably want to
49 # have the `all' target before including this file. In the most simple
50 # case it would look like this:
54 # Similarly, the install rule might look like
56 # install: install-lib
58 # plus any additional things you want to install. Et cetera.
60 # Got that? Look at src/interfaces/libpq/Makefile for an example.
62 # While the linker allows creation of most shared libraries,
63 # -Bsymbolic requires resolution of all symbols, making the
64 # compiler a better choice for shared library creation on ELF platforms.
65 # With the linker, -Bsymbolic requires the crt1.o startup object file.
