| |
| # 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) |
| # 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 |
| # SHLIB_EXPORTS (optional) Name of file containing list of symbols to |
| # export, in the format "function_name number" |
| # |
| # When building a shared library, the following version information |
| # must also be set. It should be omitted when building a dynamically |
| # loadable module. |
| # |
| # SO_MAJOR_VERSION Major version number to use for shared library |
| # SO_MINOR_VERSION Minor version number to use for shared library |
| # (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) |
| # installdirs-lib create installation directory $(libdir) |
| # uninstall-lib remove the libraries from $(libdir) |
| # clean-lib delete the static and shared libraries from the build dir |
| # maintainer-clean-lib delete .def files built for win32 |
| # |
| # 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. |
