|> developers so we are sure it will work on all platforms. The problem with the current settings is that the linker is called directly. This is wrong, it should always be called through the compiler driver (the only exception is `ld -r'). This will make sure that the necessary libraries like libgcc are linked in. But there is still a different problem with the setting of LDFLAGS_ODBC. The psqlodbc module defines the functions _init and _fini which are reserved for the shared library initialisation. These should be changed to constructor functions. Then LDFLAGS_ODBC can be changed to be just `-lm'. Btw, why does it use -Bsymbolic? Andreas Schwab

#-------------------------------------------------------------------------

|
|
|
# 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...
