#
# 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_LINK Stuff to append to library's link command
+# (typically, -L and -l switches for external libraries)
+# SHLIB_LINK_INTERNAL -L and -l switches for Postgres-supplied libraries
# SHLIB_PREREQS Order-only prerequisites for library build target
# SHLIB_EXPORTS (optional) Name of file containing list of symbols to
# export, in the format "function_name number"
#
+# Don't use SHLIB_LINK for references to files in the build tree, or the
+# wrong things will happen --- use SHLIB_LINK_INTERNAL for those!
+#
# When building a shared library, the following version information
# must also be set. It should be omitted when building a dynamically
# loadable module.
# 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.)
# 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:
+# Typically you would add `all-lib' to the `all' target so that `make all'
+# builds the libraries. In the most simple case it would look like this:
#
# all: all-lib
#
#
# 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.
