# (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
+# DLL_DEFFILE Use pre-existing .def file instead of auto-generating
+# one with all exports in it (win32 only).
+#
# The module Makefile must also include
# $(top_builddir)/src/Makefile.global before including this file.
# (Makefile.global sets PORTNAME and other needed symbols.)
# 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.
