# dll.mk - auxilary Makefile to easy build dll's for mingw32 target
# ver. 0.6 of 1999-03-25
#
# Homepage of this makefile - http://www.is.lg.ua/~paul/devel/
# Homepage of original mingw32 project -
# http://www.fu.is.saga-u.ac.jp/~colin/gcc.html
#
# How to use:
# This makefile can:
# 1. Create automatical .def file from list of objects
# 2. Create .dll from objects and .def file, either automatical, or your
# hand-written (maybe) file, which must have same basename as dll
# WARNING! There MUST be object, which name match dll's name. Make sux.
# 3. Create import library from .def (as for .dll, only its name required,
# not dll itself)
# By convention implibs for dll have .dll.a suffix, e.g. libstuff.dll.a
# Why not just libstuff.a? 'Cos that's name for static lib, ok?
# Process divided into 3 phases because:
# 1. Pre-existent .def possible
# 2. Generating implib is enough time-consuming
#
# Variables:
# DLL_LDLIBS - libs for linking dll
# DLL_LDFLAGS - flags for linking dll
#
# By using $(DLL_SUFFIX) instead of 'dll', e.g. stuff.$(DLL_SUFFIX)
# you may help porting makefiles to other platforms
#
# Put this file in your make's include path (e.g. main include dir, for
# more information see include section in make doc). Put in the beginning
# of your own Makefile line "include dll.mk". Specify dependences, e.g.:
#
# Do all stuff in one step
# libstuff.dll.a: $(OBJECTS) stuff.def
# stuff.def: $(OBJECTS)
#
# Steps separated, pre-provided .def, link with user32
#
# DLL_LDLIBS=-luser32
# stuff.dll: $(OBJECTS)
# libstuff.dll.a: $(OBJECTS)
