# How to use:
|
9 |
# This makefile can:
|
10 |
# 1. Create automatical .def file from list of objects
|
11 |
# 2. Create .dll from objects and .def file, either automatical, or your
|
12 |
# hand-written (maybe) file, which must have same basename as dll
|
13 |
# WARNING! There MUST be object, which name match dll's name. Make sux.
|
14 |
# 3. Create import library from .def (as for .dll, only its name required,
|
15 |
# not dll itself)
|
16 |
# By convention implibs for dll have .dll.a suffix, e.g. libstuff.dll.a
|
17 |
# Why not just libstuff.a? 'Cos that's name for static lib, ok?
|
18 |
# Process divided into 3 phases because:
|
19 |
# 1. Pre-existent .def possible
|
20 |
# 2. Generating implib is enough time-consuming
|
21 |
#
|
22 |
# Variables:
|
23 |
# DLL_LDLIBS - libs for linking dll
|
24 |
# DLL_LDFLAGS - flags for linking dll
|
25 |
#
|
26 |
# By using $(DLL_SUFFIX) instead of 'dll', e.g. stuff.$(DLL_SUFFIX)
|
27 |
# you may help porting makefiles to other platforms
|
28 |
#
|
29 |
# Put this file in your make's include path (e.g. main include dir, for
|
30 |
# more information see include section in make doc). Put in the beginning
|
31 |
# of your own Makefile line "include dll.mk". Specify dependences, e.g.:
|
32 |
#
|
33 |
# Do all stuff in one step
|
34 |
# libstuff.dll.a: $(OBJECTS) stuff.def
|
35 |
# stuff.def: $(OBJECTS)
|
36 |
#
|
37 |
# Steps separated, pre-provided .def, link with user32
|
38 |
#
|
39 |
# DLL_LDLIBS=-luser32
|
40 |
# stuff.dll: $(OBJECTS)
|
41 |
# libstuff.dll.a: $(OBJECTS)
