|
|
|
27 Here's the scoop. We would really like this to be a shell script, but
|
|
|
28 the various Windows platforms don't have reliable scripting that suits
|
|
|
29 our needs. We don't want to rely on perl or some other such language
|
|
|
30 so we have to roll our own executable to act as a front-end for the
|
|
|
31 compiler.
|
|
|
32
|
|
|
33 This program is used to invoke the compiler, the linker and to generate
|
|
|
34 the module specific documentation and initialization code. We assume we
|
|
|
35 are in 'compile' mode unless we encounter an argument which tells us
|
|
|
36 that we're not. We take all arguments and pass them on directly to the
|
|
|
37 compiler, except for a few which are specific to this program:
|
|
|
38
|
|
|
39 --mode=VALUE This sets the program mode. VALUE can be one of
|
|
|
40 compile, link, init or verbose.
|
|
|
41 --mod-name=NAME Sets the module name to the string NAME.
|
|
|
42 --mod-title=TITLE Sets the module title to the string TITLE.
|
|
|
43 --mod-version=VER Sets the module version to the string VER.
|
|
|
44
|
|
|
45 The idea is that Makefiles will use ellcc as the compiler for making
|
|
|
46 dynamic Emacs modules, and life should be as simple as:
|
|
|
47
|
|
|
48 make CC=ellcc LD='ellcc --mode=link'
|
|
|
49
|
|
|
50 The only additional requirement is an entry in the Makefile to produce
|
|
|
51 the module initialization file, which will usually be something along
|
|
|
52 the lines of:
|
|
|
53
|
|
|
54 modinit.c: $(SRCS)
|
|
|
55 ellcc --mode=init --mod-name=\"$(MODNAME)\" \
|
|
|
56 --mod-title=\"$(MODTITLE)\" --mod-version=\"$(MODVERSION)\" \
|
|
|
57 -o $@ $(SRCS)
|
|
|
58
|
|
|
59 See the samples for more details.
