39 # Bootstrapping

41 # The stage1/stage2/stage3 business is quite delicate. Here's how it works:
42 #
43 # - the variable $(stage) holds the current stage number. To build a
44 # particular stage, you say 'make stage=N' where N is 1, 2, or 3.
45 # N defaults to 1.
46 #
47 # - for stage N, object files and .hi files are placed inside
48 # the directory stageN, in subdirectories as per the sources.
49 #
50 # - .hi-boot files are *linked* into the stageN tree, because in GHC 5.05+
51 # the .hi-boot file must reside in the same place as the .hi file.
52 #
53 # - we use explicit -o and -ohi options to direct the output from C &
54 # Haskell compilations.
55 #
56 # - we generate a different .depend file for each build. They need to be
57 # different, because each stage might include different files: stage1
58 # might not include GHCi, for example. For each stage, a normal .depend
59 # file is generated, and then post-processed to add the correct stageN/
60 # prefix to each object and .hi filename. The resulting .depend file
61 # is named .depend-$(stage). See the end of this Makefile for details.
62 #
63 # - normal implicit rules don't work any more, because they're of the form
64 #
65 # %.o : %.hs
66 #
67 # whereas we really need
68 #
69 # stageN/%.o : %.hs
70 #
71 # so suffix.mk now defines the appropriate suffix rules when
72 # $(odir) is set to a non-empty value. Here we set $(odir) to
73 # stage1, stage2, or stage3.
74 #
75 # There are other plausible designs that might work, but each has different
76 # problems:
77 #
78 # - using -odir and -hidir: GHC <= 4.08 doesn't support -hidir, and
79 # anyway -odir puts all the objects in one directory (strips off the
80 # subdirectory part), which eventually forces us to use VPATH to find
81 # the sources. I have a really bad feeling about VPATH.
82 #
83 # - invoke make in the stageN subdirectory. This probably requires VPATH
84 # too.
85 #
86 # - create a link tree. The problem with requiring link trees is that
87 # Windows doesn't support symbolic links.
