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

99 # That means that if you modify a .hi-boot file in Windows, you
