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