Build system: renable -Wall on validate (base)

13 # ToDo List.
14 #
15 # * remove old Makefiles, add new stubs for building in subdirs
16 # * docs/Makefile
17 # * docs/storage-mgmt/Makefile
18 # * docs/vh/Makefile
19 # * rts/dotnet/Makefile
20 # * utils/Makefile
21 # * add Makefiles for the rest of the utils/ programs that aren't built
22 # by default (need to exclude them from 'make all' too)
23
24 # Possible cleanups:
25 #
26 # * per-source-file dependencies instead of one .depend file?
27 # * eliminate undefined variables, and use --warn-undefined-variables?
28 # * put outputs from different ways in different subdirs of distdir/build,
29 # then we don't have to use -osuf/-hisuf. We would have to install
30 # them in different places too, so we'd need ghc-pkg support for packages
31 # of different ways.
32 # * make PACKAGES_STAGE1 generated by './configure' or './boot'?
33 # * we should use a directory of package.conf files rather than a single
34 # file for the inplace package database, so that we can express
35 # dependencies more accurately. Otherwise it's possible to get into
36 # a state where the package database is out of date, and the build
37 # system doesn't know.
38
39 # Approximate build order.
40 #
41 # The actual build order is defined by dependencies, and the phase
42 # ordering used to ensure correct ordering of makefile-generation; see
43 # http://ghc.haskell.org/trac/ghc/wiki/Building/Architecture/Idiom/PhaseOrdering
44 #
45 # * With bootstrapping compiler:
46 # o Build utils/ghc-cabal
47 # o Build utils/ghc-pkg
48 # o Build utils/hsc2hs
49 # o Build utils/genprimopcode
50 # o Build utils/deriveConstants
51 # * For each package:
52 # o configure, generate package-data.mk and inplace-pkg-config
53 # o register each package into inplace/lib/package.conf
54 # * build libffi (if not disabled by --with-system-libffi)
55 # * With bootstrapping compiler:
56 # o Build libraries/{filepath,hpc,Cabal}
57 # o Build compiler (stage 1)
58 # * With stage 1 compiler:
59 # o Build libraries/*
60 # o Build rts
61 # o Build utils/* (except haddock)
62 # o Build compiler (stage 2)
63 # * With stage 2 compiler:
64 # o Build utils/haddock
65 # o Build compiler (stage 3) (optional)
66 # * With haddock:
67 # o libraries/*
68 # o compiler

1463 # - when Stage1Only=YES, it's clear that ghc-stage2 is not available (we just
1464 # said we didn't want it), so we have to exclude the stage2 packages from
1465 # the build. This includes the case where Stage1Only=YES is combined with
1466 # CrossCompiling=YES (Building GHC as a cross-compiler [3]).
1467 # - when CrossCompiling=YES, but Stage1Only=NO (Cross-compiling GHC itself
1468 # [3]), we can not use ghc-stage2 either. The reason is that stage2 doesn't
1469 # run on the host platform at all; it is built to run on $(TARGETPLATFORM)"
1470 # [5]. Therefore in this case we also have to exclude the stage2 packages
1471 # from the build.
