What should work (on Linux at least): {{{ git checkout wip/transformers-0.5.2 git submodule update ./validate --fast }}} If you look at `git show wip/transformers-0.5.2` you'll notice that the only thing needed is to update the transformers submodule and silence a warning accidentally introduced by `transformers`: {{{#!diff diff --git a/libraries/transformers b/libraries/transformers index a2f7dd0..10348c4 160000 --- a/libraries/transformers +++ b/libraries/transformers @@ -1 +1 @@ -Subproject commit a2f7dd057a0ee0c6cb206609594d7a07d26a1861 +Subproject commit 10348c4bbf60debbfc82463e1035aca1cb7b51bc diff --git a/mk/warnings.mk b/mk/warnings.mk index 10c0935..63388fb 100644 --- a/mk/warnings.mk +++ b/mk/warnings.mk @@ -104,6 +104,7 @@ libraries/dph/dph-lifted-common-install_EXTRA_HC_OPTS += -Wwarn libraries/transformers_dist-boot_EXTRA_HC_OPTS += -fno-warn-unused- matches -fno-warn-unused-imports libraries/transformers_dist-install_EXTRA_HC_OPTS += -Wno-unused-matches -Wno-unused-imports libraries/transformers_dist-install_EXTRA_HC_OPTS += -Wno-redundant- constraints +libraries/transformers_dist-install_EXTRA_HC_OPTS += -Wno-orphans # Turn of trustworthy-safe warning libraries/base_dist-install_EXTRA_HC_OPTS += -Wno-trustworthy-safe }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11600#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
