Ticket #1668 (closed bug: fixed)
build system incorrectly includes build.mk unconditionally
./libraries/base/Makefile.local unconditionally includes $(TOP)/mk/build.mk when in fact it should do something more along the lines of the following:
ifeq "$(Validating)" "YES" include $(TOP)/mk/validate-settings.mk -include $(TOP)/mk/validate.mk else -include $(TOP)/mk/build.mk # (Optional) build-specific configuration # endif
This error causes validation to fail when build.mk contains -Werror, as there are things within libraries/base which have not yet been caused to be warning-clean.
Here is a subset of files that mention build.mk and may be worth investigating:
./configure.ac ./distrib/cross-port ./distrib/hc-build ./mk/boilerplate.mk ./mk/config.mk ./mk/config.mk.in ./mk/install.mk ./mk/build.mk ./mk/build.mk.sample ./bindisttest/Makefile ./compiler/ghci/keepCAFsForGHCi.c ./compiler/ilxGen/tests/Makefile ./compiler/ndpFlatten/TODO ./libraries/base/Makefile.local ./libraries/Makefile.local ./libraries/Makefile ./WindowsInstaller/MakeInstaller.txt ./Makefile
