Occasionally a build will fail with an error about a .so library being truncated; the reason was that we weren't tracking the dependencies of the GHC stage2 .so library correctly. >--------------------------------------------------------------- rules/build-package-way.mk | 8 ++++++-- 1 files changed, 6 insertions(+), 2 deletions(-) diff --git a/rules/build-package-way.mk b/rules/build-package-way.mk index 18ac917..a4b604f 100644 --- a/rules/build-package-way.mk +++ b/rules/build-package-way.mk @@ -28,6 +28,7 @@ $(call hs-objs,$1,$2,$3) $1_$2_$3_LIB = $1/$2/build/libHS$$($1_PACKAGE)-$$($1_$2_VERSION)$$($3_libsuf) $$($1_PACKAGE)-$($1_$2_VERSION)_$2_$3_LIB = $$($1_$2_$3_LIB) +# Note [inconsistent distdirs] # hack: the DEPS_LIBS mechanism assumes that the distdirs for packages # that depend on each other are the same, but that is not the case for # ghc where we use stage1/stage2 rather than dist/dist-install. @@ -37,8 +38,11 @@ ifeq "$$($1_PACKAGE) $2" "ghc stage2" $$($1_PACKAGE)-$($1_$2_VERSION)_dist-install_$3_LIB = $$($1_$2_$3_LIB) endif -# All the .a/.so library file dependencies for this library -$1_$2_$3_DEPS_LIBS=$$(foreach dep,$$($1_$2_DEPS),$$($$(dep)_$2_$3_LIB)) +# All the .a/.so library file dependencies for this library. +# +# The $(subst stage2,dist-install,..) is needed due to Note +# [inconsistent distdirs]. +$1_$2_$3_DEPS_LIBS=$$(foreach dep,$$($1_$2_DEPS),$$($$(dep)_$(subst stage2,dist-install,$2)_$3_LIB)) ifeq "$$(BootingFromHc)" "YES" $1_$2_$3_C_OBJS += $$(shell $$(FIND) $1/$2/build -name "*_stub.c" -print | sed 's/c$$$$/o/') _______________________________________________ Cvs-ghc mailing list Cvs-ghc@haskell.org http://www.haskell.org/mailman/listinfo/cvs-ghc
