Note that if you want to use HEAD to build HEAD, then the only supported version is the one that you are building (e.g. you can use today's HEAD to build today's HEAD, but not to build tomorrow's HEAD).
Hi Ian, this is interesting, I built with a week old 7.7, with today's one there was no error.
Okay to push to master?
As long as it would still build with 7.4, sure.
It does with ghc-7.4.2, so I pushed it to ghc-head. I think a submodule update is in order, which I'll try to perform and come bad whining if it does not work out :-) The second patch needs a rework, I get this with 7.4.2: HC [stage 0] libraries/binary/dist-boot/build/Data/Binary/Builder/Base.o libraries/binary/src/Data/Binary/Builder/Base.hs:69:1: Warning: In the use of `unsafePerformIO' (imported from Foreign): Deprecated: "Use System.IO.Unsafe.unsafePerformIO instead; This function will be removed in the next release" So possibly a common fix for >=7.4 is possible. I try to come up with one.
But actually, GHC back at least as far as 7.4 shipped with binary, so I don't think we need to build it with the bootstrapping compiler any more. Does the build go through if you just remove binary from "PKGS_THAT_BUILD_WITH_STAGE0" in ghc.mk instead?
Yeah, looks like binary is not needed (tried with a HEAD bootstrap). Will confirm with ghc-7.4.2 and push when ok. Thanks for the tips, Gabor
Thanks Ian
