Re: Happy / Alex description for Haskell2010
Thanks Doaitse, I'm not looking for a parser that I can run, I am mostly interested in the codified BNF, to study, and adapt. I'll take a look at the Utrecht Haskell Compiler in any case, as it sounds interesting... do you mean this file? https://github.com/uhc/uhc/blob/master/EHC/src/helium/Parser/Parser.hs On Thu, 25 Oct 2018 at 20:11, Doaitse Swierstra wrote: > > I do not know why you do need a Haskell parser, but the Utrecht Haskell > Compiler contains a combinator based Haskell parser (using the uulib package, > supporting the offside rule) which might serve your needs.

Happy / Alex description for Haskell2010
Hello all, Is there a Happy / Alex file describing Haskell2010? I can see the versions in the ghc source tree, but of course they support all the ghc extensions. The link to the hsparser page [1] in the Happy documentation doesn't seem to exist anymore. I would also love to hear if there is a Bison definition.

Re: Unable to compile ghc-8.2.2 with ghc-8.4.3
Hi Ben, Updating the new build tool is e right thing to do, long term, but it unfortunate doesn't help with my objective of compiling old versions of ghc ... but there is a quick here that I could exploit. Since I'm building for the same platform, bug just using different versions of the operating system, I think I can create the C files in an old Debian inside docker and use them in the more modern host machine to build the old ghc.

Re: Unable to compile ghc-8.2.2 with ghc-8.4.3
Hi Ben, This would definitely help. I could use a docker image of a really old OS that has old ghc binaries available, to generate the .c for that old version of GHC (e.g. v 7.0 or something). Then I could use those files to bootstrap a ghc 7.0 on my machine, and from there every version of ghc since. It would make a lot of sense for the "unregistered" sources to be made available as an optional download alongside the source code, if haskell.org were open to that possibility.

Re: Unable to compile ghc-8.2.2 with ghc-8.4.3
Hi Tom, I'm not sure it is necessary to go back that far. Vitaly pointed out that any version of GHC could produce the "minimal C" output, which can be ported to another platform that doesn't have a GHC, as the bootstrap. I'm not entirely sure how to generate that output, mind you.

Re: Unable to compile ghc-8.2.2 with ghc-8.4.3
Hi Ben, What is the recommended way to build old versions of GHC? The haskell.org binaries for, e.g. 7.8.3, do not work on my machine. If I attempt to recompile ghc 7.8.3 with the haskell.org binary, I get linkage errors. Actually I'd love to be able to bootstrap a build without any ghc installed... that would solve the problem. I heard about the "phase0" approach from Vitaly Bragilevsky at his Lambdaconf talk this year. But I've been unable to find any documentation about it.

Unable to compile ghc-8.2.2 with ghc-8.4.3
Hello all, I am unable to compile ghc-8.2.2 with ghc-8.4.3 (which is otherwise working fine, e.g. to compile my own projects and xmonad). Could somebody please help? The error I get is ghc-cabal: Encountered missing dependencies: base >=4.4.1 && <4.11 libraries/hpc/ghc.mk:3: libraries/hpc/dist-boot/package-data.mk: No such file or directory make[1]: *** [libraries/hpc/ghc.mk:3: libraries/hpc/dist-boot/package-data.mk] Error 1 make: *** [Makefile:123: all] Error 2 I should give some background as to why I'm doing this: I am trying to build a back catalogue of ghc installations because the older binary downloads from haskell.org give me linking errors and I've lost faith in Archlinux's ability to package ghc. I plan on using these builds of ghc in stack, instead of their binaries. I don't like downloading binaries. I'd rather build them from source. I will also create a docker image for my own CI purposes. I'm using this script, but it's just a formalisation of the ghc installation instructions to help me automate the process. https://gitlab.com/fommil/ghc-env/blob/master/bin/ghc-env I am on Archlinux, which (I'm sure many of you know) has a very broken concept of ghc. I already lost 2 hours today because Archlinux broke my ~/.ghc, and therefore xmonad was unable to start and this locked me out of my desktop. I plan on using NixOS in the future. From a fresh OS install I do pacman -S ghc-static cabal-install to get me ghc 8.4.3 and the cabal CLI. From here I download and compile ghc 8.4.3 and cabal-install with ghc-env compile 8.4.3 cabal install cabal-install xmonad xmonad-contrib and now I can delete Arch's versions of ghc (yay!). But from here, if I try to compile ghc 8.2.2 (with a view to compile all the way back to the 7.x series) I get the failure at the top. An alternative solution would be if there were instructions for a fabled "phase0" compile, which doesn't require a ghc bootstrap. Does anybody know anything about that?
