Ben and other friends What is the approved way to build libraries with (and for) a compiler that I've just built? I tried this: bash$ cabal v2-install --with-ghc=/home/simonpj/code/ghc-9.2-branch/inplace/bin/ghc-stage2 streamly --allow-newer but it failed with Data/Primitive/Types.hs:273:844: error: * Couldn't match expected type 'Word#' with actual type 'Word8#' * In the fourth argument of 'shimmedSetWord8Array#', namely 'x#' (This was for a compiler built from the ghc-9.2 branch.) I'd like to be able to do the same for HEAD. I need to do this to help with the numerous tickets asking about library regressions. For example, I want to be able repoduce @harendra's examplehttps://gitlab.haskell.org/ghc/ghc/-/issues/19557#note_348969, but I can't because I can't build streamly. Thanks! Simon
There’s hackage head, which has some docs on the gitlab instance. Though I’m not up to date on how to use it. On Thu, Apr 29, 2021 at 4:24 AM Simon Peyton Jones via ghc-devs < ghc-devs@haskell.org> wrote:

Yes, in particular, this:
https://gitlab.haskell.org/ghc/head.hackage
Readme there has some documentation…

Thanks for pulling that up! I was doing errands away from my desktop all

As noted by others, we maintain head.hackage for precisely this reason. It's not perfect, but I use it regularly to build Hackage packages with pre-releases. I have a draft blog post (which sadly has run into technical challenges which have prevented publishing) which describes usage [1].
