please add a resolver for ghc-9.2.3

stack setup --resolver ghc-9.2.3
Stack has not been tested with GHC versions above 9.0, and using 9.2.3, this may fail
No setup information found for ghc-9.2.3 on your platform.
This probably means a GHC bindist has not yet been added for OS key 'macosx'.
Supported versions: ghc-7.8.4, ghc-7.10.1, ghc-7.10.2, ghc-7.10.3, ghc-8.0.1, ghc-8.0.2, ghc-8.2.1, ghc-8.2.2, ghc-8.4.1, ghc-8.4.2, ghc-8.4.3, ghc-8.4.4, ghc-8.6.1, ghc-8.6.2, ghc-8.6.3, ghc-8.6.4, ghc-8.6.5, ghc-8.8.1, ghc-8.8.2, ghc-8.8.3, ghc-8.8.4, ghc-8.10.1, ghc-8.10.2, ghc-8.10.3, ghc-8.10.4, ghc-8.10.5, ghc-8.10.6, ghc-8.10.7, ghc-9.0.1, ghc-9.0.2, ghc-9.2.1, ghc-9.2.2

stack, by default, looks at https://github.com/commercialhaskell/stackage-content/blob/master/stack/stack-setup-2.yaml for this information. An issue has been opened in that respository: commercialhaskell/stackage-content#103

If you cannot wait, I think you can do something like this:

1. Create your own local stack setup YAML file. I am on Windows 64, so I created something like this, named my-stack-setup.yaml:

ghc:
  windows64:
    9.2.3:
      url: "http://downloads.haskell.org/~ghc/9.2.3/ghc-9.2.3-x86_64-unknown-mingw32.tar.xz"
      content-length: 504613996
      sha1: 0c3ea029fb9b9c6a0ceeee453d76b2ec474eb25c
      sha256: 0543d80c1ef453a5f82d0a2bc436f93d2feb3d5855114c8a78a12c561c9bc8df

sevenzexe-info:
  url: "https://github.com/fpco/minghc/blob/master/bin/7z.exe?raw=true"
  content-length: 73728
  sha1: 187dff8a3327da87050f678579816e5bae40c632

sevenzdll-info:
  url: "https://github.com/fpco/minghc/blob/master/bin/7z.dll?raw=true"
  content-length: 447488
  sha1: 168a288d4456f0473f66e86a2d6fec4eb6f4b993

I took the URL from this site: https://www.haskell.org/ghc/download_ghc_9_2_3.html#binaries. I downloaded the file to see what size it was in bytes (content-length) and (in PowerShell) used the tool (Get-FileHash ghc-9.2.3-x86_64-unknown-mingw32.tar.xz -Algorithm SHA256).Hash.ToLower() to get the file's hash (sha256) - and similarly for sha1.

I took the sevenzexe-info and sevenzdll-info verbatim from https://github.com/commercialhaskell/stackage-content/blob/master/stack/stack-setup-2.yaml. stack needs these, or it will not unzip the downloaded GHC - even if 7-Zip is already in place.

2. Build a simple test program that has resolver: ghc-9.2.3 in its stack.yaml file, with stack --setup-info-yaml=my-stack-setup.yaml build`. This will set off the download and installation of GHC 9.2.3.

3. Once GHC 9.2.3 is installed where stack expects to find it, there is no longer any need for --setup-info-yaml=my-stack-setup.yaml on the command line.

@mpilgrem this is awesome information, thanks so much mike! ok, so i was able to use this to get some local testing going and that enables me to make progress while we wait on commercialhaskell/stackage-content#103 and i get CI builds going at this version. i'll close this ticket. thanks!!

oh, just for completeness, i wrote stack-setup-2-ghc-9.2.3.yaml with contents

ghc:
  macosx:
    9.2.3:
      url: http://downloads.haskell.org/~ghc/9.2.3/ghc-9.2.3-x86_64-apple-darwin.tar.bz2
      content-length: 279717482
      sha1: 213391478ba6bf7cc81c89a2959360e58b811c54
      sha256: f6803356d2ddb4ad3d68372bf23ef61d2a9bc670c099086319f2bee96c457a0a

and used it to install ghc-9.2.3 via,

stack --setup-info-yaml stack-setup-2-ghc-9.2.3.yaml --resolver ghc-9.2.3 setup

nightly-2022-06-10 has GHC 9.2.3.
