Issue installing hlint on windows-CodePudding

I'm trying to install hlint on Windows using: cabal install hlint, and I get the following error:

   Preprocessing executable 'hlint' for hlint-1.8.50..

cabal.exe: Failed to build hlint-1.8.50. See the build log above for details.

Glorious Glasgow Haskell Compilation System, version 9.2.1, hlint-1.8.50

CodePudding user response：

As per the comment of Neil Mitchell "no released version of HLint can be used with GHC 9.2.1 (since some of its dependencies aren't yet ready)" it is not possible to run HLint with GHC 9.2.1, which is installed by default with Chocolatey and Haskell Platform for Windows.

However, I found a workaround. I installed GHCup for Windows:

Set-ExecutionPolicy Bypass -Scope Process -Force;[System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072;Invoke-Command -ScriptBlock ([ScriptBlock]::Create((Invoke-WebRequest https://www.haskell.org/ghcup/sh/bootstrap-haskell.ps1 -UseBasicParsing))) -ArgumentList $true

GHCup installs with cabal and ghc 8.10.7, which is perfectly compatible with HLint. In order to install HLint I ran:

cabal update
cabal install hlint

After that added location of the newly created hlint binary to PATH. And Voilà: Everything worked like a charm!
