Build does not complete - floskell, ormolu, hlint failures

I got errors when building just now, too.

In Windows 10, I cloned this repo, then did stack install.

Any ideas about what's going wrong here? I'm not an experienced Haskell developer.

It looks like the GHC version it's using is 8.8.2.

$ stack ghc -- --version
Stack has not been tested with GHC versions above 8.6, and using 8.8.2, this may fail
Stack has not been tested with Cabal versions above 2.4, but version 3.0.1.0 was found, this may fail
The Glorious Glasgow Haskell Compilation System, version 8.8.2

When I cloned, I did not add the submodule flag.

That is I did this: git clone https://github.com/haskell/haskell-ide-engine

Where the README says to do this: git clone https://github.com/haskell/haskell-ide-engine --recurse-submodules

Could this be part of the problem?

[chexxor]

It looks like the current version of the .gitmodules file is empty, so maybe submodules are no longer used in the project?

Submodules are, indeed, no longer needed.

I got the build to work using these commands:

# Remove the git clone directory which had the failing build.
$ rm -rf hie

# Clone it again into C:\hie
$ git clone https://github.com/haskell/haskell-ide-engine --recurse-submodules hie 

$ cd hie
# Make another mistake because the build instructions say it uses shake, so I try to reverse the command.
$ stack install shake
$ stack purge # I also deleted the exe from my local bin directory
$ rm -rf .stack-work/
$ stack install

# Maybe I cancelled that previous one? Because I ran this one 
$ stack ./install.hs hie

After that last command, I got a success.

No longer an issue! User error!

I'll submit a PR to clarify the README.

Glad to see the issue is resolved.

The key is to use stack install.hs hie, it runs the install script that uses the latest ghc version that works with windows (ghc-8.6.5) to installing hie. At the core it does a stack install --stack-yaml stack-8.6.5.yaml (among other necessary things, so i would suggest use it by default to install hie)

stack install uses the default stack.yaml config file, that makes it use ghc-8.8.2 and i am afraid it cant be used in windows due a compiler bug.
