Haskell-ide-engine: readCreateProcess error when using cabal v2-build

[razvan-flavius-panda]

Does HIE work with cabal v2-build?

For me it is throwing the following error:

Got error while processing diagnostics: readCreateProcess: /nix/store/jq8x50rkl3cm7cqkj1zsk6kfbb692iwv-cabal-helper-0.9.0.0/bin/cabal-helper-wrapper "--with-ghc=ghc" "--with-ghc-pkg=ghc-pkg" "--with-cabal=cabal" "v1-style" "/home/neo/Projects/haskell-editor-setup" "/home/neo/Projects/haskell-editor-setup/dist-newstyle/build/x86_64-linux/ghc-8.6.5/haskell-editor-setup-0.1.0.0" "package-db-stack" "flags" "compiler-version" "ghc-merged-pkg-options" "config-flags" "non-default-config-flags" "ghc-src-options" "ghc-pkg-options" "ghc-lang-options" "ghc-options" "source-dirs" "entrypoints" "needs-build-output" (exit 1): failed

I am using HIE installed via https://github.com/Infinisil/all-hies on NixOS.

[neo@nixos:~/Projects/haskell-editor-setup]$ hie --version
Version 0.12.0.0 x86_64 ghc-8.6.5

Running HIE in terminal seems to work fine:

Does exists the cabal-helper-wrapper executable in the path mentioned in the error? if it does, running the executable directly adding the --verbose option could give us more hints.

[razvan-flavius-panda]

The Atom HIE extension is the one making that call. How could I tell it to add --verbose? I can test with VSCode also (it will probably throw the same error).

[jneira]

The command should be executed in a shell. For example if i run the command in windows (it finish succesfully in my case):

@jneira Also, HIE running this command with "v1-style" seems wrong since I built the project using cabal v2.

[razvan-flavius-panda]

In VSCode I am getting this error:

readCreateProcess: cabal "configure" "--with-ghc=ghc" "--flags" "" (exit 1): failed

[razvan-flavius-panda]

Ignore the above error, that was without doing cabal v2-build before opening VSCode.

This is the error after doing the v2 build:

Hi, i've got the same error in a cabal project with an executable and i've remembered there is a previous issue about: https://github.com/haskell/haskell-ide-engine/issues/1015 (sorry for not link it early)

In that issue:

• there is a workaround,
• it states that hie only support libraries with cabal v2-build
• the definitive solution will come when this pr arrives

[razvan-flavius-panda]

@jneira Thank you! You're a hero. At least there is a workaround which if I understand correctly would only need to be done once and then later HIE builds would work fine.

I am still confused as to why the command references cabal v1 though.

Oh, and your link to the PR is not pointing at any PR. Could you update it please?

[jneira]

You are welcome, link updated!

[Infinisil]

Fyi, all-hies now has support to build the hie-bios PR, see https://github.com/infinisil/all-hies#hie-bios-versions (not cached though)

[razvan-flavius-panda]

@Infinisil I tried to use it and got this: https://github.com/Infinisil/all-hies/issues/27

[fendor]

PR #1126 has landed bringing support for Cabal 3.0.0.0 and nix-style builds!
