cabal-helper-wrapper "print-build-platform" (exit 1): failed.

When i open a .hs file in vscode, an error occurred following:

Got error while processing diagnostics: readCreateProcess: /Users/foo/dev/study/haskell-ide-engine/.stack-work/install/x86_64-osx/lts-13.0/8.6.3/bin/cabal-helper-wrapper "print-build-platform" (exit 1): failed

Does /Users/foo/dev/study/haskell-ide-engine/.stack-work/install/x86_64-osx/lts-13.0/8.6.3/bin/cabal-helper-wrapper exist?

After installing hie, you have to leave the directory intact that it was installed from.

[ghost]

Yep, That file exists.

$ ls -l /Users/foo/dev/study/haskell-ide-engine/.stack-work/install/x86_64-osx/lts-13.0/8.6.3/bin/cabal-helper-wrapper
.rwxr-xr-x      1 6.8Mi foo staff 2018-12-29 18:53 /Users/foo/dev/study/haskell-ide-engine/.stack-work/install/x86_64-osx/lts-13.0/8.6.3/bin/cabal-helper-wrapper

[alanz]

And what happens if you run

/Users/foo/dev/study/haskell-ide-engine/.stack-work/install/x86_64-osx/lts-13.0/8.6.3/bin/cabal-helper-wrapper print-build-platform

[ghost]

The result:

$ /Users/foo/dev/study/haskell-ide-engine/.stack-work/install/x86_64-osx/lts-13.0/8.6.3/bin/cabal-helper-wrapper print-build-platform
cabal-helper-wrapper: dieVerbatim: user error (cabal-helper-wrapper: The program 'ghc' version >=7.0.1 is required but it
could not be found.
)

Hmm, do i need to expose ghc command on my bash environment? I am using stack ghc instead of ghc:

$ ghc --version
zsh: command not found: ghc

$ stack ghc -- --version
The Glorious Glasgow Haskell Compilation System, version 8.6.3

[alanz]

It looks like the wrapper is also expecting a system ghc to be installed.

What I do is just symlink the stack one in to a location on the path somewhere, but in the meantime this is a bug, I will look into it.

[alanz]

This line is the problem.

https://github.com/alanz/cabal-helper/blob/cabal-new-legacy/src/CabalHelper/Compiletime/Wrapper.hs#L162

[ghost]

Oh, you are right. Thanks. I appended a path for ghc into my .zshrc file following. And the error was gone. Is this a right way to fix this error, especially the path for ghc ?:

export PATH=~/.stack/programs/x86_64-osx/ghc-8.6.3/bin:$PATH

Or

export PATH=$(stack path | grep ^bin-path):$PATH

[alanz]

you can also use

export PATH=$(stack path --compiler-exe):$PATH

[ghost]

I assume --compiler-exe should be --compiler-bin... :)

$ stack path --compiler-exe
/Users/foo/.stack/programs/x86_64-osx/ghc-8.6.3/bin/ghc

$ stack path --compiler-bin
/Users/foo/.stack/programs/x86_64-osx/ghc-8.6.3/bin

[FledgeXu]

Hey Guys,I have the same problem.

  ls -l /Users/fledge/Develpment/haskell-ide-engine/.stack-work/install/x86_64-osx/lts-13.5/8.6.3/bin/cabal-helper-wrapper

-rwxr-xr-x  1 fledge  staff  7089880 Feb 21 20:41 /Users/fledge/Develpment/haskell-ide-engine/.stack-work/install/x86_64-osx/lts-13.5/8.6.3/bin/cabal-helper-wrapper

When I run the cabal-helper-wapper, It shows:

cabal-helper-wrapper: dieVerbatim: user error (cabal-helper-wrapper: The program 'ghc' version >=7.0.1 is required but it
could not be found.
)

what should I do?

Should I install ghc above 7.0 by stack?

[ghost]

@FledgeXu You should add ghc command to PATH environment variable of your shell.

[FledgeXu]

@jinbeomhong It works! Thank you for your help.

[krikchaip]

I assume --compiler-exe should be --compiler-bin... :)

$ stack path --compiler-exe
/Users/foo/.stack/programs/x86_64-osx/ghc-8.6.3/bin/ghc

$ stack path --compiler-bin
/Users/foo/.stack/programs/x86_64-osx/ghc-8.6.3/bin

Hi there,
I already did this. but the error still occurs 😕

$ haskell-ide-engine/.stack-work/install/x86_64-osx/lts-12.26/8.4.4/bin/cabal-helper-wrapper print-build-platform

[KillyMXI]

I got this on Windows 10.
I would love to not depend on workarounds for this issue.

[luochen1990]

Following is my workaround (as a summarize of @alanz and @jinbeomhong 's above comment):

add export PATH="$(stack path --compiler-bin):$PATH" to rc file, so that the command ghc works, and this issue gone.

Hi... I got the following error when trying to run vscode-hie-server extension on my WSL.

Got error while processing diagnostics: readCreateProcess: /nix/store/1i3fyx4wywvkzz1fcji6zysshvxvx5ja-cabal-helper-0.9.0.0/bin/cabal-helper-wrapper "--with-ghc=ghc" "--with-ghc-pkg=ghc-pkg" "--with-cabal=cabal" "v1-style" "/home/rizary/Haskell/alltuts/fp-course" "/home/rizary/Haskell/alltuts/fp-course/dist" "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 all-hies and hvr:ppa for my cabal and ghc/ghcjs binary.

One thing that I noticed here is that cabal-helper put this "v1-style" "/home/rizary/Haskell/alltuts/fp-course" "/home/rizary/Haskell/alltuts/fp-course/dist" argument automatically whereas I'm using v2-style and the dist folder is not existed (dist-newstyle is).

So I try to run it manually and change it into:

"--with-ghc=ghc" "--with-ghc-pkg=ghc-pkg" "--with-cabal=cabal" "v2-style" "/home/rizary/Haskell/alltuts/fp-course" "/home/rizary/Haskell/alltuts/fp-course/dist-newstyle" "package-db-st
ack" "flags" "compiler-version" "ghc-merged-pkg-options" "config-flags" "non-default-config-flags" "ghc-src-options" "ghc-pkg-options" "ghc-lang-op
tions" "ghc-options" "source-dirs" "entrypoints" "needs-build-output"

and get the following output:

  course-0.1.4-in place
  course-0.1.4-in place-tasty

Is this output already what is intended by cabal-helper-wrapper? Or how can I have plan.json?

Does this issue still relevant to this thread?

[infinisil]

I think as of now HIE doesn't work well with the new-style commands (haskell/haskell-ide-engine#962 is related). For my development I'm therefore still using the old-style commands.

[nwaywood]

I am getting this same error message:

Got error while processing diagnostics: readCreateProcess: /Users/nick/code/src/github.com/haskell/haskell-ide-engine/.stack-work/install/x86_64-osx/7dfa7340ecd7919dc6ad0bc2cca5d855561f4efbe97f9adff94af88edbcb34ed/8.6.5/bin/cabal-helper-wrapper "--with-ghc=ghc" "--with-ghc-pkg=ghc-pkg" "--with-cabal=cabal" "v1-style" "/Users/nick/code/src/github.com/nwaywood/fp-course" "/Users/nick/code/src/github.com/nwaywood/fp-course/dist" "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

But the solutions above do not work for me. When I run:

/Users/nick/code/src/github.com/haskell/haskell-ide-engine/.stack-work/install/x86_64-osx/7dfa7340ecd7919dc6ad0bc2cca5d855561f4efbe97f9adff94af88edbcb34ed/8.6.5/bin/cabal-helper-wrapper print-build-platform

The output is x86_64-osx

But when I run the full command from the error message I get:

cabal-helper-wrapper: /Users/nick/code/src/github.com/nwaywood/fp-course/dist-newstyle/build/x86_64-osx/ghc-8.6.5/course-0.1.4/setup-config: openFile: does not exist (No such file or directory)

The dist-newstyle directory seems to be auto created from this plugin so I'm not sure how to proceed from here. Any debugging hints or solutions would be appreciated. Thanks

[jneira]

hie not longer uses cabal-helper-wrapper and it is able to start using stack if there is no ghc on path so i think this should be fixed with latest versions of hie and the extension: @srcdes @FledgeXu @krikchaip @KillyMXI @Rizary @luochen1990 feel free to reopen if it is not the case
