stack repl stack:lib bytecode compiler can't foreign

[philderbeast]

Steps to reproduce

On this very repo:

> stack repl stack:lib
Configuring GHCi with the following packages: stack
GHCi, version 8.10.4: https://www.haskell.org/ghc/  :? for help
Loaded GHCi configuration from /Users/pdejoux/.ghci
[  1 of 110] Compiling Network.HTTP.StackClient
[  2 of 110] Compiling Path.Extended
...
[ 80 of 110] Compiling System.Process.Pager
[ 81 of 110] Compiling System.Terminal
Error: bytecode compiler can't handle some foreign calling conventions
  Workaround: use -fobject-code, or compile this module to .o separately.

<no location info>: error:
    Could not load module ‘Stack.Build’
    It is a member of the hidden package ‘stack-2.7.6’.
    You can run ‘:set -package stack’ to expose it.
    (Note: this unloads all the modules in the current scope.)

I tried stack build stack:lib that worked but going back to the above command still fails the same way.

Expected

I'd expect to be able to load stack's lib into the REPL.

I hope a new binary version of Stack will be available soon on all major operating systems (see #5733). I am using the version of Stack built from the current master branch:

> stack install # In the root of the Stack repository

If you are on macOS, you would want to install that version of Stack with:

$ stack --stack-yaml=stack-macos.yaml install

Using that version of Stack yields for me (at least, on Windows 11):

> stack repl stack:lib
If building Stack on macOS, you are advised to use stack-macos.yaml as the
project-level configuration file, and command:

stack --stack-yaml stack-macos.yaml build

See that configuration file for further information.

Ok, 110 modules loaded.

@philderbeast, does using a current version of Stack on macOS also solve the problem you identify?

Using that version of Stack yields for me (at least, on Windows 11):

I don't think you can reproduce that on windows.

This is very common and not really a stack bug.

See:

• https://gitlab.haskell.org/ghc/ghc/-/issues/7388
• https://gitlab.haskell.org/ghc/ghc/-/merge_requests/6904

So it seems the first version that doesn't have this problem is GHC 9.2.4. On mac you should not use that version though, but 9.2.5.

@hasufell thanks, didn't know what was it, but upgrading my stack resolver solved it.
