Describe the bug

When trying to use build-tool-depends: markdown-unlit:markdown-unlit

I get

plutarch-docs:markdown-unlit:exe.markdown-unlit-0.5.1/installed-4CgIbMeCiwSElzbwyyhikO
(does not contain executable 'markdown-unlit', which is required by my-library *test)

Which is wrong.

Build system: x86_64-linux
GHC version: 924
Haskell.nix version: 5eccdb523

Steps To Reproduce

add the following to your cabal file:

  ghc-options: -pgmL markdown-unlit

  build-depends:
    , base
    , markdown-unlit

  build-tool-depends: markdown-unlit:markdown-unlit

Expected behavior

cabal manages to resolve the executable

Additional context

This is probably related to another issue I opened, #1662. Also related: https://github.com/haskell/cabal/issues/8481 https://github.com/input-output-hk/cardano-node/issues/4455

839

This doesn't happen in the testcases in haskell.nix (like test/shell-for) because the dependencies are not resolved via haskell.nix but locally via cabal.

This is a huge issue causing all sorts of ugly hacks in practice.

There are some other issues that might have the same underlying cause, here: https://gist.github.com/ScottFreeCode/ef9f254e2dd91544bba4a068852fc81f

input-output-hk / haskell.nix

Executables are not used in `build-tool-depends` if the library is obtained via `haskell.nix` #1770
