Description
Describe the bug
Can't compile a haskell package using GHC2024 as default-language.
- Tested on system
aarch64-linux(don't think it's relevant as cabal build works fine). - GHC 9.10.2 (which builds sucessfully)
- Haskell.nix commit
f7bea9839be61422bf73b07c64a7eacbb9568f7eused.
Steps To Reproduce
git clone https://github.com/janvogt/haskell-nix-doesnt-support-GHC2024
cd haskell-nix-doesnt-support-GHC2024
nix develop
# cabal works:
cabal run hello:exe:hello
# haskell.nix fails:
nix run .#hello:exe:helloExpected behavior
Expected both cabal run and nix run to work and output Hello, GHC2024
Actual behaviour
cabal run works and nix run fails with:
nix run .#hello:exe:hello
error: builder for '/nix/store/6pm6s20b08ca011n7awb8dniy5qik1mw-hello-exe-hello-1.0.0.2.drv' failed with exit code 1;
