Cabal build does not work with 1.6.0 about orbstack HOT 5 CLOSED

Fixed for the next version. Thanks for the reproducer!

Download old versions from: https://docs.orbstack.dev/downgrade

Try at your own risk:

If OrbStack panics on startup after a downgrade saying downgrading is unsupported, delete the vmstate.json file in your .orbstack directory. For me on MacOS, that is $HOME/.orbstack/vmstate.json.

Can you share steps or a sample project to reproduce, or a screenshot of the exact error message?

Steps:

0. Get cabal, on Nix its:

nix-shell -p cabal-install

1. Create a cabal project from the vm, but with your cwd on mac side. I used my mac $HOME.

cabal init foo

2. Run cabal build.

cabal build

This should be the error:

Error: cabal: There is no <pkgname>.cabal package file or cabal.project file.
To build packages locally you need at minimum a <pkgname>.cabal file. You can
use 'cabal init' to create one.

For non-trivial projects you will also want a cabal.project file in the root
directory of your project. This file lists the packages in your project and
all other build configuration. See the Cabal user guide for full details.

But for some reason cabal v1-build works. I should add, the above cabal error can be misleading, and not reflect the actual cause.
