`os-string` has been split from `filepath` in filepath 1.5.0.0. If you search for "flag(os-string)" in unix' cabal file here: https://hackage.haskell.org/package/unix-2.8.5.1/unix.cabal you'll see that the package has been set up to use `os-string` if `filepath >= 1.5.0.0`, and to not depend on `os-string` otherwise. For filepath < 1.5.0.0, the modules in question are in the `filepath` package. You can get them by manually depending on `filepath` too. If you want the post-`os-string` split `filepath`, simply add a lower bound on the version of `filepath` in your thing.cabal file: `filepath >= 1.5.0.0`. As you can see, the diagnostic you got shows that you were indeed using an older `filepath` version. - Tom On 30/05/2024 22:22, Andrew Lelechenko wrote: > Normally you do not need to set `constraints: unix +os-string, directory +os-string`.
