`stack build` command failed with the message can't load framework: Cocoa (not found) about hid-examples

Hi Antonel, thanks for opening this issue! I've updated the stack.yaml file. Could you please check if the current version works for you?

Hi @bravit

It is fine now. stack build and stack test commands run without any issue.
The only thing that could improve (at least) my experience of working with haskell, would be to use another stackage, in order to have support for the vs code haskell language server.

I know that IDEs is totally another story, but, at least for me, having a decent support in the IDE (vs code) would be a tremendous good addition to the development toolbox.

In one of my learning projects I switched from LTS Haskell 17.4 (ghc-8.10.4) to LTS Haskell 16.31 (ghc-8.8.4) just to have this support.

You can see here the ghc versions currently supported by the VS code haskell extension.

Is it possible to have the stackage LTS Haskell 16.31 (ghc-8.8.4) instead of the current one (even if in a different branch)? Just if you consider this worth the effort.

Thank you.

Note:

• This is the exception I've got with the VS code Haskell extension using the GHC version brought by the current stackage.

Unfortunately, there is a problem. The bug you've encountered while using Big Sur is the bug in GHC. It was fixed in ghc-9.0.1 and then backported to ghc-8.8.5 and ghc-8.10.3. You could try resolver: lts-17.2 in stack.yaml and see if it works for your setup.

I will try your suggestion.
Definitely the initial reported issue has been fixed. So, this issue can be closed.

Thanks again for your help.

Your suggestion works, and the Haskell language server has been successfully downloaded and install by vs code.

This is great. Thanks.

There is nothing stopping me now to start learning Haskell, considering that I also have an amazing companion: Haskell in depth book. ;)
