Re: Which stable GHC release is expected to have support for linear types?

Hi, Edvard! I renamed the local directory after cloning. If Git really cannot deal with this, then this is yet another reason for preferring darcs over Git. Unfortunately, it would be hard to reproduce this problem, since I took slightly different steps before incorporating the linear-types branch, as I did not yet know about the documentation on getting the linear- types branch at that time.

Hi Wolfgang, 

the directory name should not matter (mine is named differently for example). Renaming the base directory after cloning (instead of using git clone foo dir-name) can sometimes confuse git, if that might be the problem.

In any case, we are unable to reproduce this so if you could provide exact reproductions steps we can update the guide. Your git version may be useful as well.

Cheers, Edvard

Hi, Edvard!

I generally followed the instructions on

    https://github.com/tweag/ghc/tree/linear-types#building-from-sou rce  ,

but when running

    git checkout tweag/linear-types  ,

I got the following error message:

...

 fatal: Not a git repository: ${BASEDIR}/ghc/.git/modules/.arc- linters/arcanist-external-json-linter

I guess this is because my local directory is not named “ghc”, but “ghc- linear”. In my opinion, the repository should not assume that a local copy of it resides in a directory of a certain name. Is this a GHC issue or an issue with your linear-types branch?

All the best, Wolfgang

Hi Wolfgang, 

I've put together a small README for getting this up and running (both for using stack with pre-built Docker images, and from source). It can be found in the repository here: https://github.com/tweag/ghc/tree /lin ear-types.

Hope this will help!
