build-extn.py runtime error: Could not find module ‘Kind’

[hellandhansen]

Hi!

It's possible this is obvious to the experienced, but I've gone back and forth and can't seem to resolve this issue, even when modifying the cabal file to expose Kind.

Here's the error trace.

Insights would be much appreciated. I've read through every haskell-from-python site out there...

Kind regards

I'll be happy to take a look when I can, likely in the next few days.

In the meantime, could I ask you to provide the output of ghc --version?

[hellandhansen]

Hi! Good to hear from you. It's

The Glorious Glasgow Haskell Compilation System, version 8.10.1

[tbarnetlamb]

Ok. I suspect that that's the issue; the most recent version I tested against was 8.8. hyphen accesses some GHC internals and they do tend to move around from major release to major release. I have to make occasional commits like https://github.com/tbarnetlamb/hyphen/commit/69bd64c0b872fcd418fa67155910e951ce32afdd to keep up! I will try to update the code for 8.10 (hopefully within days not weeks), but in the meantime, you might consider downgrading to 8.8 and seeing if that solves your problem.

[tbarnetlamb]

I looked into it some more and I realized that 8.10 is pretty bleeding edge. It's not yet supported by haskell stack (which is my go-to way of installing new haskell versions). How important is it to you to have access to that particular version? I guess I would prefer to wait until 8.10 is a little more widely supported (by stack at least) before I add support in hyphen, but if it's really important to you I can try to support it a bit early. (I might ask you how you installed ghc in that case, so that I can use the same installer to minimize the chance that it works differently for me that for you!)

Hi!

Thanks for being willing to go the second mile with this.

Having the bleeding edge doesn’t really matter to me. It’s something that got installed by default. I’ll try and find out how to use an earlier version.

If this is all just a version issue then nobody’s happier than me!

I’ll get back to you once I’ve downgraded.

Kind regards.

That was indeed the issue. Using 8.6, no problems.s

Hyphen rocks, heads and heels above the other implementations I've seen.

Keep up the good work ;-)
