`writeHieFiles = true` breaks on `mtl-compat`

[dhess]

We've been using writeHieFiles = true since it was introduced, but now that we're pulling in Protolude, which pulls in mtl-compat-0.2.2, it's breaking on mtl-compat. See https://gist.github.com/dhess/861e91625bff4d6401494c40cffe6a96

Any idea why it might be breaking on that package? Any way to disable wriiteHieFiles just for that package?

It's a per-component option, no? So you should just be able to turn it off on the component where it doesn't work.

My guess as to why it breaks is that mtl-compat defines no Haskell entities of its own. Perhaps in that case you don't get a HIE file for the module (might have to ask the GHC maintainers). But it looks like something is trying to find a HIE file unconditionally, not sure what.

Hah, you're right! This did the trick:

packages.mtl-compat.writeHieFiles = false;

Once again, I'd just like to express what a joy it is to use this project.

Shall I keep this issue open as a way to track that? Or do you prefer that I close it now that the immediate problem is resolved?

Yeah, it's still a bug, although I guess not super-high priority.
