Re: Help needed: Updating GHC to 8.4.3

Hey Tim,

thank you so much for helping with GHC!

I set the LD environment variable as suggested and the package build is
getting much further.  Thank you!

I’m not too concerned about the 2nd and 3rd problems, because at least
GHC 8.4.3 will likely be good enough to build all of our Haskell
packages.

We should record the other problems as bugs on address@hidden
