haddock build fails #418

Closed damiencourousse closed 5 years ago

damiencourousse commented 5 years ago

Using stackage's lts-12.4, which includes version 1.20.3.
Building Haddock documentation locally with stack, I get this:

It looks like the problem is in different settings in Stack - it hyperlinks sources by default, I get the same result with new cabal commands using the latest at this moment comit e0f2aa86d68b993f0a81633af467dc550b3e7270 -

mpickering commented 5 years ago

Seems like a bug in haddock to me?

qrilka commented 5 years ago

Looks like it was resolved in GHC 8.6.1

qrilka commented 5 years ago

stack haddock fine for me with lts-13.0

damiencourousse commented 5 years ago

yes, it's also fine for me with lts-13.0 thanks!
