L.S., I am trying to get wxHaskell compiled with GHC 8.4.0.20180224 and cabal-install 2.1.0.0; compilation fails with the message: wxcore-0.93.0.0-1L9rVktyK3zIYrrLxBiCr9 failed during the final install step. The exception was: dieVerbatim: user error (cabal: Couldn't parse the output of 'setup register --gen-pkg-config':NoParse "license" 5 ) I am using Windows 8.1. Can anybody tell me what to do about this? Regards, Henk-Jan van Tuyl -- Message from Stanford University: Folding@home What if you could share your unused computer power to help find a cure?
