cabal install not working #58
Comments
|
I tried a different machine with Ubuntu 18.04 and a completely fresh install via https://www.haskell.org/ghcup/ that went flawlessly, with defaults on every prompt. Then when I did "cabal install mikrokosmos" I got the same error, per below. bruce@bruce-Latitude-E6410:~$ cabal install mikrokosmos
Failed to build exe:mikrokosmos from mikrokosmos-0.8.0. source/NamedLambda.hs:24:1: warning: [-Wunused-imports] source/Stlc/Block.hs:14:10: error: source/Stlc/Block.hs:55:10: error: source/Stlc/Block.hs:56:10: error: source/Stlc/Block.hs:79:32: error: bruce@bruce-Latitude-E6410:~$ |

Thank you so much for pointing this! I think that this is actually solved in the current version code (with the last three commits or so). However, this version is not yet on Hackage, and so you get the problem when cabal-installing. Installing Mikrokosmos from the repository should still work. Meanwhile, I should try to update it on Hackage. This was also raised in #57. |

YES thank you it worked per below bruce@bruce-ThinkPad-X1-Yoga-1st:

I am new to Haskell and hoping to try Mikrokosmos, but I can't get it to install. A few months ago I struggled to install Haskell, and so I started over with a "ghcup nuke" and fresh install of Haskell and cabal per https://www.haskell.org/ghcup/install/, which seemed to go fine on my Ubuntu 20 machine. But when I do "cabal install mikrokosmos" it fails, per below. Any tips? Thank you!
