I followed the procedure here for installing GHC and cabal, and then for ghc-mod.
But, I get this error at this step
cabal update && cabal install cabal-install
Configuring cabal-install-1.24.0.2... Failed to install cabal-install-1.24.0.2 cabal: Error: some packages failed to install: cabal-install-1.24.0.2 failed during the configure step. ExitFailure 11
If you install
haskell-platform
viaapt-get
, version ofghc
is under7.10.3
until yakkety (Ubuntu 16.10).This is problematic because
cabal-1.24
requiresghc >= 8.0.1
.To solve this
ghc
from its code,stack
andghc-mod
forstack
.P.S. if you are emacsen, I recommand you to use
intero
(site) instead ofghc-mod
.
