cabal: Could not resolve dependencies
L.S., I am trying to compile wxHaskell with GHC 8.8.0.20190721 and I get the following messages from cabal-install:
cabal new-build all --disable-documentation Resolving dependencies... cabal: Could not resolve dependencies: [__0] trying: samplesContrib-0.93.0.0 (user goal) [__1] trying: base-4.13.0.0/installed-4.1...

(constraint from maximum version of Cabal used by Setup.hs requires <2.6 [...]
What does this mean, how do I solve it? (There is a Setup.hs in package wxcore, but does it have its own Cabal file?)
cabal --version cabal-install version 2.4.1.0 compiled using version 2.4.1.0 of the Cabal library

Is there a reason you're using GHC 8.8.1? This means that wxcore uses a custom setup, and that custom setup requires Cabal <2.6. But you can't use Cabal 2.4 because that requires base <4.13 Cheers, Vanessa McHale On 8/6/19 7:11 PM, Henk-Jan van Tuyl wrote:
