According to stack.yaml  we use the lts-8.24 resolver. According to https://www.stackage.org/lts-8.24 it contains ghc-8.0.2 Also after a build, searching .stack/ folder for "ghc-" returns: $ find .stack-work -iname "*ghc-*" .stack-work/install/x86_64-linux-nopie/lts-8.24/8.0.2/lib/x86_64-linux-ghc-8.0.2 .stack-work/install/x86_64-linux-nopie/lts-8.21/8.0.2/lib/x86_64-linux-ghc-8.0.2 # ← this is from when we where on lts-8.21 I have only a superficial understanding of this but it seems safe to say that we use ghc-8.0.2 Cheers, -- Victor/tuxayo  https://git.snowdrift.coop/sd/snowdrift/blob/master/stack.yaml#L4 _______________________________________________ Dev mailing list Dev@lists.snowdrift.coop https://lists.snowdrift.coop/mailman/listinfo/dev
