Cabal install HaskellForMaths fails

I'm trying to install Quipper using this readme. Cabal-install fails on installing Lattices:

cabal: Error: some packages failed to install:
HaskellForMaths-0.4.8 failed during the building phase. The exception was:
ExitFailure 1
Lattices-0.0.2 depends on HaskellForMaths-0.4.8 which failed to install.

I tried to install HaskellForMaths, but it fails with same error.

Solution

  • The problem seems to be that you're trying to build HaskellForMaths with a version of the base package that does not export *> and <*, these were probably added in base version 4.8.0.0 which shipped with GHC 7.10.1.

    I would suggest that you upgrade to the latest GHC (7.10.2).
