Setting up Haskell
1 On CSE Machines
GHC and the build-tool cabal are already set up on CSE machines, but they
are not configured correctly and may fail to build your assignments.
In order to avoid build troubles, and to make sure everyone is using
the same set of dependencies, we have set up an appropriate version of
GHC and associated tools in the course account. To use it, type 3141
into a CSE terminal:
$ 3141 newclass starting new subshell for class COMP3141...
For the assignments, the cabal build tool is available.
To open ghci, you can run cabal repl.
2 Home machine
We recommend installing the
stack
build tool for Haskell. Once this is done, the entire compiler toolchain
can be installed just by typing stack setup. This should work on Linux,
Windows and Mac. Alternatively, the compiler
and toolchain can be installed from distribution package managers on Linux,
but these are often out of date or configured incorrectly.
Typing stack repl should open ghci and stack exec ghc can be used to
run ghc.
All assignments and exercises will come with build instructions. If you are
using this setup, follow the instructions for stack users.
