# NOTE: This assumes that a working `ghc` is on $PATH; this may not
# necessarily be the same GHC used by `cabal` for building `happy`.
#
# Again, if HC has been set in the environment (e.g. by the CI), we keep this setting.
# [2021-07-14, PR #196](https://github.com/haskell/happy/pull/196)

HC ?= ghc
HC_OPTS=-package array -Wall -Werror -XHaskell98

# NOTE: `cabal test` will take care to build the local `happy`
# executable and place it into $PATH for us to pick up.
# (This is ensured by setting build-tool-depends.)
#
# If it doesn't look like the alex binary in $PATH comes from the
# build tree, then we'll fall back to pointing to
# ../dist/build/alex/alex to support running tests via "runghc
# Setup.hs test".
#
# If HAPPY has been set outside, e.g. in the environment, we trust this setting.
# This way, we can pass in the correct Happy executable from a CI environment
# without danger of it being "fixed" by the logic below.
