# Toplevel Makefile for GreenCard
# 
# Typical usage:
#
# Linux:   sudo make install
#          sudo make prefix=$HOME install
# Windows: make prefix=c:/greencard install
#

# === User serviceable parts:

# Path to Haskell compiler
HC=ghc

# Path to C compiler
CC      = gcc

# When building for GHC, we can build for profiling, etc.
WAYS=p

# You only need to adjust these if you
# should need to change the parser
HAPPY = happy

# Set to 1 if you're compiling for Win32
PURE_WIN32=0
# [ The effect of this option is to control whether
#   ';' (PURE_WIN32=1) or ':' (PURE_WIN32=0) is used
#   as path separator when GreenCard processes the -i
#   option.
# ]

# installation directories - override when invoking make
prefix = /usr/local
bindir = $(prefix)/bin
libdir = $(prefix)/lib/greencard-3.01

# === End of user-serviceable parts

#  Legal values: GHC, NHC or HUGS
