# Makefile configuration for Hatari.
#
# Use of '?=' for assignment allows overriding the given value with
# an environment variable, like this:
# 	HOSTCC=my-hostcc make
# or:
#	export HOSTCC=my-hostcc
#	make
#
# Following variables can be overridden like that:
#   CPPFLAGS, LDFLAGS, LIBS, HOSTCC, DATADIR, CONFDIR, BINDIR, MANDIR, DOCDIR
#
# GNU make itself supports overriding CC like this:
#	make CC=my-cc

# Set the C compiler (e.g. gcc)
CC = gcc

# To run, use something like (disable sound as it can break things):

# For more info, see (for now, works properly only for x86 gcc):
