# This Makefile can be used to cross-compile pForth on a Linux host to
# an Amiga target.  GCC is used as host-compiler and VBCC as
# cross-compiler.

# makefile for pForth
# Portable Forth written in 'C'
# by Phil Burk
# For more info visit http://www.softsynth.com/pforth/
#
# See "help" target below.

# Options include: PF_SUPPORT_FP PF_NO_MALLOC PF_NO_INIT PF_DEBUG
# See "docs/pf_ref.htm" file for more info.

# We are going to use VBCC as cross compiler.  I've installed VBCC
# under /opt/m68k-amigaos.  It's configured to generate Motorola 680x0 code in
# "Amiga Hunk" object format.
