# Makefile for Firebee BaS
|
|
#
|
|
# This Makefile is meant for cross compiling the BaS with Vincent Riviere's cross compilers.
|
|
# If you want to compile native on an Atari (you will need at least GCC 4.6.3), set
|
|
# TCPREFIX to be empty.
|
|
# If you want to compile with the m68k-elf- toolchain, set TCPREFIX accordingly. Requires an extra
|
|
# installation, but allows source level debugging over BDM with a recent gdb (tested with 7.5),
|
|
# the m68k BDM tools from sourceforge (http://bdm.sourceforge.net) and a BDM pod (TBLCF and P&E tested).
|
|
|
|
# can be either "Y" or "N" (without quotes). "Y" for using the m68k-elf-, "N" for using the m68k-atari-mint
|
|
# toolchain
