# openMSX Build System
# ====================
#
# This is the home made build system for openMSX, which replaced the
# autoconf/automake combo.
#
# Used a lot of ideas from Peter Miller's excellent paper
# "Recursive Make Considered Harmful".
# http://miller.emu.id.au/pmiller/books/rmch/

# TODO:
# - Move calculation of CFLAGS and LDFLAGS to components2defs.py?


# Python Interpreter
# ==================

# We need Python from the 2.x series, version 2.5 or higher.
# Usually this executable is available as just "python", but on some systems
# you might have to be more specific, for example "python2" or "python2.6".
# Or if the Python interpreter is not in the search path, you can specify its
# full path.
ifeq ($(PYTHON),)
PYTHON:=$(shell build/python-search.sh)
ifeq ($(PYTHON),)
$(error No suitable Python interpreter found. Please install Python version 2.x where x >= 5. If your Python interpreter is installed in a non-standard location, please set the environment variable PYTHON to the full path of the interpreter binary.)
endif
endif

# Delete on Error
# ===============

# Delete output if rule fails.
# This is a flag that applies to all rules.

# Logical Targets
# ===============

# Settings
# ========
#
# There are platform specific settings and flavour specific settings.
#   platform: architecture, OS
#   flavour:  optimisation levels, debugging, profiling

# Function to check a variable has been defined and has a non-empty value.
# Usage: $(call DEFCHECK,VARIABLE_NAME)

# and by this Makefile.
