# 	Manual makefile to go with Eclipse
#	NOTE: enviornment variables must be set to find linker & compiler.
#	NOTE: runs with GNU Make. Might also run with Microsoft nmake with tweaks.
#
# This Makefile will compile any .c file in the current directory and link the
# objects into a .hex file to load into the robot.
#
# Rename this file "makefile" and put in your C source code folder.
# 
# The OBJFILES variable is filled with .o targets using the wildcard 
# command and patsubst. The $(wildcard *.c) will retrieve any .c 
# file in the current directory and store it in a variable. The patsubstr 
# functions is used to convert a file from one format to another. In 
# this case each .c file is converted into a .o extension and then 
# stored into OBJFILES. This variable is then used to compile each .c file.
# The rule %.o: %.c rebuilds any .o file if the cooresponding .c file has changed.
# In the compile line you will see two variables $@ and $<. 
# $@ will match the target and the $< will match the dependency.  So, for
# example, $< will contain main.c whenever $@ contains main.o.
# Note: makefiles are counterintuitive in that the rules don't run in the order
# listed in the file, but instead run whenever they are matched.  Also be careful
# with tabs and spaces.  Rules need a tab (not spaces) before each action.
