# Makefile for tiny pascal compiler example.

# the tinypascal executable tp is produced by linking 3 .o files, + libraries
tp: lex.yy.o tpgram.tab.o tp.o
	gcc -o tp lex.yy.o tpgram.tab.o tp.o -lfl

#
# .o files are compiled from .c files via "gcc -c". Could add -g for debugging.
# If a .c file includes a .h file, the .o "depends" on that .h file too.
