Makefile

#
# A simple makefile for managing build of project composed of C source files.
# References: https://web.stanford.edu/class/cs107/resources/make

# It is likely that default C compiler is already gcc, but explicitly
# set, just to be sure
CC = gcc

# The CFLAGS variable sets compile flags for gcc:
#  -g          compile with debug information
#  -Wall       give verbose compiler warnings
#  -O0         do not optimize generated code
#  -std=gnu99  use the GNU99 standard language definition
CFLAGS = -g -Wall -O0 -std=gnu99

# The LDFLAGS variable sets flags for linker
#  -lm   says to link in libm (the math library)
LDFLAGS = -lm

# In this section, you list the files that are part of the project.
# If you add/change names of source files, here is where you
# edit the Makefile.
SOURCES = demo.c vector.c map.c
OBJECTS = $(SOURCES:.c=.o)
TARGET = demo


# The first target defined in the makefile is the one
# used when make is invoked with no argument. Given the definitions
# above, this Makefile file will build the one named TARGET and
# assume that it depends on all the named OBJECTS files.

$(TARGET) : $(OBJECTS)
	$(CC) $(CFLAGS) -o $@ $^ $(LDFLAGS)

# Phony means not a "real" target, it doesn't build anything
# The phony target "clean" is used to remove all compiled object files.
# 'core' is the name of the file outputted in some cases when you get a
# crash (SEGFAULT) with a "core dump"; it can contain more information about
# the crash.
.PHONY: clean

clean:
	rm -f $(TARGET) $(OBJECTS) core
