Can't include a directory in my newbie Makefile

Question

Simply I am trying to get ImageMagick headings into my newbie make scheme. Why is it still giving me 'no such file or directory' error?

CC=g++
CFLAGS=-c -I/usr/local/include/ImageMagick-7/ 

all: go

go: demo.o
    g++ demo.o -o test

demo.o: demo.cpp
    g++ -C demo.cpp

cleanup:
    rm *.o

Answer 1

You have declared the flags but you have not included the variable in the compile step. Change your makefile to this

CC=g++
CFLAGS=-c -I/usr/local/include/ImageMagick-7/ 

all: go

go: demo.o
    $(CC) demo.o -o test

demo.o: demo.cpp
    $(CC) $(CFLAGS) demo.cpp

cleanup:
    rm *.o
    rm test
