How do I add a debug option to Makefile

Question

I\'ve got the below simple Makefile which I use for compiling a C program:

all:
    gcc -Wall -o myfile myfile.c lol_dht22/dht22.c lol_dht22/locking.c -lwiri         


        

Answer 1

Here's an example makefile that has the two options you are looking for.

all:
    gcc -Wall -o myfile myfile.c lol_dht22/dht22.c lol_dht22/locking.c -lwiringPi -lcurl -lm
debug:
    gcc -DDEBUG -Wall -o myfile myfile.c lol_dht22/dht22.c lol_dht22/locking.c -lwiringPi -lcurl -lm

You just needed to add a debug option, which is done in similar fashion to the 'all' option you had already declared.
