tell make file not to compile debug code
 

Hi all
I've been trying to work out a way to stop chunks of code being compiled using a variable in my makefile but can't work it out. What I mean is for example in my code I might have.

/****output comms portdata********/
printf("\n debug comms port %d",ReadPort("ttys1);


I only wish this code to be compiled when I'm debugging.

What I've tried is using #ifdef with

#ifdef COMM_PORT_DEBUG
printf("\n debug comms port %d",ReadPort("ttys1);
#endif


Then in my make file I set COMM_PORT_DEBUG to 1 so

DEBUG_DEFS = COMM_PORT_DEBUG=1

I then thought I could put it into my in my link line

all:
$(CC) $(CPFLAGS) $(DEBUG_DEFS) $(INC_PATHS) $(SOURCE) -o $(PROGRAM) $(LIB_DIRS) $(GAME_LIBS)

but this gives a

gcc: COMM_PORT_DEBUG=1: No such file or directory


is there a way to do this sort of thing? Or am I barking up the wrong tree? Thanks!

are you missing the -D switch?
