[cherrybombuc]

Hi
I'm new on c, I want to add WirringPi on this makefile. I don't know the way. please.

Code: Select all

CFLAGS = -O2 -Wall
CC = gcc
INSTALL = install
TARGET = /usr/sbin

LIB_OBJS=command.o controller.o emitter.o init.o log.o monitor.o navdata.o network.o pilot.o web.o
PROG_OBJS=arpilot.o
LIB=arpilot.a
PROG=arpilot

all: lib arpilot 

.c.o:
	$(CC) -c $(CFLAGS) -o $@ $<

lib: $(LIB_OBJS)
	ar r $(LIB) $(LIB_OBJS)

arpilot: $(PROG_OBJS) lib
	$(CC) $(CFLAGS) $(PROG_OBJS) $(LIB) -o $(PROG)

install: $(PROG)
	$(INSTALL) $(PROG) $(TARGET)/$(PROG)

clean:
	rm -f $(PROG_OBJS) $(LIB_OBJS) $(PROG) $(LIB)

install: $(PROG)

clean:
	rm -f $(PROG_OBJS) $(LIB_OBJS) $(PROG) $(LIB)

Add a separate line after your LIB=arpilot.a line:

Code: Select all

EXTRA_LIBS=-lwiringPi

then in your link section (make target arpilot: append

Code: Select all

$(EXTRA_LIBS)

so it looks like:

Code: Select all

arpilot: $(PROG_OBJS) lib
   $(CC) $(CFLAGS) $(PROG_OBJS) $(LIB) -o $(PROG) $(EXTRA_LIBS)

If using trig/math functions, you can add -lm after -lwiringPi too (and any other system libs if needed)

Did you follow Gordon's instructions exactly? to the letter?
Perhaps double check it, and post your makefile.
