Link Mosquitto with gcc on OSX

Question

I am new to Mosquitto and I am tying to write a simple C client connecting to Mosquitto's test server: http://test.mosquitto.org/

Here is the code of the simple C client which is 99.9% of an example found on Mosquitto's site: http://pastie.org/private/orwicqjfjz8g8biurznca

EDIT 1:

I followed the comments and wrote a makefile instead of doing

gcc -o test test.c

The makefile looks like this:

CC = gcc
CFLAGS = -I
DEPS = mosquitto.h

LIBS = -llibmosquitto

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

make: test.c
    $(CC) -m32 -Wall -o $@ $^ $(CFLAGS) $(LIBS)

.PHONY: clean

This is the output i get which seems to be some problem linking mosquitto libs with gcc:

Undefined symbols for architecture i386:

  _main in cc6Blyda.o
  "_mosquitto_connect_callback_set", referenced from:

  _main in cc6Blyda.o
ld: symbol(s) not found for architecture i386
collect2: ld returned 1 exit status
make: *** [make] Error 1

NOTE: I used homebrew to install the mosquitto so the path to the lib is

/usr/local/Cellar/mosquitto/1.1/

Appreciate any help!!

Answer 1

I solved the linking problem by some trial error in my makefile.

This is how the final makefile looks like which does not give any linking problems:

CC = gcc

LIBS = -lmosquitto

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

make: test.c
    $(CC) -Wall -o test $^ $(LIBS)

.PHONY: clean

Thanks
