Build brief module - c++

Question

I trying to build brief software. Firstly I create the ./lib/libbrief.so, and secondly I am trying to build main file. The makefile which included in .zip file:
CC=g++
SOURCES=main.cpp
OBJECTS=$(SOURCES:.cpp=.o)
EXECUTABLE=main
//#Only enable -msse4.2 on CPUs supporting the POPCNT instruction
CFLAGS = -Wall -DNDEBUG -O3 -march=nocona #-msse4.2
//#CFLAGS = -Wall -DDEBUG -g -O0 -fno-inline-functions
LDFLAGS = -Wl
//# BRIEF
CFLAGS += -I../brief/include
LDFLAGS += -L../brief/lib -lbrief
//# OpenCV
CFLAGS += `pkg-config opencv --cflags`
LDFLAGS += `pkg-config opencv --libs`
all: $(SOURCES) $(EXECUTABLE)
$(EXECUTABLE): $(OBJECTS)
$(CC) $(LDFLAGS) $(OBJECTS) -o $#
.cpp.o:
$(CC) -g -c $(CFLAGS) $< -o $#
clean:
rm -f $(OBJECTS) $(EXECUTABLE) matches.png
However I am getting errors, related with opencv. The errors found:
g++ -Wl -L../brief/lib -lbrief `pkg-config opencv --libs` main.o -o main

What have to do to build proper the main.cpp?

Answer 1

You must list all the object files on the link like before the libraries that they use.
See, for example, Why does the order in which libraries are linked sometimes cause errors in GCC?
