Thanks to you both, I wrote a makefile which seems to correctly
compile and link:

$ make
g++ -Wall -c occi_dump.cpp
g++ -Wall -c OcciDml.cpp
g++ -Wall -o occi_dump occi_dump.o OcciDml.o

$ cat Makefile
CC = g++
CFLAGS = -Wall
OBJECTS = occi_dump.o OcciDml.o

occi_dump : $(OBJECTS)
$(CC) $(CFLAGS) -o $@ $(OBJECTS)

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

clean:
rm -rf *.o occi_dump
