Thank you for your answers. Moving -lopenbabel didn't work for me, but using Noel's suggestion I found a way to make a working Makefile (even if cmake is working perfectly fine).
If someone faces the same problems, here is my Makefile: TARGET =example.exe SOURCES =example.cpp OBJECTS =$(SOURCES:.cpp=.o) CC =g++ CFLAGS =-O2 -Wall INCLUDE =-I/home/nicolas/Programmes/OpenBabel-2.3.2/include/openbabel-2.0 LDFLAGS =-rdynamic /home/nicolas/Programmes/OpenBabel-2.3.2/lib/libopenbabel.so -Wl,-rpath,/home/nicolas/Programmes/OpenBabel-2.3.2/lib LIBS =-lm all: $(TARGET) $(TARGET): $(OBJECTS) $(CC) $(OBJECTS) -o $(TARGET) $(LDFLAGS) .cpp.o: $(CC) $(CFLAGS) $(INCLUDE) $(LIBS) -c $< -o $@ clean: rm *.o Nicolas -- View this message in context: http://forums.openbabel.org/Problem-for-compiling-the-example-files-tp4656837p4656892.html Sent from the General discussion mailing list archive at Nabble.com. ------------------------------------------------------------------------------ Shape the Mobile Experience: Free Subscription Software experts and developers: Be at the forefront of tech innovation.
