I have reproduced the compilation problem in Ubuntu 12.04, gcc-4.6.3. In CentOS with gcc-4.4.6 there is no such problem.
Solution: Put $(LDFLAGS) at the end of the linking line as follows: $(CC) example.o -o example $(LDFLAGS) P.S. When executing the examples don't forget to set LD_LIBRARY_PATH=$OB_PREFIX/lib BABEL_LIBDIR=$OB_PREFIX/lib/openbabel/2.3.2 BABEL_DATADIR=$OB_PREFIX/share/openbabel/2.3.2 Good Luck, Igor Leontyev ------------------------------------------------------------------------------ Rapidly troubleshoot problems before they affect your business.
