I made the 'make', 'make check' and 'make install'. Then try the hs071_cpp example using the 'Makefile' created duing the installation and all worked fine, the problem was solved. But I want to use Ipopt with other libreries like 'openmi' and so I first tried to build the example program from the terminal of linux.
