The most recent openbabel-devel rpm package for Fedora 22
openbabel-devel-2.3.2-11 still has in shared_ptr.h
#ifdef USE_BOOST
#include <boost/shared_ptr.hpp>
#define shared_ptr boost::shared_ptr
#else
#include <memory>
#if __GNUC__ == 4 //&& __GNUC_MINOR__ < 3 removed at the suggestion of
Konst
antin Tokarev
#include <tr1/memory>
#endif
using std::tr1::shared_ptr;
#endif
The current version of GCC on Fedora 22 is gcc-5.1.1-4.fc22 and it comes
with
shared_ptr in std. I realize this has most likely been fixed already in OB
source,
but the rpm package is still in fedora repos and is rather unusable.
Just thought I point it out.
And for those who will google this message with the same problem -
error: 'std::tr1' has not been declared
here is the trivial fix - put the following in
/usr/include/openbabel-2.0/openbabel/shared_ptr.h
#ifdef USE_BOOST
#include <boost/shared_ptr.hpp>
#define shared_ptr boost::shared_ptr
#else
#include <memory>
#if __GNUC__ == 4
#include <tr1/memory>
#endif
#if __GNUC__ < 5
using std::tr1::shared_ptr;
#else
using std::shared_ptr;
#endif
#endif
Your code will probably need to be compiled with -std=c++11 option.
