Hello,

osra fails to build with openbabel >= 3.2.0 (currently in experimental):

osra_openbabel.cpp: In function 'void create_molecule(OpenBabel::OBMol&, 
std::vector<atom_s>&, const std::vector<bond_s>&, int, double,

std::__cxx11::basic_string<char> >&, int, std::string*, bool, const 
std::vector<bracket_t>&)':

I do not know what might be wrong, thus I am hoping the upstream will 
solve the issue.
