Hello, when generating binding code using Py++ i got following warnings: WARNING: hapl::Fenotype const * hapl::Fenotypes::find_equal(hapl::Fenotype const & pattern) const [member function] > compilation error W1050: The function returns "hapl::Fenotype const *" type.

boost::python::detail::specify_a_return_value_policy_to_wrap_functions_returning<const hapl::Haplotype*>) (const hapl::Haplotype*)' this is strange for me bacause I'm sure I listed all methods returning mentioned types. There is also one more type that doesn't cause warning: '(const hapl::Genotype*' So I guess this problem may be caused by typedef declaration in my header files: typedef std::map<const Haplotype*,double> ProbHaplotype; typedef std::map<const Fenotype*,double> ProbFenotype; typedef std::map<const Genotype*,double> ProbGenotype; and: typedef std::set<const Fenotype*> ObsFenotypes; typedef std::set<const Genotype*> ObsGenotypes; typedef std::set<const Haplotype*> ObsHaplotypes; STL generic containers can generate methods returning problematic types so i cannot see it in my headers. To solve this problem I replaced lines with call polices mentioned above by: mb.member_functions(return_type='hapl::Fenotype const *').call_policies = module_builder.call_policies.return_internal_reference() mb.member_functions(return_type='hapl::Haplotype const *').call_policies = module_builder.call_policies.return_internal_reference() mb.member_functions(return_type='hapl::Genotype const *').call_policies = module_builder.call_policies.return_internal_reference() but this causes run time error: Traceback (most recent call last): File "makewindow.py", line 27, in <module> mb.member_functions(return_type='hapl::Fenotype const *').call_policies = module_builder.call_policies.return_internal_reference() File "/usr/lib/python2.5/site-packages/pyplusplus/module_builder/builder.py", line 564, in member_functions , recursive=recursive) File "/usr/lib/python2.5/site-packages/pygccxml/declarations/scopedef.py", line 518, in member_functions , allow_empty=allow_empty) File "/usr/lib/python2.5/site-packages/pygccxml/declarations/scopedef.py", line 374, in _find_multiple raise RuntimeError( "Multi declaration query returned 0 declarations." ) RuntimeError: Multi declaration query returned 0 declarations. So what shuld I do to get clean complation without errors? -- Regards Michał Nowotka _______________________________________________ Cplusplus-sig mailing list Cplusplus-sig@python.org http://mail.python.org/mailman/listinfo/cplusplus-sig
