Good afternoon, I've so far managed to make decent progress on building RC 1.34's Boost.Python on this OS/Compiler combination using jam v1 with the patches I submitted earlier. Unfortunately I now seem to have hit a brick wall in file pickle_support.cpp. The offending lines of code are line 57, which reads: static object result(&instance_reduce); If I replace this line with plain static object result; the file will compile, however the above line produces the following error message from the compiler: sunpro-C++-action bin/boost/libs/python/build/libboost_python.so/sunpro/debug/pickle_support.o "./boost/python/converter/arg_to_python.hpp", line 215: Error: Could not find boost::python::converter::detail::arg_to_python_base::arg_to_python_base(boost::python::tuple(*)(boost::python::api::object), const boost::python::converter::registration) to initialize base class. "./boost/python/object_core.hpp", line 309: Where: While instantiating "boost::python::api::object_base_initializer<boost::python::tuple(*)(boost::python::api::object)>(boost::python::tuple(*const)(boost::python::api::object)&)". "./boost/python/object_core.hpp", line 309: Where: Instantiated from non-template code. 1 Error(s) detected I think I'm missing something obvious here but I'm not familiar enough with the Boost.Python code to work out what it is. I'd appreciate if someone who is would be able to have a closer look as this is the last file that doesn't build here. Regards, Timo
