Hi again. John, i checked out the RC_1_29_0 branch a few hours ago, and tried to compile everything. Using bjam everything builds fine, EXCEPT Boost Python... all other libs work as expected using MSVC1310.... Here is the error i get for all the targets of boost python: vc-C++ libs\python\build\bin\boost_python.dll\vc7\debug\runtime-link-dynamic\typ es.obj types.cpp E:\sdk\boost\boost\boost\python\reference.hpp(213) : error C2888: 'boost::shared _ptr' : symbol cannot be defined within namespace 'python' E:\sdk\boost\boost\boost\python\reference.hpp(222) : see reference to cl ass template instantiation 'boost::python::reference<T>' being compiled Maybe this just is not fixed yet... or its an error of mine Till next time Bernhard [Non-text portions of this message have been removed]
