And that's exactly the problem. With MSVC, the definition of "debug" and "release" can take one of two meanings: optimised or not versus the runtime it's linking against. By default, people build non-optimised code (/Od) with debugging symbols (/Zi) against the debug runtime (/MDd). But you can compile optimised code (/O2) against the debug runtime (/MDd) and you can compile non- optimised code with debugging symbols (/Od /Zi) against the release runtime (/MD). -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
