I worked on a similar problem last week. You probably have conflicting settings for wchar_t. Apparently, Qt's binaries all have the built-in wchar_t type disabled. You can see this if you use dumpbin on any of their binaries. No wchar_t anywhere. Everything will be const char*. What you need to do is invoke Boost jam with the cxxflags=-Zc:wchar_t- parameter. By default, Boost has Zc:wchar_t  set, and setting this flag will override that setting. You can also modify the jamfile to change it to the Zc:wchar_t- version.
