1) you cannot link both qtmain and qtmaind: first one is release version, second one is debug -> linker will only use the first one anyway
2) you also need QtCore.lib, QtGui.lib etc
hmh... i just tested link both of them, but i dont have any QtCore, QtGui libs
in lib folder is only some .a and .prl files. I've run config but while running nmake come some damn error (link error) and operation aborts with error code 0x2Edit: nmake error comes on file qdom.cpp, qxmlutils_p.cpp qxml.cpp
