Indeed, but QList has a toSet method and QSet needs hashing ... It's hard to say why some compilers do the unnecessary instantiation and what makes them to do it - I'm only guessing too. > Can you give me the stack of instentiation that code an instentiation of > qHash(double). You told me qhash.h(875), but it does not tell me what > instantiate QHash<double, ???> The problem is reported in different ways ( with different workarounds ) on the Qwt support channels but seems to be related to the following line in qwt_valuelist.h: template class __declspec(dllexport) QList<double>; This declaration is for building the Qwt library itsself ( not for using it ) on Windows. You can download the Qwt library (version 5.2 ) here: http://sourceforge.net/projects/qwt . It can be build with qmake + make.
