[Boost-users] [MPL] Generate template instantiation ?

Hi all, I have a class templated on 2 arguments, e.g. : template <typename PixelType , typename NbChannels> class myClass { // ... }; This class is in a lib, and I would like to instantiate it for all base type (signed char, unsigned char, int, unsigned int ...), and for a given number of channels. For example : template class myClass<unsigned char,1>; template class myClass<unsigned char,2>; // ... template class myClass<unsigned char,10>; template class myClass<signed char,1>; template class myClass<signed char,2>; // ... template class myClass<signed char,10>; And so on. Is there a way to do this without writing all possiblities. Maybe with the MPL ? Best regards, Olivier
