Hi I think template template template parameters are a very useful tool to make your code as abstract and universal as possible. The problem is that my compiler, g++, doesn't seem to share my enthusiasm and refuses to compile my templates // I declared these classes and functions: // ... template class TSegment, class TElem, class TOut = TElem> class SegmentedPath; // ... template class SplineSegment; // ... class Vec2d; // ... template class, class, class> class TSegPath, class TElem, class TOut = TElem> void calc_splines_curve(TSegPath&, bool, int, int); // The problem occurs as soon as I call this function, using the code // ... SegmentedPath spl; // ... calc_splines_curve(spl, true, 0, 10); // or, as an alternative calc_splines_curve (spl, true, 0, 10); // where true, 0, 10 are not that important for the error /* the error reads: fraser [17:37] polyliner 125) g++ -o testio testio.cpp ioplus.cpp calc_splines.cpp: In function `void calc_splines_curve TSeg, class TElem, class TOut = TElem> SegmentedPath, Vec2d, Vec2d>(SegmentedPath &, bool, int, int)': testio.cpp:47: instantiated from here calc_splines.cpp:140: Internal compiler error. calc_splines.cpp:140: Please submit a full bug report. calc_splines.cpp:140: Internal compiler error: calc_splines.cpp:140: See for instructions. */ does anyone have an idea to this? greetings, a.h ______________________________________________________________________________ Horoskop, Comics, VIPs, Wetter, Sport und Lotto im WEB.DE Screensaver1.2 Kostenlos downloaden: http://screensaver.web.de/?mc=021110
