[osg-users] Copy constructor for Vec3 or Quat
Hi Robert, I was just wondering if it's intended that the Vec3 or Quat classes don't have a copy constructor of the form : Vec3f( const Vec3f vec3 ) Can I add them or is there any reason for that . Thanks ! -- Serge Lages http://www.tharsis-software.com ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Let's explain a bit my problem : I would like to use the any class from the Boost library ( http://www.boost.org/doc/libs/1_35_0/doc/html/any.html), but it doesn't work with Vec3 or Quat types (but it works with Matrix for example). I have this compile error : error LNK2019: unresolved external symbol public: __thiscall osg::Vec3d::Vec3d(class osg::Vec3d const ) That's why I was thinking that it has something to do with the fact that Matrix implement its copy constructor and not the Vec3 or Quat classes. I've made some tests and actually it only works with classes implementing explicitly their copy constructors. So should it be possible to add copy constructors to these classes ? :) Ok, not sure, but I expect this a bug in the c++ compiler. Anyway, may be Robert will accept a workaround patch for that ...
