You attempted to call a non-const member function on p, which is reference to a const AguiPoint. Since references are aliases to the original object, calling a non-const member function on a const AguiPoint & is equivalent to calling a non-const member function on a const AguiPoint, which is an error. It's an error because since the method was not declared

Somehow I was using source code files from another folder, for another project, to compile. Was opening the files from Windows explorer and seeing all the consts as they should be, then realised that opening c2662 cannot convert the "same files" from within the Solution Explorer showed different contents. Further checking showed the files associated with the project I was trying to build were not the files I was currently editing. Lesson learned - be more careful with version control. Thanks for the comments, they helped me look down the right lines and stop banging my head off the keyboard looking for a typo. ======================================================== I'm getting multiple "error C2662"s errors in the following code (positions shown in comments): XYVector Rocket::avoidRocketsAndPlanets(float distance, const std::set& otherRockets, const std::set& planets) const { XYVector c = XYVector(); for (std::set::const_iterator it = otherRockets.begin(); it != otherRockets.end(); it++) { if ((it->getPos() - pos).mod() < distance) { c -= (it->getPos() - pos); } } for (std::set::const_iterator it = planets.begin(); it != planets.end(); it++) { XYVector planetPos = it->getPos(); // ^ error C2662: 'Planet::getPos' : cannot convert 'this' pointer from 'const Planet' to 'Planet &' if ((planetPos - pos).mod() < (distance + it->getRadius())) // ^ error C2662: 'Planet::getRadius' : cannot convert 'this' pointer from 'const Planet' to 'Planet &' { c

Substituting there is a type mismatch between 'const std::vector' to 'std::vector &', you can not convert between a const object an a non-const reference to an object. Now look at your function Expand|Select|Wrap|Line Numbers voidcustomer::add_movie(stringmove)const { intflag1=0; for(unsignedinti=0;i movies. See any const qualifiers? Yes on the func
