I'm working on a C++ header file and I keep getting the error "Unknown type name 'string'; did you mean 'std::string'?" #include <string> is already at the top of my code, so I'm not sure how else to remedy this issue. Any thoughts? I'm using Xcode, if that makes any difference.
#ifndef POINT_HPP #define POINT_HPP #include <string> using namespace std; class Point { public: Point(); Point(int pInitX, int pInitY); Point(int pInitX, int pInitY, int pInitColor); double distance(Point pAnotherPoint); int getColor(); int getX(); int getY(); void move(int pNewX, int pNewY); void setColor(int pNewColor); void setX(int pNewX); void setY(int pNewY); string toString; // Error: Unknown type name 'string'; did you mean 'std::string'? private: void init(int pInitX, int pInitY, int pInitColor); int mColor; int mX; int mY; }; #endif 2 Answers
you must use std::string toString()or declare using namespace std;globally
Make sure to also set the path to the Point class (header and cpp) inside CMakeLists.txt.
If you are using QT, it should be something like
set(PROJECT_SOURCES ... point.cpp point.h ) After that you need to import the string class at the top like this #include <string> and then declare using namespace std;
