Error C2143: syntax error : missing ';' before 'namespace'

Question

I am VERY new to C++ and Open GL and I have been trying to display 3D objects in a scene. it worked fine with one but when I tried to alter my code to add a second, my code regarding the HUD text showing the camera location started giving errors. The error above is shown and it is apparently in the sstream file (#include). I have tried searching around and asking for help but there is nothing that helps/that I understand. When I comment-out the #include line and the code that uses it, I get a similar saying "error C2143: syntax error : missing ';' before 'using'" in my main.cpp file.

I am running Visual Studio 2010 and I have even tried turning the whole thing off and on again, and copying the code over to a new project. Help would be greatly appreciated.

#include <Windows.h>
#include <GL/gl.h>
#include <GL/glu.h>
#include "glut.h"
#include "SceneObject.h"
#include <fstream>
#include <sstream>
#include <iostream>
#include <string>
//#include <cmath>
//#include <limits>
//#include <cstdlib>

using namespace std;

...

stringstream ss;
ss << "Camera (" << cam.pos.x << ", " << cam.pos.y << ", " << cam.pos.z << ")";
glClear(GL_DEPTH_BUFFER_BIT);
outputText(-1.0, 0.5, ss.str());

I haven't changed the code and as far as I am aware, there are semi-colons where there are meant to be. Even my friend who has been programming for 5 years couldn't solve this. I will include any other specific code if needed. And when I said new to C++ and OpenGL I really much VERY new. This is even my first post. I'll get there eventually.

Answer 1

you have to put a ';' after each class

That means

class foo{
public:
   void bar();
};

and i think you miss the last semicolon.

Answer 2

Every including/function/call etc. has a body wich executes a line of code, because C++ ignores whitespace you will need to tell the program when the line stops this would run only an action and not confuse it with others, to tell your program when an action ends you put a ";"

Because you need to compile C++ apps you will run into an error when you don't do this right. wich is the error you are running into so find out where you miss the ";" and add it

I hope this helps you out.

Answer 3

Your class SceneObject does not have a ; at the end. This is probably the missing ; the error message is referring to. It is most likely causing your problems once you include the header in your code.

This is exactly what Mat and David suggested before.

Answer 4

You should look at all files you included in this one. Perhaps in "SceneObject.h".. seems to be a lack of ";" but also verifies the "{" "}" and "(" ")" because mistakes can sometimes be a bit tricky.
