General / Problem with compiling SFML project in 2008

« on: May 05, 2013, 05:08:19 pm »

Ok, I have created SFML solution 2008 with CMake. Now I want to build it, but I get errors like this:

Error   25   error LNK2019: unresolved external symbol __imp__glEnable@4 referenced in function "private: void __thiscall sf::priv::GlContext::initialize(void)" (?initialize@GlContext@priv@sf@@AAEXXZ)   GlContext.obj   sfml-window

and so on. I understand that it can't find external libraries, but how can I fix this?

Thank's for help.
PS Windows 7 x64(but I'm using SFML for x32 platform), CMake 2.8.10.2, latest SFML source,

Graphics / How to quickly draw image by pixel? SFML 2

« on: October 26, 2012, 07:40:34 am »

I use this code:

sf :: Image image;
image.create(1024, 768, sf :: Color());

sf :: Texture texture;
texture.loadFromImage(image);

sf :: Sprite sprite(texture);

// some code here

for ( int i = 0; i < WIDTH; ++i )
        for ( int j = 0; j < HEIGHT; ++j )
                image.setPixel(i, j, f(t, i, j, image.getPixel(i, j)));
texture.loadFromImage(image);
 

But I think this isn't quick solution. Can You help?

Graphics / Problem with inheritance from Drawable

« on: October 04, 2012, 09:03:31 pm »

I'm trying to create this class from Drawable, but I get:

error C2259: 'Triangle' : cannot instantiate abstract class in Visual Studio 2008
I'm using sfml 1.6
This is my code. Thank's for any help.

class Triangle : public sf :: Drawable
{
public:
        Triangle () { };
        Triangle ( sf::Vector2f Pos, sf::Vector2f Scale, float Rotation, sf::Color Color ) { };
        ~Triangle () { };
        void Render ( sf :: RenderTarget& Target ) { };
};
