I'm trying to learn OpenGL. I'm using the SFML window module for the context and gl3w as my loading library. I use SFML pretty often so it wasnt a problem to set it up for OpenGL following this tutorial:http://www.sfml-dev.org/tutorials/2.0/window-opengl.php
I could run the example code without any problems. I linked everything that I need for OpenGL (opengl32.lib and glu32.lib + sfml*.lib).
Then I followed this answer to get gl3w :How to set up gl3w on Windows?.
But now if I try to run this code which is mostly the example code from SFML
#include <SFML/gl3w.h>
#include <SFML/Window.hpp>
static const GLfloat red[] = { 1.0f, 0.f, 0.f, 1.f };
int main()
{
// create the window
sf::Window window(sf::VideoMode(800, 600), "OpenGL", sf::Style::Default, sf::ContextSettings(32));
window.setVerticalSyncEnabled(true);
gl3wInit(); //ignore return value for now
// load resources, initialize the OpenGL states, ...
// run the main loop
bool running = true;
while (running)
{
// handle events
sf::Event event;
while (window.pollEvent(event))
{
if (event.type == sf::Event::Closed)
{
// end the program
running = false;
}
else if (event.type == sf::Event::Resized)
{
//adjust the viewport when the window is resized
glViewport(0, 0, event.size.width, event.size.height);
}
}
glClearBufferfv(GL_COLOR, 0, red);
// end the current frame (internally swaps the front and back buffers)
window.display();
}
// release resources...
return 0;
}
I get following Linker errors.
1>OpenGL.obj : error LNK2019: unresolved external symbol _gl3wInit referenced in function _main
1>OpenGL.obj : error LNK2001: unresolved external symbol _gl3wViewport
1>OpenGL.obj : error LNK2001: unresolved external symbol _gl3wClearBufferfv
I double checked if I linked the libs correctly.
Im working on Windows 7 with Visual Studio 2013.
Anyone knows what I do wrong?
