I'm trying to build an OpenGL App with glew/glfw. I've downloaded the binaries, placed them in the root of my folder, added the paths to the include and lib directories and told my project to require glew32.lib, GLFW.lib and opengl32.lib.
I even copied glew32.lib to the root directory because my project couldn't see it.
I must keep all the dependencies in the project directory since I will be distributing this. I'm at a loss.
Now when I run my program, it fails at glewInit()
This is my implementation so far:
#include "Common.h"
GameEngine::GameEngine()
{
InitWithSize(1024, 768);
InitInput();
}
void GameEngine::InitWithSize(int _width, int _height)
{
try {
// Initialise GLFW
if( !glfwInit() )
throw std::exception("Failed to initialize GLFW\n");
//glfwOpenWindowHint(GLFW_FSAA_SAMPLES, 4);
glfwOpenWindowHint(GLFW_OPENGL_VERSION_MAJOR, 3);
glfwOpenWindowHint(GLFW_OPENGL_VERSION_MINOR, 3);
glfwOpenWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
// Open a window and create its OpenGL context
if( !glfwOpenWindow( _width, _height, 0,0,0,0, 32,0, GLFW_WINDOW ) )
throw std::exception("Failed to initialize GLFW\n");
glfwSetWindowTitle( "Tutorial 01" );
// Initialize GLEW
if (glewInit() != GLEW_OK)
throw std::exception("Failed to initialize GLEW\n");
} catch ( std::system_error const& err) {
fprintf(stdout, "System Error: %s", err.what());
glfwTerminate(); // Free glfw if it has been allocated
// Try Again
this->InitWithSize(_width, _height);
} catch( std::exception const& err) {
fprintf(stdout, "Exception Found: %s", err.what());
} catch ( ... ) {
fprintf(stdout,"Unknown Exception Occurred\n");
}
}
void GameEngine::InitInput()
{
// Ensure we can capture the escape key being pressed below
glfwEnable( GLFW_STICKY_KEYS );
}
void GameEngine::StartGameLoop()
{
do{
// Draw nothing, see you in tutorial 2 !
// Swap buffers
glfwSwapBuffers();
} // Check if the ESC key was pressed or the window was closed
while( glfwGetKey( GLFW_KEY_ESC ) != GLFW_PRESS &&
glfwGetWindowParam( GLFW_OPENED ) );
}
void GameEngine::InitTestData()
{
// An array of 3 vectors which represents 3 vertices
static const GLfloat g_vertex_buffer_data[] = {
-1.0f, -1.0f, 0.0f,
1.0f, -1.0f, 0.0f,
0.0f, 1.0f, 0.0f,
};
}
With my Common Header:
#ifndef _COMMON_H
#define _COMMON_H
// OpenGL Libraries
#define GLEW_STATIC
//#pragma comment(lib, "glew32.lib")
#include <GL\glew.h>
#include <GL\glfw.h>

#endif
I know this answer comes a bit late, but I don't see you making the OpenGL context current by calling glfwMakeContextCurrent(window)
. You have to do that before calling glewInit()
