OpenGL GLFW Errors Source and log in here for resource

Recommended Posts

I'm just working in GLFW this weekend and I have come across an error. I have been able to compile and build the project successfully; however, when trying to run the application to see my work in progress I get the following unresolved external symbol problems.
main.obj : error LNK2001: unresolved external symbol _glfwTerminate
main.obj : error LNK2001: unresolved external symbol _glfwSetWindowTitle
main.obj : error LNK2001: unresolved external symbol __imp__glLoadIdentity@0
MSVCRT.lib(crtexew.obj) : error LNK2001: unresolved external symbol _WinMain@16
C:\Documents and Settings\c.s. Finch\My Documents\Visual Studio 2008\Projects\OpenGL_00\Release\OpenGL_00.exe : fatal error LNK1120: 18 unresolved externals
Build log was saved at "file://c:\Documents and Settings\c.s. Finch\My Documents\Visual Studio 2008\Projects\OpenGL_00\OpenGL_00\Release\BuildLog.htm"
OpenGL_00 - 19 error(s), 0 warning(s)
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

and here is my source code but I don't believe there is a problem with it at all.
#include <windows.h>
#include <gl/gl.h>
#include <gl/glu.h>
#include <gl/glfw.h>
#include <stdlib.h>
#include <stdio.h>
#include <math.h>


void Draw(void)
{
	int width, height;
	double t;

	t = glfwGetTime();

	glfwGetWindowSize(&width, &height);

	height = height < 1 ? 1 : height;

	glViewport(0, 0, width, height);

	glClearColor(0.0f, 0.0f, 0.0f, 0.0f);
	glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

	//set up projection matrix
	glMatrixMode(GL_PROJECTION);
	glLoadIdentity();
	gluPerspective(65.0, (double)width/(double)height, 1.0, 100.0);

	//Set up modelview matrix
	glMatrixMode(GL_MODELVIEW);
	glLoadIdentity();
	gluLookAt(0.0, 0.0, 10.0, 0.0, 0.0, 0.0,0.0, 1.0, 0.0);

}

int main(int agrc, char **argv)
{
	int ok;
	int running;

	glfwInit();

	ok = glfwOpenWindow(640, 480, 8, 8, 8, 8, 24, 0, GLFW_WINDOW);

	if(!ok)
	{
		glfwTerminate();
		return 0;
	}

	//set window title
	glfwSetWindowTitle("My Open GL Beginning");
    
	glfwEnable(GLFW_STICKY_KEYS);

	//Main rendering loop
	do
	{
		Draw();

		glfwSwapBuffers();

		//check if the escape key was pressed, or if window was closed
		running = !glfwGetKey(GLFW_KEY_ESC) && glfwGetWindowParam(GLFW_OPENED);
	}while(running);

	//Terminate GLFW
	glfwTerminate();

	//Exit program
	return 0;
}

Thanks,

If you downloaded glfw-2.6.bin.WIN32.zip you should find glfw.lib in the msvc directory. Link against this. Also for some reason GLFW_BUILD_DLL should be defined for your project since you're using the static lib. This means you don't need the dll.

Just go to properties for your project and add it under Configuration Properties -> C/C++ -> Preprocessor -> Preprocessor Definitions.

You dont need to include gl.h and glu.h separately if you've included glfw.h.

These are what you should link against: glfw.lib opengl32.lib glu32.lib
Add them in Configuration Properties -> Linker -> Input -> Additional Dependencies.

I hope this helps.
