GLFW linking issue Visual Studio 2012

问题

This is driving me mad, I want to statically link to GLFW.lib, following section 4.2.1. of the readme.html file provided I have added glfw.lib and opengl32.lib to the additional dependancies section of the linker on VS.

I've also added the dir including glfw.lib to the additional library directories section under linker > general.

And of course I have included the glfw.h file in my project, yet I'm still getting...

Error   1   error LNK2019: unresolved external symbol _glfwInit referenced in function _main    C:\Users\Smith_000\Documents\Visual Studio 2012\Projects\Spark\Spark\main.obj   Spark

Error   7   error LNK1120: 6 unresolved externals   C:\Users\Smith_000\Documents\Visual Studio 2012\Projects\Spark\Debug\Spark.exe  1   1   Spark

With the following (example) code...

#include <glfw.h>
#include <stdlib.h>

int main( void )
{
    int running = GL_TRUE;

    // Initialize GLFW
    if( !glfwInit() )
    {
        exit( EXIT_FAILURE );
    }

    // Open an OpenGL window
    if( !glfwOpenWindow( 300,300, 0,0,0,0,0,0, GLFW_WINDOW ) )
    {
        glfwTerminate();
        exit( EXIT_FAILURE );
    }

    // Main loop
    while( running )
    {
        // OpenGL rendering goes here...
        glClear( GL_COLOR_BUFFER_BIT );
        // Swap front and back rendering buffers
        glfwSwapBuffers();
        // Check if ESC key was pressed or window was closed
        running = !glfwGetKey( GLFW_KEY_ESC ) &&
        glfwGetWindowParam( GLFW_OPENED );
    }

    // Close window and terminate GLFW
    glfwTerminate();

    // Exit program
    exit( EXIT_SUCCESS );
}

What am I doing wrong?

回答1:

Make sure you have glfw.dll in folder with your .exe file. If this wont help, add another library glu32.lib.

I use to add libraries in code by adding this before main function. With this you see wich libraries you have linek without diging through options and menus.

#pragma comment(lib, "GLFW.lib")
#pragma comment(lib, "opengl32.lib")
#pragma comment(lib, "glu32.lib")

回答2:

Perhaps the reason is because you are linking to these libraries in only one build mode, say, release.

Second possible reason: (Correct me if I am wrong, as I am not 100% sure of this). The LIB files might have been built in different compiler. For example, the LIB was compiled in MinGW, and you are linking to it with the MSVC++ compiler.

Third possible reason: Consider what version of GLFW you are using (As in 32 bit, 64 bit).
