Glew - Linking Error on gl- function symbols when paired with GLFW

Question

I was reworking a project to use GLFW in opposed to FreeGLUT, and I think I must've managed to delete something in my linker settings. I'm using GLEW, and while I initially thought I had untethered it somehow, its not giving me an error for all GLEW-related function calls, only a couple. I've checked the changes I made to property files using git, and the only change is replacing freeglut.lib with glfwdll.lib

The error messages:

1>main.obj : error LNK2019: unresolved external symbol __imp__glBlendFunc@8 referenced in function "void __cdecl display(void)" (?display@@YAXXZ)

Then, my main() function, which is the only function that ended up changing during the transition:

void main(int argc, char** argv) 
{
if (!glfwInit())
{
    exit(-1);
}
glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_COMPAT_PROFILE);

GLFWwindow* window = glfwCreateWindow(width, height, "Space Invaders", NULL, NULL);
if (window == NULL)
{
    std::cout << "Failed to create GLFW window" << std::endl;
    glfwTerminate();
    endGame(-1);
}
glfwMakeContextCurrent(window);
glViewport(0, 0, width, height);

// A call to glewInit() must be done after GLFW is initialized!
GLenum res = glewInit();
// Check for any errors
if (res != GLEW_OK) {
    fprintf(stderr, "Error: '%s'\n", glewGetErrorString(res));
    endGame(1);
}

gameState = new GameState();

init();

while (!glfwWindowShouldClose(window))
{
    pollInput(window);
    display();
    glfwSwapBuffers(window);
    glfwPollEvents();
}
endGame(0);
}

I've noticed that each of the functions throwing errors have the gl- prefix rather than glew-, do I need to add another library now that I'm not using freeglut? I'm currently only linking glfw and glew.

好的，我不确定以前没有它如何管理，但是我也需要链接OpenGL32.lib 。
