c++ - Glew - 与 GLFW 配对时 gl- 函数符号的链接错误

Question

我正在重新设计一个项目以使用 GLFW 而不是 FreeGLUT，我想我一定设法删除了我的链接器设置中的某些内容。我正在使用 GLEW，虽然我最初认为我已经以某种方式解开了它，但它并没有给我所有与 GLEW 相关的函数调用的错误，只有几个。我已经检查了我使用 git 对属性文件所做的更改，唯一的更改是将 freeglut.lib 替换为 glfwdll.lib

错误信息:

然后，我的 main() 函数，这是唯一在转换期间最终发生变化的函数:

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);
}

我注意到每个抛出错误的函数都有 gl- 前缀而不是 glew-，既然我没有使用 freeglut，我还需要添加另一个库吗？我目前只链接 glfw 和 glew。

好吧，我不确定以前没有它我是如何管理的，但我还需要链接 OpenGL32.lib。
