按照 OpenGL 3+ 的一些 OpenGL 教程,一开始我遇到了一些差异,这是我设法获得的代码,但一开始我就得到了大量的错误,没有一个说它找不到包含的头文件,而仅仅是头文件没有定义核心功能。
#include <stdio.h>
#include <stdlib.h>
#include <GL/glew.h>
#include <GL/glfw3.h>
#include <glm/glm.hpp>
int main(){
// Initialise GLFW
if( !glfwInit() )
{
fprintf( stderr, "Failed to initialize GLFW\n" );
return -1;
}
glfwOpenWindowHint(GLFW_FSAA_SAMPLES, 4); // 4x antialiasing
glfwOpenWindowHint(GLFW_OPENGL_VERSION_MAJOR, 3);
glfwOpenWindowHint(GLFW_OPENGL_VERSION_MINOR, 3);
glfwOpenWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE); //I don't want the
//old OpenGL
// Open a window and create its OpenGL context
if( !glfwOpenWindow( 1024, 768, 0,0,0,0, 32,0, GLFW_WINDOW ) )
{
fprintf( stderr, "Failed to open GLFW window\n" );
glfwTerminate();
return -1;
}
// Initialize GLEW
glewExperimental=true; // Needed in core profile
if (glewInit() != GLEW_OK) {
fprintf(stderr, "Failed to initialize GLEW\n");
return -1;
}
glfwSetWindowTitle( "Tutorial 01" );
// Ensure we can capture the escape key being pressed below
glfwEnable( GLFW_STICKY_KEYS );
do{
// Draw nothing
// 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 ) );
问题是 MinGW 不太喜欢这个并且已经产生了大量的 “未声明”错误,所有这些都是 OpenGL 窗口存在所必需的。除了一点点 SDL2 之外,我从未使用过任何图形库,因此您可能需要引导我完成这个……非常感谢。

最佳答案
您使用 GLFW3
header ,但您编写的代码适用于 GLFW2
。
在 GLFW3
中,函数 glfwOpenWindowHint()
被重命名为 glfwWindowHint()
查看此页面以获取升级说明:http://www.glfw.org/docs/3.0/moving.html自 GLFW2
以来,发生了很多变化。
关于c++ - glfwOpenWindowHint 未在此范围内声明 GLFW3 和 GLEW,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/18363093/
