Question

我目前正试图用GLFW和GLEW绘制一个简单的三角形。

我在Win 8.1 x64 PC上使用CLion（它本身使用cmake和cygwin）。

我的问题是：glewInit()在初始化时返回错误1（Missing GL version）。人们（比如在this线程中）遇到了与OpenGL上下文相关的问题，但是在我调用glewInit()之前已经创建了我的。

这是我的代码：

#include <iostream>
#include <stdlib.h>
#include <vector>

#define GLEW_STATIC

#include <GL/glew.h>
#include <GLFW/glfw3.h>
#include <glm/glm.hpp>

//...

if(!glfwInit()) {
    std::cerr << "Couldn't initialize GLFW" << std::endl;
}

glfwSetErrorCallback(glfw_error_callback);
glfwWindowHint(GLFW_SAMPLES, 4); //16x antialiasing sisi rpz
glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3); // OpenGL 3.3
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);

window = glfwCreateWindow(width, height, title.c_str(), NULL, NULL);
if(window == NULL) {
    std::cerr << "Failed to open GLFW window. Are your drivers up-to-date ?" << std::endl;
    glfwTerminate();

    exit(EXIT_FAILURE);
}


glfwMakeContextCurrent(window);
if(!glfwGetCurrentContext()) {
    std::cerr << "Couldn't create OpenGL context" << std::endl;
    exit(EXIT_FAILURE);
}

glewExperimental = GL_TRUE;
GLenum err = glewInit();
if(err != GLEW_OK) {
    std::cerr << "Failed to initialize glew : " << glewGetErrorString(err) << " (" << err << ")" << std::endl;
}

和我的CMakeLists.txt：

cmake_minimum_required(VERSION 2.8.4)
project(MY_PROJECT)

set(SOURCE_FILES main.cpp Host.cpp GraphicWindow.cpp)
add_executable(MY_PROJECT ${SOURCE_FILES})

target_link_libraries(MY_PROJECT wsock32 ws2_32)

#GL stuff
include_directories(lib/glew-1.11.0/include/)
include_directories(lib/glfw-3.0.4.bin.WIN64/include/)
include_directories(lib/glm)

target_link_libraries(MY_PROJECT glfw3 glu32 gdi32 opengl32 glew)

Glew初始化失败：缺少GL版本（GLFW）
