我遇到的问题是SDL表示它不支持OpenGL 3.x上下文.我正在尝试遵循本教程:在SDL(C/SDL)中创建跨平台OpenGL 3.2上下文.我在这种情况下使用GLEW,但我也无法使用gl3.h来处理这个问题.这是我最终得到的代码:

#include <glew.h>
#include <SDL.h>    

int Testing::init()
        {
            if(SDL_Init(SDL_INIT_EVERYTHING) < 0)
            {
                DEBUGLINE("Error initializing SDL.");
                printSDLError();
                system("pause");
                return 1; // Error
            }

            //Request OpenGL 3.2 context.
            SDL_GL_SetAttribute(SDL_GL_CONTEXT_MAJOR_VERSION, 3);
            SDL_GL_SetAttribute(SDL_GL_CONTEXT_MINOR_VERSION, 2);

            //set double buffer
            SDL_GL_SetAttribute(SDL_GL_DOUBLEBUFFER, 1);

            //Create window
            window = SDL_CreateWindow("OpenGL 3.2 test",
                SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED,
                600, 400, SDL_WINDOW_OPENGL | SDL_WINDOW_SHOWN);
            if(window == NULL) return 3; // Error

            //Print errors to console if there are any
            printSDLError(__LINE__);

            //Set up OpenGL context.
            glContext = SDL_GL_CreateContext(window);
            printSDLError(__LINE__);
            if(glContext == NULL) …
