glGenFramebuffers,glBindFramebuffer等未声明

Question

我正在尝试设置帧缓冲区对象,但我收到错误.glGenFramebuffers总是未声明的,像glBindFramebuffer这样的其他类似的事情也是如此.

我认为问题与导入有关,但我不确定如何解决这个问题.glew有可能无法正确设置,但我还没有找到如何完全设置它的简单解释.

这是失败的代码.

myBuffer = 0;
glGenFramebuffers(1, &myBuffer);
glBindFramebuffer(GL_FRAMEBUFFER, myBuffer); 


glGenTextures(1, &renderedTexture);

// Bind to new texture
glBindTexture(GL_TEXTURE_2D, renderedTexture);

// Blank image
glTexImage2D(GL_TEXTURE_2D, 0,GL_RGB, 1024, 768, 0,GL_RGB, GL_UNSIGNED_BYTE, 0);


glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST);


glGenRenderbuffers(1, &dBuffer);
glBindRenderbuffer(GL_RENDERBUFFER, dBuffer);
glRenderbufferStorage(GL_RENDERBUFFER, GL_DEPTH_COMPONENT, 1024, 768);
glFramebufferRenderbuffer(GL_FRAMEBUFFER, GL_DEPTH_ATTACHMENT, GL_RENDERBUFFER, dBuffer);



// Set "renderedTexture" as colour attachement #0
glFramebufferTexture(GL_FRAMEBUFFER, GL_COLOR_ATTACHMENT0, renderedTexture, 0);

DrawBuffers[2] = {GL_COLOR_ATTACHMENT0};

    glDrawBuffers(1, DrawBuffers); // "1" is the size of DrawBuffers
    // Check framebuffer is ok
      if(glCheckFramebufferStatus(GL_FRAMEBUFFER) != GL_FRAMEBUFFER_COMPLETE)
      return false;

你似乎已经正确地链接了glew32.lib,但我没有看到你实际上包括<GL/glew.h> 而不是 <GL/gl.h>.后者仅向OpenGL 1.1声明函数,而前者为所有扩展和核心功能提供声明> 1.1(如FBO).
