我使用GLEW和freeglut.出于某种原因,在调用glewInit()之后,glGetError()返回错误代码1280,即使使用glewExperimental = GL_FALSE也是如此.

我无法编译着色器,glGetProgramInfoLog()返回"在调用glLinkProgram()之前未成功编译顶点着色器.链接失败." 之前我能够编译着色器.

重新安装驱动程序没有帮助.

这是我的代码:

int main(int argc, char* argv[])
{
    GLenum GlewInitResult, res;

    InitWindow(argc, argv);

    res = glGetError(); // res = 0

    glewExperimental = GL_TRUE;
    GlewInitResult = glewInit();    

    fprintf(stdout, "ERROR: %s\n", glewGetErrorString(GlewInitResult)); // "No error"
    res = glGetError(); // res = 1280

    glutMainLoop();

    exit(EXIT_SUCCESS);
}

void InitWindow(int argc, char* argv[])
{
    glutInit(&argc, argv);

    glutInitContextVersion(4, 0);
    glutInitContextFlags(GLUT_FORWARD_COMPATIBLE);
    glutInitContextProfile(GLUT_CORE_PROFILE);

    glutSetOption(GLUT_ACTION_ON_WINDOW_CLOSE,
    GLUT_ACTION_GLUTMAINLOOP_RETURNS);

    glutInitWindowPosition(0, 0);
    glutInitWindowSize(CurrentWidth, CurrentHeight);
    glutInitDisplayMode(GLUT_DEPTH | GLUT_DOUBLE | GLUT_RGBA);

    WindowHandle = glutCreateWindow(WINDOW_TITLE);

    GLenum errorCheckValue = glGetError();

    if (WindowHandle …
