OpenGL: glGetError() returns invalid enum after call to glewInit()
- by malymato
I use GLEW and freeglut. For some reason, after a call to glewInit(), glGetError() returns error code 1280. Reinstalling the drivers didn't help. I tried to disable glewExperimental, it had no effect. Code worked before, but I am not aware of any changes I could possibly make.
Here's my code:
int main(int argc, char* argv[])
{
GLenum GlewInitResult, res;
InitWindow(argc, argv);
res = glGetError(); // res = 0
glewExperimental = GL_TRUE;
GlewInitResult = glewInit();
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 < 1)
{
fprintf(stderr, "ERROR: Could not create new rendering window.\n");
exit(EXIT_FAILURE);
}
glutReshapeFunc(ResizeFunction);
glutDisplayFunc(RenderFunction);
glutIdleFunc(IdleFunction);
glutTimerFunc(0, TimerFunction, 0);
glutCloseFunc(Cleanup);
glutKeyboardFunc(KeyboardFunction);
}
Could someone tell me what I am doing wrong? Thanks.
