OpenGL glGenLists返回 0 为什么呢

小弟学习Opengl 要绘制三角网格的面和每个面的边因为我每次调用面的材质和边的材质设置计算会很慢
想优化一下所以使用 list 但是 glGenLists返回 0。而0 是说明没有成功执行list的生成。帮我看看吧可能就是个小地方没有想到谢谢了
// 有色面
void COpenGLView::SetFaceMaterial()
{

GLfloat material_Ka[] = {0.11,1.0,0,11,1.00};
GLfloat material_Kd[] = {0.43,1.0,0.54,1.00};
GLfloat material_Ks[] = {0.33,1.0,0.54,1.00};
GLfloat material_Ke[] = {0.00,0.0,0.00,1.00};
GLfloat material_Se[] = {10.0};

glMaterialfv(GL_FRONT,GL_AMBIENT,material_Ka);
glMaterialfv(GL_FRONT,GL_DIFFUSE,material_Kd);
glMaterialfv(GL_FRONT,GL_SPECULAR,material_Ks);
glMaterialfv(GL_FRONT,GL_EMISSION,material_Ke);
glMaterialfv(GL_FRONT,GL_SHININESS,material_Se);
}
// 设置边框线的材质黑线
void COpenGLView::SetLineMaterial()
{
GLfloat material_Ka[] = {0.0f,0.0f,0.0f,1.0};
GLfloat material_Kd[] = {0.0f,0.0f,0.0f,1.0};
GLfloat material_Ks[] = {0.0f,0.0f,0.0f,1.0};
GLfloat material_Ke[] = {0.0f,0.0f,0.0f,1.0};
GLfloat material_Se[] = {10.0};

glMaterialfv(GL_FRONT,GL_AMBIENT,material_Ka);
glMaterialfv(GL_FRONT,GL_DIFFUSE,material_Kd);
glMaterialfv(GL_FRONT,GL_SPECULAR,material_Ks);
glMaterialfv(GL_FRONT,GL_EMISSION,material_Ke);
glMaterialfv(GL_FRONT,GL_SHININESS,material_Se);

}

int COpenGLView::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CView::OnCreate(lpCreateStruct) == -1)
return -1;
m_selected =false; //文件还没有选取
// 将线纹理的处理保存在 list里
m_list_line = glGenLists(1);
glNewList(m_list_line,GL_COMPILE);
SetLineMaterial();
glEndList();

// 将面的处理放在 list中
m_list_face = glGenLists(1);
glNewList(m_list_face,GL_COMPILE);
SetFaceMaterial();
glEndList();
InitializeOpenGL();
return 0;
}
