opengl 3.3 and glTexImage2D

OpenGL OpenGL: Basic Coding

Hello,
according to the opengl 3.2 api quick reference card,
texture formats GL_LUMINANCEn have been removed. So
I set instead GL_INTENSITY. But when I call glTexImage2D
I get the error (1280 - INVALID_ENUM).

My settings are
glTexImage2D(GL_TEXTURE_2D, 0, GL_INTENSITY8, width,height,0, GL_INTENSITY, GL_UNSIGNED_BYTE, dataPtr);

So, where is the problem ?

regards,

GL_RED8 GL_R8,
GL_RED

thanks, it works.
But I wonder why GL_INTENSITY is not working.
It’s not marked as depricated or not supported.
