How to apply texture to glutSolidCube

I can find tutorials about mapping textures to polygons specifying vertices etc. but nothing regarding how to apply a texture to a cube (or other stuff) drawn with glut (glutSolidCube).

I am doing something like:

glTexEnvfv(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, decal);
glTexParameterfv(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, repeat);
glTexParameterfv(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, repeat);
glTexParameterfv(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, nearest);
glTexParameterfv(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, nearest);

glPixelStorei(GL_UNPACK_ALIGNMENT, 1);
glTexImage2D(GL_TEXTURE_2D, 0, 4, myImageWidth, myImageHeight, 0, GL_RGBA, GL_UNSIGNED_BYTE, (GLvoid *)myImage);

//...

glEnable(GL_TEXTURE_2D);

//now draw the cube
glutSolidCube(N);

Doing this I get the texture to apply to the cube but the whole cube gets the color of the first byte in the texture!

Is there any way of mapping a texture to a solid cube (and other solids) when using glutSolidCube?

Actually there is one solution...

you can use generate texture co-ordinates like this

    glEnable(GL_TEXTURE_GEN_S); //enable texture coordinate generation
    glEnable(GL_TEXTURE_GEN_T);
    glBindTexture(GL_TEXTURE_2D, theTexture[2]);
    glutSolidCube(2);
    glDisable(GL_TEXTURE_GEN_S); //enable texture coordinate generation
    glDisable(GL_TEXTURE_GEN_T);

No, since glutSolidCube() does not generate texture coordinates. Fortunately, though, glutSolidCube() is easy to implement yourself and add texture coordinates. Here's the source code to glutSolidCube() and associated functions, from http://www.opengl.org/resources/libraries/glut/:

Just add in some calls to the glTexCoord* family of functions. NeHe has a good tutorial on how to get started with texture mapping with OpenGL.

According to the GLUT API documentation:

[glutSolidCube generates] normals appropriate for lighting but do not generate texture coordinates (except for the teapot).
