Simple OpenGL texture map not working?

Question

The polygon is being drawn, though it\'s not textured but just a soli

Answer 1

My OpenGL is rusty, but I remember having same problems with with glTexImage2D . Finally I managed to make it work, but I always had more luck with gluBuild2DMipmaps so i ended up with

gluBuild2DMipmaps (
  GL_TEXTURE_2D, type, i.width, i.height, type, GL_UNSIGNED_BYTE, i.data
);

which replaced

glTexImage2D (
  GL_TEXTURE_2D, 0, type, i.width, i.height, 0, type, GL_UNSIGNED_BYTE, i.data 
);
