Hallo
I have build VampyreImaging.so on Ubuntu 14.04

I try to compile this  part of the tutorial http://wiki.lazarus.freepascal.org/OpenGL_Tutorial#Textures
and there is in the texture.lpr this line
uses
  gl, glu, glut, ImagingOpenGL;

• Where should I place this file?


• Should I rename VampyreImaging.so to ImagingOpenGL?

The error I got is
textures.lpr(6,18) Fatal: Can not find unit ImagingOpenGL used by textures.

Please, help me.
I use Lazarus 1.2.2 with fpc 2.6.4 on Ubuntu 14.04
