This all looks OK. There are two areas where things might go wrong:

1) 32 v 64 libraries. Make sure you're linking against appropriate libraries. Try linking with CPPVERBOSE=1:

  make CPPVERBOSE=1

2) Graphics card driver. Find out what your graphics card is and make sure you have installed the appropriate driver.

Incidentally, the "compound" command, "/vis/drawVolume" stands in for the scene and scenHandler commands above, so:

  /vis/open OGLIX
  /vis/drawVolume

should have the same effect.

And if you want to place your window, try

  /vis/open OGLIX 600x600-0+0
