Can not get SDL display to work with python example.

[bmburkhardt]

Hi, I'm having issues getting the SDL display to work for the python implementation. I feel I've followed steps correctly by looking at the original docs as well as a few solved solutions but I'm still not having any luck. Here is what I have done:

1. Running Ubuntu 16.04
2. sudo apt-get install libsdl1.2-dev libsdl-gfx1.2-dev libsdl-image1.2-dev cmake
3. added -DUSE_SDL=ON to the cmake args in setup.py
4. ran "pip install ."
5. changed "USE_SDL = False" to "USE_SDL = True" in python_example.py
6. python doc/examples/python_example.py roms/classic_kong.smc snes
7. Output:

   ('Episode', 3, 'ended with score:', 1900)
   ('Episode', 4, 'ended with score:', 800)
   ('Episode', 5, 'ended with score:', 100)

   ('Episode', 7, 'ended with score:', 900)
   ('Episode', 8, 'ended with score:', 400)
   ('Episode', 9, 'ended with score:', 100)

It runs just fine, however, there is no graphical display.

Compile the shared library interface following the instructions in the README.md. Then, the easiest way to solve this, is to copy the 'snes9x2010_libretro.so' file into the folder 'rle_python_interface'.
