problem with HelloWorld

[MateuszEs]

Hi. I want to learn Bullet, but there is only one tutorial for beginners - Helloworld - which doesn't work. Please give me some adviese how can I run HelloWorld, or let me know if there are other tutorials for Bullet.

I understand each line in HelloWorld but I have no idea what to do next. How can I render this example. Could someone help me?
