compilation problem

[rodrigoml]

hello, I m starting with bullet, so I try to compile the basicdemo from bullet demos, after a successful compilation of the helloworld demo, and gave this:

as you see, I m using as static library the bullet and OpenGL (a folder from the bullet demos folder with a set of librarys that use this demo). It should work.. any suggestion?
thanks

You may not have linked glut in your compilation, try adding -lglut to your compilation line. Let me know by PM if it still fails.
If you check the errors, it is obvious that you are missing glut linkage.

If your system doesn't have glut: sudo apt-get install freeglut3-dev

---- edit

This is the generated cmake build line. You may want to investigate using cmake, it should have auto - built the demos for you.
