Error in compilation

[Ehsanizadi]

Hey,

I am very new to Bullet (a few hours!, version 2.82), linux (I am using Ubuntu 13.10) and programming!
I just installed Bullet physics on my ubuntu.

I tried to compile the Helloworld example using this command in the shell:

Code: Select all

g++ *.cpp -lSDL -lGL -lGLU -lSDL_image -lBulletSoftBody -lBulletDynamics -lBulletCollision -lLinearMath -I/usr/include/bullet/

but I get this error:

Code: Select all

/usr/bin/ld: cannot find -lSDL
/usr/bin/ld: cannot find -lSDL_image
collect2: error: ld returned 1 exit status

Any suggestion? Ideas?

Thank you in advance
Ehsan

This isn't really a Bullet build issue, but a dependencies problem. You're trying to link the SDL and SDL_image libraries, but they don't exist on your machine.
Find the library files for SDL and place them within your library directories and it should link correctly.

I installed the libraries now I get another error:

Bullet doesn't use SDL. You forgot to add the OpenGLSupport library.

You better use a build system that ships with Bullet, such as premake or cmake. It should compile out-of-the-box. See the instructions in the docs folder.

How to add OpenGLSupport library in the command I should type? (where should it be written?) If possible, could you please write the whole command should be typed in shell to run a code?
PS: I used Cmake to install bullet.
