Here's a quick guide to getting you started with Experi.

Let's start by downloading the latest version at:
https://sourceforge.net/projects/experi/

If you have Subversion installed, simply run:
svn co https://experi.svn.sourceforge.net/svnroot/experi experi

In the experi directory, run:
cmake .

Assuming everything goes fine, you should see the following three lines at the end:
-- Configuring done
-- Generating done
-- Build files have been written to: /home/jfbilodeau/tmp/experi

If you get a 'command not found' with cmake, there's a good chance that CMake is not install. Otherwise, any other errors are most likely due to missing or misconfigured libraries. You will need OpenGL (or Mesa on Linux), libSDL and libSDL-Image. Finally, make sure that you have gcc (or another compiler) installed on your machine.

Next, run make:
make

The last line printed should be similar to:
[100%] Built target interactive

If that's the case, go ahead and try to run the demos under /demo/*. For example:
cd demo/helloworld3d
./helloworld3d

You should see a rotating square. If that's the case, rejoice! You're in business! Start hacking away at the examples, or attempt to create your own project.

Enjoy!
