With some fiddling I managed to get the RLX code running under OSX. &nbsp;Some of the RLX related packages got patched out thanks to dto&#39;s fast response, the only hurdle was the lispbuilder libraries.<div><br></div><div>Step by step guide for sbcl:</div>
<div><br></div><div>i) Get the SDL and SDL_image frameworks from their respective sites:</div><div><a href="http://www.libsdl.org/release/SDL-1.2.13.dmg">SDL-1.2.13.dmg</a><br></div><div><a href="http://www.libsdl.org/projects/SDL_image/release/SDL_image-1.2.7.dmg">SDL_image-1.2.7.dmg</a><br>
</div><div>These should install under /Library/Frameworks/, there should be 2 new directories there called&nbsp;SDL.framework and SDL_image.framework.</div><div><br></div><div>ii) get &amp; load asdf-install</div><div>&gt; (require &#39;asdf-install)</div>
<div><br></div><div>iii) install lispbuilder-sdl, lispbuilder-sdl-image and cocoahelper</div><div>&gt; (asdf-install cocoahelper lispbuilder-sdl lispbuilder-sdl-image)</div><div><br></div><div>iv) At this point lispbuilder-sdl-image should complain that it cannot load the SDL_image framework. &nbsp;Open up the file in ~/.sbcl/site/lispbuilder-sdl-image/cffi/library.lisp and make sure the darwin line is the following:</div>
<div><div>&nbsp;&nbsp;(:darwin (:framework &quot;SDL_image&quot;))</div><div><br></div><div>iv) Retry compiling the lispbuilder-sdl-image and it should work this time:</div><div>&gt; (asdf:oos &#39;asdf:load-op &#39;lispbuilder-sdl-image)</div>
<div>&nbsp;Pull (or clone) the latest version of RLX from the git repository, as instructed in the installation guide.</div><div><br></div><div>v) Always make sure cocoahelper is loaded before you run RLX! &nbsp;It might be a good idea to add a (require &#39;cocoahelper) to rlx.lisp.</div>
<div><br></div><div>vi) Run the game as usual with:</div><div>&gt; (rlx:play &quot;vm0&quot;)&nbsp;</div><div><br></div><div><br></div><div><br></div></div>
