I'm thinking that using cl-opengl, rather than making another OpenGL wrapper, is definitively a good idea. The more standard, the better, right?
Although I wonder if cl-opengl can be used as is. Android and iOS use OpenGL ES, which is a subset of the normal OpenGL.
Maybe the maintainers of cl-opengl might be able of offer more insight on this? I myself am not particularly an expert on cl-opengl internals. At any rate, the mailing list for that is:
http://common-lisp.net/cgi-bin/mailman/listinfo/cl-opengl-devel
I'll try to adapt cl-opengl into cl-opengles1 on the weekend. Let's
see how far I can go.
I'll let you know.

@Joop: thanks! I'll read into CC0 :)
@Elliot: whether or not to use cl-OpenGL is an undecided matter. Right now, just for testing, I wrote a pair of function wrappers. If you would like to add cl-OpenGL to the project, you are more than welcome!
Thanks for your replies!

When you talk about making a wrapper around OpenGL, are you using
cl-opengl?
I already use cl-opengl in my game engine, so if you did that would encourage me to think about supporting Android. Otherwise (if you are writing your own wrapper) I would probably be discouraged from
attempting to
port my engine. Thanks. On Sat, Jun 18, 2011 at 7:40 PM, Simon Ortiz o.simon@gmail.com wrote:
dear Lispers and dear game-devs,
I'm working on a project to make games on Lisp for smartphones.
I'm writing to let you all know of this project. If someone is interested, please let me know, so we can advance the project faster and make better code.
The project works using ECL, which has being ported to Android and iOS thanks to the work of Ram Krishnan and Sylvain Ageneau. Right now, you can start ECL on these devices, load and execute any Lisp code. As an example, which is included in the project, you can run a Swank server on the devices, and connect to it from Slime.
I'm starting from those projects and I'm attempting to make the connections necessary for making games. My first target is Android. Right now, Lisp can communicate with OpenGL (but there are some crashes...), and Java can communicate touch events to Lisp.
The first goal is to be able to draw OpenGL primitives (without crashing), draw textures, and output sound. The second goal is to build the same connections for iOS. The third goal, for the remote future, is to have internet connections. And the fourth goal, for an even farther future, is to read gyroscopes data and GPS data.
This project is not aiming at making a Lisp game engine. That is left as an exercise for the developer. But with all the connections there, making your game/engine should be easier.
Also, since this project is aiming at releasing games through the App Store, it cannot contain any GPL software. All my work is on the public domain (as in "yes, you can go, use it, make money, and never tell me"). ECL is released under the LGPL license, so there should be no problems if you fulfill your responsibilities.
If you want to check the (still crashing) project go to:
https://github.com/o-simon/ecl-smartphones
If you want to collaborate, please send me an email. I'll give you write access to the repository.
I hope to hear from you soon.
Sincerely,
