Well I was looking at the .app file from castle of magic and guess what file I found inside: source.txt: source code of the Irrlicht Engine The complete source of the Irrlicht Engine can be found when decompressing the .zip file included in this directory. Please note that YOU DO NOT NEED THIS SOURCE to develop 3d applications with the Irrlicht Engine. Instead, please use the .dll in the \bin directory, the .lib in the \lib directory and the header files in the \include directory. why is the file in there and why aren;t gamelofts games open source lol
well just found this link: http://www.gameloftjobs.kiemviec.com/jobseeker/jobsearch/job_preview/71288/ lol they forgot they delete the irrlicht info file, shoudn;t they release the source as Irrlicht is open source?
Funny! Great to know. Anyhow I'm not a lawyer and don't know nothing relating this. In the link you posted they talk about Ogre engine.
Don't know about irrlicht, but here's the licensing FAQ for Ogre: LGPL FAQ. Basically, all they need to provide the source for is the OGRE engine itself. If they didn't modify the engine, then they just need to provide a link to the OGRE web page.
To be clear, the LGPL normally defaults to plain old GPL on the iPhone since Apple doesn't allow dynamic linking. The Ogre license provides an additional provision to specifically allow static linking, but folks really need to be careful when using LGPL'd code in their iPhone apps as they could easily be forced to hand over all their code.
Gameloft hasn't done anything wrong. Irrlicht engine's license is liberal and allows commercial use, linked whatever way. The only required attribution is that the original license isn't removed from the source code, but nothing there forces to distribute the source code. (as can be seen from the license which sam the lion already posted)
http://irrlicht.sourceforge.net/features.html: "The engine is open source and totally free. You can debug it, fix bugs and even change things you do not like. And you do not have to publish your changes: The engine is licensed under the zlib licence, not the GPL or the LGPL." Good to know that it can be made to work on iPhone... I'll have to check it out for my next game
