Recursive template math library

[REDDemon]

Does anyone know a zlib licensed recursive template math library? Armadillo is good but is LGPL..

[hendu]

Oh noes, you will have to supply source for Armadillo if you change it

(seriously, I don't get the LGPL hate)

@hendu: The problem with lgpl when working in the game-industry is that there are many platforms where you can't link dynamically (all consoles). So to use lpgl there you would also have to deliver your game-sources.

[REDDemon]

and you can't put templates in dlls since are only in headers. anyway I need zlib licensed code because I'm doing a project wich is licensed zlib and wanna use only zlib code. If I start putting different licenses than I must warn users, make a bigger license and definitively make users to go away from the project since they don't understand so many licenses etc.

Indeed, now that I took a closer look LGPL c++ templates are effectively GPL.

@CuteAlien

Sure, but I was only aware of Irrlicht running on the old Xbox, and iProducts?

[CuteAlien]

I think the the c++ standard libraries delivered on Linux have made some license exceptions to ensure you can still use those. Maybe Armadillo has the same.

And yeah - I don't know on how many platforms Irrlicht runs where lgpl is a problem for closed-source games (I don't develop for mobile phones so far - so no idea how the situation is there).

I tried creating some simple function on my own. That's much much interesting. Actually only few vector and matrix functions. there is gain only for complex expressions like (vec1*vec2)+vec3. If you need to do just (vec1=vec3) is faster (not too much) a non-templated inlined library. Templates are really a hell anyway O_O. I don't know If I'll finish that library afterall. at least that was a good learning session, but finishing will require lot of time that I don't have. still looking for a zlib licensed alternative.
