I'm integrating EASTL into my game programming framework. I did some changes to it since I have my own memory management sub-system and now I'm wondering what I need to do to not break the license under which EASTL was released.

Since I will probably be releasing the source code on GitHub at some point, but do not plan on releasing any binaries without source code, can I just add something similar to my own source files and be okay with this? Will something like the following do?

P.S. This is a repost of a legal-like question from StackOverflow where it was found off-topic. If this is off-topic here as well, please tell me where I can ask such question?

@maple_shaft Hi, Thanks. I did not know I can do that. –  Bartłomiej Siwek Apr 27 '12 at 18:57

Your own source files don't require that copyright notice. Your source files were written by you, not EA. What that provision is saying is that you are not to redistribute their source files without keeping their copyright/license block on them. (It's a basic attribution requirement.)

Similarly, when you distribute a binary, you have to distribute something with it that has the license block. I'd do it like "This product uses EASTL (https://github.com/paulhodge/EASTL), which is licensed under the following terms: <insert blurb here>".

+1, this is a very similar license agreement as the GPL, which also requires the license be distributed with their binaries in whatever software package you distribute or use. I would just make sure not to modify the souce code headers and include the license files within or next to the EA binaries. –  maple_shaft Apr 27 '12 at 18:16
    
Not sure if that stood out in the question enough - I actually modify their code/headers since I need to adapt them to my memory management subsystem and general way I like to code. So for example I want to use their code for a vector class but modify the memory allocation part etc. –  Bartłomiej Siwek Apr 27 '12 at 19:01
