Re: [XBoard-devel] XBoard

[Tim Mann]

I am involved in the project but personally am not actively working on it.

I don't know if you "have to" use XBoard on a Mac. I am not a Mac user and don't know if there are other options for a chess GUI on Mac. I have no idea how well XBoard works on Mac currently.

Your program does not have to be open source to work with XBoard.  Chess engines interact with XBoard over a pipe or network connection. They don't even dynamically link with it, much less statically link. So the GPL does not require an engine that works with XBoard to be open source.

Hi Tim. I understand you are involved with XBoard. I have been developing a chess engine over the last couple of years in XCode on a Mac. Its finally reached the point where I need to test it against other engines. Apparently if im using a Mac then I pretty much have to use XBoard. Is this true? And if so I just have a quick question. Is XBoard only for open source programs? Meaning you can only connect your program if you are willing to have others see your source code? I will be working on some techniques that may not be used by other programs currently and if succesfull I’d like to keep them proprietary for a period while I further test them. And finally, is XBoard working well for Mac users? I’ve seen some old threads regarding difficulties with XBoard and OSX. Not sure if they have been resolved. Thanks in advance.
