Xboard GTK for Windows

[Josh Pettus]

I've been thinking about trying this for a while. In theory rather then have 2 separate code bases we could just use xboardGTK instead as GTK2 is available for windows as well. This has a few advantages
1. Easier to maintain
2. Librsvg/cairo is much more advanced then win32's rendering:
- SVG images on top of looking cleaner are much more practical and easier to create then chess fonts. (Inkscape is free and does a great job converting raster images to vector. Proper font software can cost hundreds of dollars )
-Resizable png images over the cumbersome bitmaps for every size cannot be overstated.
-Board Scalable to any size, not just fixed ones.

Fact is after using Xboard on OSX for years, Winbord just looks ugly

We would have to figure out the bundling later. Perhaps to some relative directory system: But it should be more then possible.
Step 1 though is to try to get it to compile.

Anyway I installed the mingw/msys package over here (mingw is a version of GCC modified to make native windows binaries)
http://www.mingw.org/
and downloaded the mingw GTK+ package here, and merged the folder into the mingw root folder:
http://sourceforge.net/projects/gtk-min ... s/gtk%2B2/
and did the same for mingw librsvg package here:
http://sourceforge.net/projects/gtk-min ... s/librsvg/

By default MSYS root folder is separate from the MinGW folder. This is cumbersome and I found it much easier to take the contents of ./MSYS/1.0/ folder to the root folder of MinGW, then deal with finding the libraries.

autogen.sh ran fine (I first tried it with a development build and got the same issue)
configure ran fine:

Leaves me scratching my head. Must be some MinGW quirk as there is no line 0 in backend.c or any file. Does anyone have any ideas?

[H.G.Muller]

It says <command-line>, which would make me think it is actually complaining against the way the Makefile invoked the compiler (like a syntax error in a -D option for defining a macro).

The idea to use XBoard on Windows too has come up before, but what stopped me is that it seemed to require installing hundreds of MB of non-standard libraries. I want to distribute packages that run 'out-of-the-box', and it would be pretty annoying if every bundle of engine + GUI I host would have to be >100MB instead of the ~700KB it is with winboard.exe in it. So I did not want to abandon the dedicated Windows front end. (Although I agree that XBoard graphics by now looks much better.)

But that should of course not stop people that do want to go through the trouble of installing the required infra-structure to use XBoard on Windows. Cygwin is supposed to be able to compile and run XBoard, and I think I actually tried that once (but that was before we had a GTK version). That was not a MinGW compile, though, but was using the Cygwin infra-structure (cygwin1.dll and such).

From the list of warnings I get the impression there is an incompatibility with the way of representing int64 arguments in printf() format strings. This has always been a problem in MinGW compiles, as gcc expects you to use %lld, while the library routines of the Windows API expect %I64d, where gcc again takes %I to mean something entirely different. So the way gcc matches the argument with the format (solely for the purpose of checking and issuing warnings) is different from what actually happens at run time. (When you linked to the Windows API.) And the code is written to assume linking to the Windows API when the macro WIN32 is defined.

I'll take a look at those compile options.

The OSX app is bundled with all the non standard libraries and it's only 27Mb (19Mb of which is the libraries themselves). I don't think that's too large, especially this day and age. All the other chess GUI's are much larger.

We would have to think about the bundling though, and how xboard accesses its resources to make it portable. (kinda like we do with the mac version only without the benefit of the integration library.) We also have to figure out what we actually need for runtime. I'll poke at it with a stick for now, see if it moves.

On the other hand GTK really is a PIA, so I really don't blame you....
