XCSoar will run on Android by next year. It already runs on desktop

Linux/Android will be the primary target operating system for ,
because Windows Mobile 7 does not allow running XCSoar (or any other
existing software). It is not compatible with prior versions.

Max,

How do you define 'not well'? Have you actually hand-ported it, or are
you using wine/winelib with the win32 version? Does it only work on x86?
Any showstopper bugs? Do you want testers? Where is the code - in a GIT
repo somewhere?

I ask this because I have a Nokia N900 in my pocket right now, and was
kinda wondering if it would compile/run on that. Specs a

Debian-based 2.6.xx linux (Can run straight Debian/Ubuntu ARM
edition/Android too)
800mhz OMAP3/ArmCortexA8
800x480 *TRANSFLECTIVE* LCD (Readable in direct sunlight)
OpenGLES 1.0/1.1/2.0
256mb DDR2 ram
32GB Flash
GPS
serial ports
bluetooth
etc etc.

I have a bit experience with hacking linux on embedded devices,
especially trying to shoehorn Debian/Ubuntu onto anything i can get my
hands on, but passionately hate having to code in C/C++ if i can at all
avoid it. I have already been tempted to try a compile of the Win32
version of XCSoar with WINElib anyway, but if there is a genuine Linux
port underway, i would like to help in any (reasonable) way I can. The
same goes for Paulo & his LK8000 SW too.

Thanks,

Mike

Hi Mike,

we have hand-ported it ("the right way"), by writing an OO abstraction
layer for GDI calls, and incrementally writing a port based on SDL /
SDL_gfx. There shall be another backend for OpenGL.

"Not well" because it's slow and flickers: no double buffering; child
windows are emulated by creating an internal SDL_Surface, and copying
these over and over. Too much overhead for any embedded device, and
SDL_gfx does not use hardware acceleration. The first goal was
reached: to make it run with a native Linux binary. Optimization
comes next.

You can get the most current sources from my git repository:

git clone git://git.snow-crash.org/xcsoar.git
http://max.kellermann.name/projects/xcsoar/

Have fun hacking it! And remember to submit patches back to us.

Max

The answer is... do a native port with Android. Software running on
Windows Mobile and Windows CE badly needs to die, it just a crap
platform from the last century. [..]

Amen!
