[Freeciv-Dev] Freeciv on Pocket PC

[Christian Prochaska <cp.ml.freeciv.dev@xxxxxxxxxxxxxx>]

Hi, I've successfully compiled Freeciv for my StrongARM Pocket PC using
Mamaichs port of GCC for the ARM CPU platform (Cygwin version):

http://web.archive.org/web/20041115041606/mamaich.kasone.com/fr_pocket.htm

There is no HOWTO yet, but if you want to try yourself you can get my
complete development environment at

http://web.inf.tu-dresden.de/~s3564543/freeciv-sdl/freeciv-ppc/freeciv-ppc-2005-11-27-dev.7z

or if you just want to play you can download binaries of the game here:

http://web.inf.tu-dresden.de/~s3564543/freeciv-sdl/freeciv-ppc/freeciv-ppc-2005-11-27-bin.zip

(These links will probably change in time, because I don't have enough
webspace to keep more than one version, so if the links don't work
anymore please browse
http://web.inf.tu-dresden.de/~s3564543/freeciv-sdl/ for newer versions)

The archive was compressed using 7zip (http://www.7-zip.org/) and you
should extract it directly to C:\

To build the included Freeciv snapshot just do the following steps:

1.) run C:\freeciv-ppc\msys\1.0\msys.bat
2.) $ cd /c/freeciv-ppc/src
3.) $ ./build_freeciv.sh

If everything goes well you'll find civserver.exe, civclient.exe and the
data directory installed to C:\freeciv-ppc\bin

Then copy these files + the data directory + libc.dll + sdlgcc.dll to
some folder on your Pocket PC and install PocketConsole
(http://www.symbolictools.de/public/pocketconsole/) and PocketCmd
(http://www.symbolictools.de/public/pocketconsole/applications/PocketCMD/index.htm)

If your version of Windows Mobile does not support screen rotation
you'll also need a tool like nyditot (http://www.nyditot.com).

To play the game, switch the display to landscape mode, then run
PocketCmd, then "cd" to the folder where civserver.exe and civclient.exe
are stored and enter "civserver -l logs.txt". Then finally start another
instance of PocketCmd, "cd" to your game folder again and enter
"civclient -l logc.txt -t trident".

If it doesn't work maybe there's not enough free memory available
(server and client together need about 50 MB with trident tileset at
this time, even more with isometric tilesets :-|). Then you could try to
deinstall some of your other software or delete some unused tilesets
from the data directory. Please check the logfiles (logs.txt and
logc.txt), too. (btw. don't run server or client without the -l
parameter, because that will probably make them crash). Finally you
could also delete civserver.exe and start a server on your Windows
machine (for example /c/freeciv-ppc/bin/civserver-mingw32.exe) which
would save some megs of RAM, too. The hostname at the connection dialog
would then have to be the hostname of your windows machine (ah, and
don't forget to enable network routing in the ActiveSync application).

Attached to this mail are the patches that were applied to the Freeciv
source tree. I don't know if they are correct for other arm-wince-pe
compilers too, because I didn't get those other compilers to work yet.
Also, the "freeciv-config-2005-11-27.diff" patch is very ugly because it
changes config.h and a  Makefile, but I don't know how to add the
arm-wince-pe target and the corresponding detection fixes to the right
files. And there's another problem I didn't find a good solution for so
far: tolua.exe is needed during the compilation process, but since I'm
cross-compiling, tolua.exe is built for the target platform and doesn't
run on the Windows host. I temporarely "solved" this by copying
tolua.exe from a Mingw32 compilation to the dependencies/tolua directory
and changing the file extension for the autogenerated file to .exe2, but
of course their should be found another way.

So that's all for now. If you're going to try it, I wish you good luck! :-)

Christian
