I'm not sure if this helps anything, but it was clearly wrong.

     3 Using the Simple DirectMedia Layer with Qtopia/OPIE

     7 I.  Setting up the Qtopia development environment.
     8 
     9   This document will not explain how to setup the Qtopia development
    10   environment. That is outside the scope of the document. You can read
    11   more on this subject in this excellent howto:
    12 
    13 	http://www.zauruszone.com/howtos/linux_compiler_setup_howto.html
    14 
    15 ==============================================================================
    16 II.  Building the Simple DirectMedia Layer libraries using the arm
    17      cross-compiler
    18 
    19   This is somewhat tricky since the name of the compiler binaries
    20   differ from the standard. Also you should disable features not
    21   needed. The command below works for me. Note that it's all one
    22   line. You can also set the NM, LD etc environment variables
    23   separately.
    24 
    25 	NM=arm-linux-nm LD=arm-linux-ld CC=arm-linux-gcc CXX=arm-linux-g++ RANLIB=arm-linux-ranlib AR=arm-linux-ar ./configure --enable-video-qtopia --disable-video-dummy --disable-video-fbcon  --disable-video-dga --disable-arts --disable-esd --disable-alsa --disable-cdrom --disable-video-x11 --disable-nasm --prefix=/opt/Qtopia/sharp/ arm-unknown-linux-gnu
    26 
    27   One thing to note is that the above configure will include joystick
    28   support, even though you can't have joysticks on the Zaurus. The
    29   reason for this is to avoid link / compile / runtime errors with
    30   applications that have joystick support.
    31 
    32 ==============================================================================
    33 III.  Building the Simple DirectMedia Layer test programs:
    34 
    35   After installing, making sure the correct sdl-config is in your
    36   path, run configure like this:
    37 
    38 	NM=arm-linux-nm LD=arm-linux-ld CC=arm-linux-gcc CXX=arm-linux-g++ AR=arm-linux-ar ./configure arm-unknown-linux-gnu
    39 
    40 ==============================================================================
    41 IV.  Application porting notes
    42 
    43   One thing I have noticed is that applications sometimes don't exit
    44   correctly. Their icon remains in the taskbar and they tend to
    45   relaunch themselves automatically. I believe this problem doesn't
    46   occur if you exit your application using the exit() method. However,
    47   if you end main() with 'return 0;' or so, this seems to happen.
    48 
    49   Also note that when running in landscape mode - i.e requesting a
    50   window that is HEIGHT pixels wide and WIDTH pixels high, where WIDTH
    51   and HEIGHT normally is 240 and 320 - the image is blitted so that
    52   the hardware buttons are on the left side of the display. This might
    53   not always be desirable but such is the code today.
    54 
    55 
    56 ==============================================================================
    57 V.  Enjoy! :)
    58 
    59   If you have a project you'd like me to know about, or want to ask questions,
    60   go ahead and join the SDL developer's mailing list by sending e-mail to:
    61 
    62 	sdl-request@libsdl.org
    63 
    64   and put "subscribe" into the subject of the message. Or alternatively you
    65   can use the web interface:
    66 
    67 	http://www.libsdl.org/mailman/listinfo/sdl
    68   
    69 ==============================================================================
    70 VI.  What is supported:
    71 
    72 Keyboard (Sharp Zaurus)
    73 Hardware buttons
    74 Stylus input (mouse)
    75 Video. Allows fullscreen both in portrait mode (up to WIDTHxHEIGHT
    76 size window) and in landscape mode (up to HEIGHTxWIDTH). 
    77 
    78 All other SDL functionality works like a normal Linux system (threads,
    79 audio etc).
