Subject: Patch to put back dynamic OpenGL loading for MPW

I sent a patch a while ago that removes dynamic OpenGL loading for
Macintosh Programmer's Workshop. Dynamic loading DOES actually work
when an SDL program is built with MPW, it just has to be set up for it.
(Whoops!!) This is the ideal way to get OpenGL extensions to work,
which D2X uses quite a few of.

This patch puts dynamic loading back in SDL for Mac OS 9. It applies to
current CVS. I noticed that two members need to be set when
DrawSprocket is used.

I.  Setting up the Qtopia development environment.

  This document will not explain how to setup the Qtopia development
slouken@386
    10
  environment. That is outside the scope of the document. You can read
slouken@386
    11
  more on this subject in this excellent howto:

II.  Building the Simple DirectMedia Layer libraries using the arm
slouken@386
    17
     cross-compiler
slouken@386
    18
slouken@386
    19
  This is somewhat tricky since the name of the compiler binaries
slouken@386
    20
  differ from the standard. Also you should disable features not
slouken@386
    21
  needed. The command below works for me. Note that it's all one
slouken@386
    22
  line. You can also set the NM, LD etc environment variables
slouken@386
    23
  separately.

  One thing to note is that the above configure will include joystick
slouken@386
    28
  support, even though you can't have joysticks on the Zaurus. The
slouken@386
    29
  reason for this is to avoid link / compile / runtime errors with
slouken@386
    30
  applications that have joystick support.

    35
  After installing, making sure the correct sdl-config is in your
slouken@386
    36
  path, run configure like this:
slouken@386
    37
slouken@386
    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

IV.  Application porting notes
slouken@386
    42
slouken@386
    43
  One thing I have noticed is that applications sometimes don't exit
slouken@386
    44
  correctly. Their icon remains in the taskbar and they tend to
slouken@386
    45
  relaunch themselves automatically. I believe this problem doesn't
slouken@386
    46
  occur if you exit your application using the exit() method. However,
slouken@386
    47
  if you end main() with 'return 0;' or so, this seems to happen.
slouken@386
    48
slouken@386
    49
  Also note that when running in landscape mode - i.e requesting a
slouken@386
    50
  window that is HEIGHT pixels wide and WIDTH pixels high, where WIDTH
slouken@386
    51
  and HEIGHT normally is 240 and 320 - the image is blitted so that
slouken@386
    52
  the hardware buttons are on the left side of the display. This might
slouken@386
    53
  not always be desirable but such is the code today.

  If you have a project you'd like me to know about, or want to ask questions,
slouken@386
    60
  go ahead and join the SDL developer's mailing list by sending e-mail to:
slouken@386
    61
slouken@386
    62
	sdl-request@libsdl.org
slouken@386
    63
slouken@386
    64
  and put "subscribe" into the subject of the message. Or alternatively you
slouken@386
    65
  can use the web interface:

VI.  What is supported:
slouken@386
    71
slouken@386
    72
Keyboard (Sharp Zaurus)
slouken@386
    73
Hardware buttons
slouken@386
    74
Stylus input (mouse)
slouken@386
    75
Video. Allows fullscreen both in portrait mode (up to WIDTHxHEIGHT
slouken@386
    76
size window) and in landscape mode (up to HEIGHTxWIDTH). 
slouken@386
    77
slouken@386
    78
All other SDL functionality works like a normal Linux system (threads,
slouken@386
    79
audio etc).
