Subject: SDL Patch

Hio,

I saw your last call on the mailing list. Here's a patch which I
submitted about two weeks ago which hasn't made it in.

In the current sdl.m4, there's a bug where if your configure.ac, you
have AC_LANG(C++) specified, it won't properly compile and link the SDL
test program when you run the configure script. This is because only the
default CFLAGS is overriden in sdl.m4, and in the patch below, I've
fixed it so it overrides CXXFLAGS as well, allowing it to work with g++.

PicoGUI is a scalable GUI system with a unique architecture, primarily focused
slouken@433
     8
on scalability to various embedded systems. You can find more information
slouken@433
     9
including a FAQ at http://picogui.org

To use the patch:
slouken@433
    12
slouken@433
    13
  1. When compiling, add the "--enable-video-picogui" switch to ./configure
slouken@433
    14
slouken@433
    15
  2. When running your program, ensure that the picogui driver for SDL
slouken@433
    16
     is in use by setting the SDL_VIDEODRIVER environment variable 
slouken@433
    17
     to "picogui".

  3. The program must also be linked to the C client library for PicoGUI
slouken@433
    20
     (libpgui.so). If the program is being compiled with a patched SDL 
slouken@433
    21
     installed this should be done automatically. If you want to use an
slouken@433
    22
     existing binary with PicoGUI, you can set the LD_PRELOAD environment
slouken@433
    23
     variable to the path of your libpgui.so file.

  So far only basic functionality is provided on true color (linear16/24/32)
slouken@433
    28
  devices. Accessing a memory mapped bitmap, updating the display, and handling
slouken@433
    29
  mouse/keyboard input. This functionality has been tested with several
slouken@433
    30
  applications, including mplayer, Xine, sldroids, and Abuse.

TODO list:
slouken@433
    33
slouken@433
    34
  - YUV overlays will be helpful for watching video on set top boxes or other
slouken@433
    35
    embedded devices that have some graphics acceleration hardware
slouken@433
    36
slouken@433
    37
  - Account for rotated bitmap storage in pgserver
slouken@433
    38
slouken@433
    39
  - Support for hiding or changing the cursor
slouken@433
    40
slouken@433
    41
  - The display should be centered when the SDL application is smaller
slouken@433
    42
    than the PicoGUI panel
slouken@433
    43
slouken@433
    44
  - Fullscreen or any other special modes
slouken@433
    45
slouken@433
    46
  - Support for indexed and grayscale modes
slouken@433
    47

    48
  - Probably much more...
