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++.

     7 PicoGUI is a scalable GUI system with a unique architecture, primarily focused
     8 on scalability to various embedded systems. You can find more information
     9 including a FAQ at http://picogui.org
    10 
    11 To use the patch:
    12 
    13   1. When compiling, add the "--enable-video-picogui" switch to ./configure
    14 
    15   2. When running your program, ensure that the picogui driver for SDL
    16      is in use by setting the SDL_VIDEODRIVER environment variable 
    17      to "picogui".
    18 
    19   3. The program must also be linked to the C client library for PicoGUI
    20      (libpgui.so). If the program is being compiled with a patched SDL 
    21      installed this should be done automatically. If you want to use an
    22      existing binary with PicoGUI, you can set the LD_PRELOAD environment
    23      variable to the path of your libpgui.so file.

    25 Capabilities:
    26 
    27   So far only basic functionality is provided on true color (linear16/24/32)
    28   devices. Accessing a memory mapped bitmap, updating the display, and handling
    29   mouse/keyboard input. This functionality has been tested with several
    30   applications, including mplayer, Xine, sldroids, and Abuse.
    31 
    32 TODO list:
    33 
    34   - YUV overlays will be helpful for watching video on set top boxes or other
    35     embedded devices that have some graphics acceleration hardware
    36 
    37   - Account for rotated bitmap storage in pgserver
    38 
    39   - Support for hiding or changing the cursor
    40 
    41   - The display should be centered when the SDL application is smaller
    42     than the PicoGUI panel
    43 
    44   - Fullscreen or any other special modes
    45 
    46   - Support for indexed and grayscale modes
    47 
    48   - Probably much more...
