Fixed bug 1582 - Allow disabling SDL_VIDEO_DRIVER_WINDOWS

Marcus von Appen

Trying to build SDL 2.x (HG) on Win32 platforms with either VS.NET or MinGW requires one to have the video subsystem and SDL_VIDEO_DRIVER_WINDOWS flag enabled due to the helper window creation routines.

The attached patch changes the helper window creation behaviour, so that one can build SDL2 without the video subsystem or Windows video drivers on Win32 platforms.

     2 * Porting To A New Platform
     3 
     4   The first thing you have to do when porting to a new platform, is look at
     5 include/SDL_platform.h and create an entry there for your operating system.
     6 The standard format is __PLATFORM__, where PLATFORM is the name of the OS.
     7 Ideally SDL_platform.h will be able to auto-detect the system it's building
     8 on based on C preprocessor symbols.
     9 
    10 There are two basic ways of building SDL at the moment:
    11 
    12 1. The "UNIX" way:  ./configure; make; make install
    13 
    14    If you have a GNUish system, then you might try this.  Edit configure.in,
    15    take a look at the large section labelled:
    16 	"Set up the configuration based on the target platform!"
    17    Add a section for your platform, and then re-run autogen.sh and build!
    18 
    19 2. Using an IDE:
    20 
    21    If you're using an IDE or other non-configure build system, you'll probably
    22    want to create a custom SDL_config.h for your platform.  Edit SDL_config.h,
    23    add a section for your platform, and create a custom SDL_config_{platform}.h,
    24    based on SDL_config.h.minimal and SDL_config.h.in
    25 
    26    Add the top level include directory to the header search path, and then add
    27    the following sources to the project:
    28 	src/*.c
    29 	src/atomic/*.c
    30 	src/audio/*.c
    31 	src/cpuinfo/*.c
    32 	src/events/*.c
    33 	src/file/*.c
    34 	src/haptic/*.c
    35 	src/joystick/*.c
    36 	src/power/*.c
    37 	src/render/*.c
    38 	src/stdlib/*.c
    39 	src/thread/*.c
    40 	src/timer/*.c
    41 	src/video/*.c
    42 	src/audio/disk/*.c
    43 	src/audio/dummy/*.c
    44 	src/video/dummy/*.c
    45 	src/haptic/dummy/*.c
    46 	src/joystick/dummy/*.c
    47 	src/main/dummy/*.c
    48 	src/thread/generic/*.c
    49 	src/timer/dummy/*.c
    50 	src/loadso/dummy/*.c
    51 
    52 
    53 Once you have a working library without any drivers, you can go back to each
    54 of the major subsystems and start implementing drivers for your platform.
    55 
    56 If you have any questions, don't hesitate to ask on the SDL mailing list:

    59 Enjoy!
