LibSDL-1.2.15 for OS4.1 Final Edition
=====================================

This is a port of the multimedia library SDL (Simple Directmedia Layer) for
AmigaOS 4.1. For more information on SDL, see the included material and the
SDL web site: http://www.libsdl.org/.

This implementation is a fresh port of SDL for AmigaOS 4.1. It does not share
code with the existing 68k AmigaOS or MorphOS versions of SDL (although the
CD-ROM support used the MorphOS SDL as a reference).

SDL for AmigaOS 4.1 is still a work in progress. What functionality exists
has proven to be stable, but some features of SDL are not yet supported.


Supported features
==================

* Supports display surfaces as a window on your Workbench screen or
  full-screen on a custom screen. Windowed surfaces will work on high- or
  true-colour Workbench screens only, not on palette-mapped screens
  (full-screen surfaces can be opened as an 8-bit, palette-mapped screen).
  Only Picasso96 screens are supported at the moment; it will not work at
  all on screens generated by the classic Amiga's custom chip-sets (and
  probably never will).

* Full-screen, double-buffered display surfaces (synchronized with your
  monitor's vertical retrace, if your graphics card driver supports that).

* Hardware surfaces. (That is, surfaces in video memory rather than main
  memory. Note that this may not necessarily give better performance. It
  depends how you use the surface.)

* Hardware acceleration for blitting and rect-fills within in hardware
  surface.

* Alpha-blending is supported via compositing feature. (requires
  graphics.library v53 or better)

* Altivec acceleration for many plain, colour-keyed and alpha blits between
  software surfaces only.

* OpenGL surfaces are mostly supported and require minigl.library. The
  deprecated SDL_OPENGLBLIT surfaces don't work yet.

* Input-grabbing in windowed mode.

* Audio output via AHI.

* Joystick support (this requires AmigaInput.library v51 or better).

* Full threading support.

* An ELF shared object.


Not yet supported
=================

* Video overlays (this cannot yet be supported due to P96 limitations).

* Gamma functions (this cannot yet be supported due to P96 limitations).


Building
========

1) With configure (supports only static link library at the moment!)

    sh configure --disable-pthreads
    make

2) With native makefile

    make -f makefile.amigaos4


WinUAE
======

Because WinUAE doesn't support hardware-accelerated compositing or 3D, you need
to install the following software:

etags.lha
