Added automated test to Xcode project plus needed changes to SDL_RWFromFile to be OS X bundle aware. The Mac OS X project has a new target called testsdl which builds the automated test. I looked at using Xcode's native unit test support, but the impedance mismatch between the existing automated test structure and Apple's was more than I could handle. As such, the testsdl application is a full blown proper OS X application, which means it is a self-contained .app bundle. This immediately revealed some problems from the automated test. The largest problem was the assumption about the current working directory and where to find resources. (I suspect Windows may have a similar problem depending on circumstance.) To open resources, the test was looking in directories relative to the SDL source directory, but this will not work well with self-contained .app bundles and Xcode which can place its built applications almost anywhere. And for real-world situations, this is pretty useless anyway. So I modified SDL_RWFromFile to do special things on OS X. First, it will look for a file in the .app bundle. If not found, it will fallback and just call fopen as it used to do. I also had to modify the automated test itself because it had a contrieved test which called fopen directly to do read from an existing FILE pointer. In addition, there was a write test. Since a .app bundle is likely going to be read-only, I added a special case for OS X to write to NSTemporaryDirectory. I expect these changes should work for both Mac and iPhone OS (which includes iPad). I will update the iPhone Xcode project next. Finally, FYI, the X11 automated test seems to be failing. Below is my output.

SDL on DirectFB

Supports:

- Hardware YUV overlays
- OpenGL - software only
- 2D/3D accelerations (depends on directfb driver)
- multiple displays
- windows

What you need:

DirectFB 1.0.1, 1.2.x, 1.3.0
Kernel-Framebuffer support: required: vesafb, radeonfb .... 
Mesa 7.0.x	   - optional for OpenGL

/etc/directfbrc

This file should contain the following lines to make
your joystick work and avoid crashes:
------------------------
disable-module=joystick
disable-module=cle266
disable-module=cyber5k
no-linux-input-grab
------------------------

To disable to use x11 backend when DISPLAY variable is found use

export SDL_DIRECTFB_X11_CHECK=0

To disable the use of linux input devices, i.e. multimice/multikeyboard support,
use

export SDL_DIRECTFB_LINUX_INPUT=0

To use hardware accelerated YUV-overlays for YUV-textures, use:

export SDL_DIRECTFB_YUV_DIRECT=1

This is disabled by default. It will only support one 
YUV texture, namely the first. Every other YUV texture will be
rendered in software.

In addition, you may use (directfb-1.2.x)

export SDL_DIRECTFB_YUV_UNDERLAY=1

to make the YUV texture an underlay. This will make the cursor to
be shown.

Simple Window Manager
=====================

The driver has support for a very, very basic window manager you may
want to use when runnning with "wm=default". Use

export SDL_DIRECTFB_WM=1

to enable basic window borders. In order to have the window title rendered,
you need to have the following font installed:

/usr/share/fonts/truetype/freefont/FreeSans.ttf

OPENGL Support
==============

As of this writing 20070810 you need to pull Mesa from git and do the following:

------------------------
cd mesa 
make linux-directfb
make

echo Installing - please enter sudo pw.

sudo make install INSTALL_DIR=/usr/local/dfb_GL
cd src/mesa/drivers/directfb
make
sudo make install INSTALL_DIR=/usr/local/dfb_GL
------------------------

To run the SDL - testprograms:

export SDL_VIDEODRIVER=directfb
export LD_LIBRARY_PATH=/usr/local/dfb_GL/lib
export LD_PRELOAD=/usr/local/dfb_GL/libGL.so.7

./testgl
