1 SDL on DirectFB
2
3 Supports:
4
5 - Hardware YUV overlays
6 - OpenGL - software only
7 - 2D/3D accelerations (depends on directfb driver)
8 - multiple displays
9 - windows
10
11 What you need:
12
13 DirectFB 1.0.1, 1.2.x, 1.3.0
14 Kernel-Framebuffer support: required: vesafb, radeonfb ....
15 Mesa 7.0.x - optional for OpenGL
16
17 /etc/directfbrc
18
19 This file should contain the following lines to make
20 your joystick work and avoid crashes:
21 ------------------------
22 disable-module=joystick
23 disable-module=cle266
24 disable-module=cyber5k
25 no-linux-input-grab
26 ------------------------
27
28 To disable to use x11 backend when DISPLAY variable is found use
29
30 export SDL_DIRECTFB_X11_CHECK=0
31
32 To disable the use of linux input devices, i.e. multimice/multikeyboard support,
33 use
34
35 export SDL_DIRECTFB_LINUX_INPUT=0
36
37 To use hardware accelerated YUV-overlays for YUV-textures, use:
38
39 export SDL_DIRECTFB_YUV_DIRECT=1
40
41 This is disabled by default. It will only support one
42 YUV texture, namely the first. Every other YUV texture will be
43 rendered in software.
44
45 In addition, you may use (directfb-1.2.x)
46
47 export SDL_DIRECTFB_YUV_UNDERLAY=1
48
49 to make the YUV texture an underlay. This will make the cursor to
50 be shown.
51
52 Simple Window Manager
53 =====================
54
55 The driver has support for a very, very basic window manager you may
56 want to use when runnning with "wm=default". Use
57
58 export SDL_DIRECTFB_WM=1
59
60 to enable basic window borders. In order to have the window title rendered,
61 you need to have the following font installed:
62
63 /usr/share/fonts/truetype/freefont/FreeSans.ttf
64
65 OPENGL Support
66 ==============
67
68 The following instructions will give you *software* opengl. However this
69 works at least on all directfb supported platforms.
70
71 As of this writing 20100802 you need to pull Mesa from git and do the following:
72
73 ------------------------
74 git clone git://anongit.freedesktop.org/git/mesa/mesa
75 cd mesa
76 git checkout 2c9fdaf7292423c157fc79b5ce43f0f199dd753a
77 ------------------------
78
79 Edit configs/linux-directfb so that the Directories-section looks like
80 ------------------------
81 # Directories
82 SRC_DIRS = mesa glu
83 GLU_DIRS = sgi
84 DRIVER_DIRS = directfb
85 PROGRAM_DIRS =
86 ------------------------
87
88 make linux-directfb
89 make
90
91 echo Installing - please enter sudo pw.
92
93 sudo make install INSTALL_DIR=/usr/local/dfb_GL
94 cd src/mesa/drivers/directfb
95 make
96 sudo make install INSTALL_DIR=/usr/local/dfb_GL
97 ------------------------
98
99 To run the SDL - testprograms:
100
101 export SDL_VIDEODRIVER=directfb
102 export LD_LIBRARY_PATH=/usr/local/dfb_GL/lib
103 export LD_PRELOAD=/usr/local/dfb_GL/libGL.so.7
104
105 ./testgl
