Chapter 38. Multimedia Libraries and Drivers

SDL-1.2.14

Introduction to SDL

The Simple DirectMedia Layer (SDL for short) is a cross-platform library designed to make it easy to write multimedia software, such as games and emulators.

This package is known to build and work properly using an LFS-7.0 platform.

Installation of SDL

This package (unfortunately) expects the X Window system to be installed in the /usr/X11R6 directory. If you're using a recent version of Xorg and it is installed in any other location, ensure you have followed the instructions in the Creating an X11R6 Compatibility Symlink section.

Install SDL by running the following commands: 

./configure --prefix=/usr &&
make

Now, as the root user: 

make install &&

install -v -m755 -d /usr/share/doc/SDL-1.2.14/html &&
install -v -m644    docs/html/*.html \
                    /usr/share/doc/SDL-1.2.14/html

Testing SDL

If you wish to, test the installation of SDL using the included test programs. It is not required to install any of the resulting binaries to validate the installation. Issue the following commands to build the test programs: 

cd test &&
./configure &&
make

You'll need to manually run all the test programs (they are listed in the README file in this directory). Many of them will need to be manually killed, and you'll need to turn your speakers on with the volume at a suitable level.

Command Explanations

--disable-static: prevent static libraries being built and installed.

Configuring SDL

Configuration Information

As with most libraries, there is no configuration to do, save that the library directory, i.e., /opt/lib or /usr/local/lib should appear in /etc/ld.so.conf so that ldd can find the shared libraries. After checking that this is the case, /sbin/ldconfig should be run while logged in as root.

Contents

Installed Program: sdl-config
Installed Libraries: libSDL.{so,a} and libSDLmain.a
Installed Directories: /usr/include/SDL and /usr/share/doc/SDL-1.2.14

Short Descriptions

sdl-config

determines the compile and linker flags that should be used to compile and link programs that use libSDL.

libSDL.{so,a}

library provides low level access to audio, keyboard, mouse, joystick, 3D hardware via OpenGL, and 2D frame buffer across multiple platforms.
