SDL-1.2.15
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-10.1
platform.

Installation of SDL
Install SDL by running the
following commands:
sed -e '/_XData32/s:register long:register _Xconst long:' \
-i src/video/x11/SDL_x11sym.h &&
./configure --prefix=/usr --disable-static &&
make
Now, as the root user:
make install &&
install -v -m755 -d /usr/share/doc/SDL-1.2.15/html &&
install -v -m644 docs/html/*.html \
/usr/share/doc/SDL-1.2.15/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
sed -e ...: This
command fixes compilation with libX11-1.6.0 and later.
--disable-static: This
switch prevents installation of static versions of the libraries.
--disable-alsa-shared: This switch
disables dynamically loading ALSA shared libraries.
--disable-sdl-dlopen: This switch
disables using dlopen for shared object loading. Loading image
backend libraries like libpng dynamically on the fly does not work.
--disable-x11-shared: This switch
disables dynamically loading X11 shared libraries.
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.
