SDL2-2.30.6

Introduction to SDL2

The Simple DirectMedia Layer Version 2 (SDL2 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 12.2 platform.

SDL2 Dependencies

Recommended

Optional

alsa-lib-1.2.12, Doxygen-1.12.0 (to create documentation), ibus-1.5.30, libsamplerate-0.2.2, libunwind-1.6.2, NASM-2.16.03, pipewire-1.2.3, PulseAudio-17.0, a graphical environment, DirectFB, fcitx, jack, and sndio

Installation of SDL2

Install SDL2 by running the following commands:

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

If you have Doxygen-1.12.0 installed and want to build the html documentation, run the following commands:

pushd docs  &&
  doxygen   &&
popd
[Note]

Note

If you wish to build and run the package regression tests, do not delete the static libraries below until after the tests are built.

Now, as the root user:

make install              &&
rm -v /usr/lib/libSDL2*.a

If you built the documentation, install it as the root user:

install -v -m755 -d        /usr/share/doc/SDL2-2.30.6/html &&
cp -Rv  docs/output/html/* /usr/share/doc/SDL2-2.30.6/html

Testing SDL2

If you wish to, test the installation of SDL2 using the included test programs. None of the resulting binaries need to be installed. Issue the following commands to build the test programs:

cd test &&
./configure &&
make

Each of the test programs (they are listed in the README file in this directory) will need to be run individually. Many of them will need to be manually killed. Additionally, speakers need to be on with the volume at a suitable level.

Command Explanations

rm -v /usr/lib/libSDL2*.a: Normally static libraries can be disabled with a --disable-static option to configure, but that breaks the build in this package.
