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.
本パッケージは LFS-8.3 において正しくビルドでき動作することが確認されています。

ALSA-1.1.6, Doxygen-1.8.14 (to create documentation), ibus-1.5.19, NASM-2.13.03, PulseAudio-12.2, X ウィンドウシステム, DirectFB, and fcitx
User Notes: http://wiki.linuxfromscratch.org/blfs/wiki/sdl
Install SDL2 by running the following commands:
./configure --prefix=/usr && make
If you have Doxygen-1.8.14 installed and want to build the html documentation, run the following commands:
pushd docs && doxygen && popd
![[注記]](../images/note.png)
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/SDL2-2.0.8/html && cp -Rv docs/output/html/* /usr/share/doc/SDL2-2.0.8/html
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.
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.
--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.
ライブラリのほとんどは、どこにインストールされているかを定める方法がないものです。
したがってインストールされるディレクトリがどこかを捉えておく必要があります。 つまり /etc/ld.so.conf ファイル内に /opt/lib とか /usr/local/lib といったディレクトリを記述する必要が出てきます。
これを行っておかないと ldd
は共有ライブラリを見つけ出すことができません。 上の設定が必要であったなら、それを実施した上で root ユーザーでログインし /sbin/ldconfig を実行してください。
