Introduction to sdl12-compat
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 code
is a compatibility layer; it provides a binary and source
compatible API for programs written against SDL 1.2, but it uses
SDL 2.0 behind the scenes.

Note
Development versions of BLFS may not build or run some packages
properly if LFS or dependencies have been updated since the most
recent stable versions of the books.
Package Information
SDL Dependencies
Required
CMake-3.30.5, GLU-9.0.3, and SDL2-2.30.8
Installation of sdl12-compat
Install sdl12-compat by running
the following commands:
mkdir build &&
cd build &&
cmake -D CMAKE_INSTALL_PREFIX=/usr \
-D CMAKE_BUILD_TYPE=RELEASE \
.. &&
make
Now, as the root user:
make install &&
rm -vf /usr/lib/libSDLmain.a
Testing SDL
If you wish, test the sdlcompat
package using the included test programs. It is not required to
install any of the resulting binaries to validate the installation.
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.
