Download Allegro's source from git and navigate to its directory.

git clone https://github.com/liballeg/allegro5.git
cd allegro5

Naturally, you can replace the repository to something else if you want grab the code from, e.g., a GitHub fork.

If you want MP3 support, download the header-only MiniMP3 library as follows:

mkdir -p deps/include
cd deps/include
curl -O https://raw.githubusercontent.com/lieff/minimp3/master/minimp3.h
curl -O https://raw.githubusercontent.com/lieff/minimp3/master/minimp3_ex.h
cd ../..

Configure and build Allegro.

mkdir build
cd build
cmake ..
make -j$(nproc)

If you're reproducing some sort of bug or developing a new feature, it can be helpful to build Allegro in debug mode by issuing cmake .. -DCMAKE_BUILD_TYPE=Debug. The default CMAKE_BUILD_TYPE is RelWithDebInfo.

Test by running an example.

cd examples
./ex_draw_bitmap
