Chapter 9. General Libraries

brotli-1.0.9

Introduction to Brotli

Brotli provides a general-purpose lossless compression algorithm that compresses data using a combination of a modern variant of the LZ77 algorithm, Huffman coding and 2nd order context modeling. Its libraries are particularly used for WOFF2 fonts on webpages.

This package is known to build and work properly using an LFS-10.1 platform.

Brotli Dependencies

Required

CMake-3.20.1

Installation of Brotli

At first, fix an issue in pkg-config files: 

sed -i 's@-R..libdir.@@' scripts/*.pc.in

Install brotli by running the following commands: 

mkdir out &&
cd    out &&

cmake -DCMAKE_INSTALL_PREFIX=/usr \
      -DCMAKE_BUILD_TYPE=Release  \
      ..  &&
make

To test the results, issue: make test

If desired, build the Python3 bindings: 

pushd ..               &&
python3 setup.py build &&
popd

The python tests are missing most of the necessary testdata files and therefore 240 of 311 tests fail. If you nevertheless wish to test the bindings, go back to the top-level directory and issue: python3 setup.py test.

Now, as the root user: 

make install &&
cd ..

If you have built the python bindings, install them as the root user: 

python3 setup.py install --optimize=1
