brotli-1.0.7

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.

本パッケージは LFS-10.0 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。

  • Download size: 23 MB

  • Estimated disk space required: 43 MB (add 5 MB if installing both sets of python bindings, add 9 MB for the main test and 5MB for testing the bindings)

  • Estimated build time: 0.2 SBU (add 0.3 SBU for the python bindings, and 1.2 SBU if testing them)

Brotli Dependencies

Required

CMake-3.18.1

Optional

Python-2.7.18 (to create python2 bindings)

User Notes: http://wiki.linuxfromscratch.org/blfs/wiki/brotli

Installation of Brotli

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, either or both sets of python bindings can be built and installed without any conflicts. If you need the Python2 bindings, add or substitute python2 for python3 in the following instructions: 

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

If you 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 either or both sets of python bindings, install them as the root user (as before, use the appropriate version(s) of python: 

python3 setup.py install --optimize=1
