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.

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.

Install brotli by running the following commands:
mkdir build &&
cd build &&
cmake -D CMAKE_INSTALL_PREFIX=/usr \
-D CMAKE_BUILD_TYPE=Release \
.. &&
make
To test the results, issue: make test.
Now, as the root user:
make install
If desired, build the Python3 bindings:
cd .. &&
sed "/c\/.*\.[ch]'/d;\
/include_dirs=\[/\
i libraries=['brotlicommon','brotlidec','brotlienc']," \
-i setup.py &&
pip3 wheel -w dist --no-build-isolation --no-deps --no-cache-dir $PWD
Install the Python3 bindings as
the root user:
pip3 install --no-index --find-links=dist --no-cache-dir --no-user Brotli
To test the Python3 binding, issue: pytest.
sed ... -i setup.py:
Stop setup.py from rebuilding the
entire package all over again, use the already installed libraries
for the Python3 binding instead.
