    Cross compilation support (#709)

* build: add cross-compilation support to make

Set CROSS_COMPILE when running make to use the selected cross
compilation toolchain, such as arm-linux-gnueabihf, or
aarch64-linux-gnu.

Testing requires the presence of qemu - 'qemu-$(ARCH)' will be executed,
where ARCH is the first part of the toolchain triplet.

* build: add cross-compilation support to cmake

If C_COMPILER/CXX_COMPILER/CC/CXX are found to have cross-compilation
triplets in front of the compiler, then qemu will be used to execute the
tests.

* CI: add arm-linux-gnueabihf-gcc builder to Travis

The version of qemu available in Ubuntu trusty (as provided by Travis)
appears to have a bug in qemu-aarch64, which leads to the compatibility
tests failing on some inputs, erroneously rejecting the input as
corrupt.

Once Travis supports xenial, we could add an aarch64-gnu-linux-gcc
builder as well.

* CI: propagate cmake errors out of .travis.sh

Seems like even if cmake fails, the error isn't picked up by Travis.

  • BROTLI DATA COMPRESSIOM LIBRARY

Brotli is a generic-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, with a compression ratio comparable to the best
currently available general-purpose compression methods. It is similar in speed
with deflate but offers more dense compression.

The specification of the Brotli Compressed Data Format is defined in RFC 7932
https://tools.ietf.org/html/rfc7932

    Build instructions

    Autotools-style CMake

    configure-cmake is an autotools-style configure script for CMake-based projects (not supported on Windows).

    The basic commands to build, test and install brotli are:

    $ mkdir out && cd out
$ ../configure-cmake
$ make
$ make test
$ make install

    By default, debug binaries are built. To generate “release” Makefile specify --disable-debug option to configure-cmake.

    Bazel

    See Bazel

    CMake

    The basic commands to build and install brotli are:

    $ mkdir out && cd out
$ cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=./installed ..
$ cmake --build . --config Release --target install

    You can use other CMake configuration.

    Premake5

    See Premake5

    Python

    To install the latest release of the Python module, run the following:

    $ pip install brotli

    To install the tip-of-the-tree version, run:

    $ pip install --upgrade git+https://github.com/google/brotli

    See the Python readme for more details on installing from source, development, and testing.
