Introduction

XQUIC Library released by Alibaba is …

… a client and server implementation of QUIC and HTTP/3 as specified by the IETF. Currently supported QUIC versions are v1 and draft-29.

… OS and platform agnostic. It currently supports Android, iOS, HarmonyOS, Linux, macOS and Windows(v1.2.0). Most of the code is used in our own products, and has been tested at scale on android, iOS apps, as well as servers.

… still in active development. Interoperability is regularly tested with other QUIC implementations.

Requirements

To build XQUIC, you need

CMake
BoringSSL or BabaSSL

To run test cases, you need

libevent
CUnit

QuickStart Guide

XQUIC can be built with BabaSSL(Tongsuo) or BoringSSL.

Build with BoringSSL

sudo apt-get install -y build-essential libevent-dev

# get XQUIC source code
git clone https://github.com/alibaba/xquic.git; cd xquic

# get and build BoringSSL
git clone https://github.com/google/boringssl.git ./third_party/boringssl; cd ./third_party/boringssl
mkdir -p build && cd build
cmake -DBUILD_SHARED_LIBS=0 -DCMAKE_C_FLAGS="-fPIC" -DCMAKE_CXX_FLAGS="-fPIC" ..
make -j ssl crypto
cd ..
SSL_TYPE_STR="boringssl"
SSL_PATH_STR="${PWD}"
cd ../..

# build XQUIC with BoringSSL
# When build XQUIC with boringssl, by default XQUIC will use boringssl
# in third_party. If boringssl is deployed in other directories, SSL_PATH could be 
# used to specify the search path of boringssl
git submodule update --init --recursive
mkdir -p build; cd build
cmake -DGCOV=on -DCMAKE_BUILD_TYPE=Debug -DXQC_ENABLE_TESTING=1 -DXQC_SUPPORT_SENDMMSG_BUILD=1 -DXQC_ENABLE_EVENT_LOG=1 -DXQC_ENABLE_BBR2=1 -DXQC_ENABLE_RENO=1 -DSSL_TYPE=${SSL_TYPE_STR} -DSSL_PATH=${SSL_PATH_STR} ..

# exit if cmake error
if [ $? -ne 0 ]; then
    echo "cmake failed"
    exit 1
fi

make -j

Build with BabaSSL(Tongsuo)

sudo apt-get install -y build-essential libevent-dev

# get XQUIC source code
git clone https://github.com/alibaba/xquic.git; cd xquic

# get and build BabaSSL(Tongsuo)
git clone -b 8.3-stable https://github.com/Tongsuo-Project/Tongsuo.git ./third_party/babassl; cd ./third_party/babassl/
./config --prefix=/usr/local/babassl
make -j
SSL_TYPE_STR="babassl"
SSL_PATH_STR="${PWD}"
cd -

# build XQUIC with BabaSSL
# When build XQUIC with babassl, /usr/local/babassl directory will be searched
# as default. If babassl is deployed in other directories, SSL_PATH could be 
# used to specify the search path of babassl
git submodule update --init --recursive
mkdir -p build; cd build
cmake -DGCOV=on -DCMAKE_BUILD_TYPE=Debug -DXQC_ENABLE_TESTING=1 -DXQC_SUPPORT_SENDMMSG_BUILD=1 -DXQC_ENABLE_EVENT_LOG=1 -DXQC_ENABLE_BBR2=1 -DXQC_ENABLE_RENO=1 -DSSL_TYPE=${SSL_TYPE_STR} -DSSL_PATH=${SSL_PATH_STR} ..

# exit if cmake error
if [ $? -ne 0 ]; then
    echo "cmake failed"
    exit 1
fi

make -j
