How to build

(Last update: Jan/24/2023)

You have two ways to enable QUIC on ATS:

• Use Quiche library
  • This uses Quiche's QUIC implementation
• Use an SSL library that supports QUIC (i.e. BoringSSL, or OpenSSL from quictls)
  • This uses ATS's QUIC implementation

...

Currently ATS is compatible with Quiche 0.1416.0.

Please refer to the official documents for the build step. You need to enable ffi feature at minimum. qlog is also available.

10-Dev branch)

Quiche support is only available on quiche branch at the moment.

$ git clone --depth 1 --branch quiche10-Dev https://github.com/apache/trafficserver
$ cd trafficserver
$ ./configure --prefix=/PATH/TO/ATS --with-quiche=/PATH/TO/QUICHE --enable-debug
$ make
$ make install

...

There is a script that builds third-party tools in the repo. It builds h2load and curl with HTTP/3 support. An HTTP/3 client under ngtcp2/example is also useful when you want to check details.
