A modern open source C++ FIX framework featuring complete schema driven customisation, high performance and fast application development.

The system is comprised of a compiler for generating C++ message and field encoders, decoders and instantiation tables; a runtime library to support the generated code and framework; and a set of complete client/server test applications.

• Fix8 helps you get your FIX protocol client or server up and running quickly. Using one of the standard FIX schemas you can have a FIX client or server up and running in next to no time.

• Statically compile your FIX xml schema and quickly build your FIX application on top. If you need to add customised messages or fields, simply update the schema and recompile.

• Fix8 is the fastest C++ Open Source FIX framework. Our testing shows that Fix8 is on average 60% faster encoding/decoding the same message than Quickfix. See Performance to see how we substantiate this shameless bragging.

• Fix8 supports standard FIX4.X to FIX5.X and FIXT1.X. If you have a custom FIX variant Fix8 can use that too. New FIX versions will be supported.

• Fix8 offers message recycling and a meta-data aware test harness. Incorporates lock free queues, atomics and many other modern techniques.

• Fix8 contains a built-in unit test framework that's being continually revised and extended. Fix8 also has a metadata driven test harness that can be scripted to support captured or canned data playback.

• Fix8 is a complete C++ FIX framework, including client/server session and connection classes; support for the standard FIX field types; FIX printer, async logger, async message persister and XML configuration classes.

• Fix8 statically supports nested components and groups to any depth. The Fix8 compiler and runtime library takes the pain out of using repeating groups.

• Fix8 applications are fast. On production level hardware, client NewOrderSingle encode latency is now 2.2us, and ExecutionReport decode 4.5us. Without the framework overhead, NewOrderSingle encode latency is 1.6us. This is being continually improved.

• Fix8 has been designed to be extended, customised or enhanced. If you have special requirements, Fix8 provides a flexible platform to develop your application on.

• Fix8 supports field and value domain validation, mandatory/optional field assertion, field ordering, well-formedness testing, retransmission and standard session semantics.

• Fix8 runs under industry standard Linux on IA32, x86-64, Itanium, PowerPC and ARM. It also now runs on Windows. Other *NIX variants may work too.

Documentation is available at API Documentation. All the source code is self-documenting using doxygen.

Fix8 requires the following third-party software (header files and libraries) being installed to build properly:

• Poco C++ Libraries basic edition

Additional libraries are needed for building on Windows, see here.

You can either choose the internally supplied Fastflow or use...

• Intel Threading Building Blocks OSS edition

If you wish to build the html documentation, you will need:

• Doxygen

If you wish to use BerkeleyDB for message persistence:

• Berkeley DB C++

The build system is based on automake/autoconf/libtool. You must have libtool installed to build.

% tar xvzf fix8-0.9.4.tar.gz
% cd 0.9.4
% ./configure
% make
% make install

If you have built the test cases, you can also run them as follows:

% make check

Please see This document for detailed instructions on building for Windows.
