A service-oriented framework to provide a computing environment for efficient Big Data processing.

Clara requires a C++17 compiler and CMake 3.16+

Install GCC and CMake from the repositories:

$ sudo apt install build-essential cmake

Install Xcode command line tools:

$ xcode-select --install

Install CMake using Homebrew:

$ brew install cmake

Clara uses an internal pub-sub messaging library, which requires Protocol Buffers and ZeroMQ.

Install from the repositories:

$ sudo apt install libzmq5-dev libprotobuf-dev protobuf-compiler

Use Homebrew:

$ brew install zeromq protobuf

To build with CMake a configure wrapper script is provided:

$ ./configure --prefix="$CLARA_HOME"
$ make
$ make install

This will install Clara C++ into the location of your Clara distribution.

The main Clara Java implementation should also be already installed in $CLARA_HOME to run C++ services with the standard orchestrator and the Clara shell.
