To configure the build, Confluo uses CMake as its build system. Confluo only supports out of source builds; the simplest way to configure the build would be as follows:

cd confluo
mkdir -p build
cd build
cmake ..

It is possible to configure the build specifying certain options based on requirements; the supported options are:

  • BUILD_TESTS: Builds all tests (ON by default)
  • BUILD_RPC: Builds the rpc daemon and client libraries (ON by default)
  • BUILD_EXAMPLES: Builds Confluo examples (ON by default)
  • BUILD_DOC: Builds Confluo documentation (OFF by default)
  • WITH_PY_CLIENT: Builds Confluo python rpc client (ON by default)
  • WITH_JAVA_CLIENT: Builds Confluo java rpc client (ON by default)

In order to explicitly enable or disable any of these options, set the value of the corresponding variable to ON or OFF as follows:


Finally, you can configure the install location for Confluo by modifying the CMAKE_INSTALL_PREFIX variable (which is set to /usr/local by default):

cmake -DCMAKE_INSTALL_PREFIX=/path/to/installation


Once the build is configured, you can proceed to compile, test and install Confluo.

To build, use:



make -j{NUM_CORES}

to speed up the build on multi-core systems.

To run the various unit tests, run:

make test

and finally, to install, use:

make install
