# Build and install [Fluent Bit](https://fluentbit.io) uses [CMake](https://cmake.org) as its build system. ## Requirements To build and install Fluent Bit from source, you must also install the following packages: * `bison` * `build-essentials` * `cmake` (version 3.31.6 or later) * `flex` * `libssl-dev` * `libyaml-dev` * `pkg-config` Additionally, certain [input](https://docs.fluentbit.io/manual/data-pipeline/inputs) or [output](https://docs.fluentbit.io/manual/data-pipeline/outputs) plugins might depend on additional components. For example, some plugins require Kafka. ## Prepare environment If you already know how CMake works, you can skip this section and review the available [build options](#general-options). The following steps explain how to build and install the project with the default options. 1. Change to the `build/` directory inside the Fluent Bit sources: ```shell cd build/ ``` 2. Let [CMake](https://cmake.org) configure the project specifying where the root path is located: ```shell cmake ../ ``` This command displays a series of results similar to: ``` -- The C compiler identification is GNU 4.9.2 -- Check for working C compiler: /usr/bin/cc -- Check for working C compiler: /usr/bin/cc -- works -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- The CXX compiler identification is GNU 4.9.2 -- Check for working CXX compiler: /usr/bin/c++ -- Check for working CXX compiler: /usr/bin/c++ -- works ... -- Could NOT find Doxygen (missing: DOXYGEN_EXECUTABLE) -- Looking for accept4 -- Looking for accept4 - not found -- Configuring done -- Generating done -- Build files have been written to: /home/edsiper/coding/fluent-bit/build ``` 3. Start the compilation process using the `make` command: ```shell make ``` This command displays results similar to: ``` Scanning dependencies of target msgpack [ 2%] Building C object lib/msgpack-1.1.0/CMakeFiles/msgpack.dir/src/unpack.c.o [ 4%] Building C object lib/msgpack-1.1.0/CMakeFiles/msgpack.dir/src/objectc.c.o [ 7%] Building C object lib/msgpack-1.1.0/CMakeFiles/msgpack.dir/src/version.c.o ...

Linking C executable ../bin/fluent-bit [100%] Built target fluent-bit-bin ``` 4. To continue installing the binary on the system, use `make install`: ```shell make install ``` If the command indicates insufficient permissions, prefix the command with `sudo`. ## Build options Fluent Bit provides configurable options to CMake that can be enabled or disabled. ### General options | Option | Description | Default | | ------------------------ | --------------------------------------------------------------------------------------------------------------------------- | ----------------------------- | | `FLB_ALL` | Enable all features available | `No` | | `FLB_ARROW` | Build with Apache Arrow support | `No` | | `FLB_AVRO_ENCODER` | Build with Avro encoding support | `No` | | `FLB_AWS` | Enable AWS support | `Yes` | | `FLB_AWS_ERROR_REPORTER` | Build with AWS error reporting support | `No` | | `FLB_BENCHMARKS` | Enable benchmarks | `No` | | `FLB_BINARY` | Build executable | `Yes` | | `FLB_CHUNK_TRACE` | Enable chunk traces | `Yes` | | `FLB_COVERAGE` | Build with code-coverage | `No` | | `FLB_CONFIG_YAML` | Enable YAML configuration support | `Yes` | | `FLB_CORO_STACK_SIZE` | Set coroutine stack size | | | `FLB_CUSTOM_CALYPTIA` | Enable Calyptia Support | `Yes` | | `FLB_ENFORCE_ALIGNMENT` | Enable limited platform specific aligned memory access | `No` | | `FLB_EXAMPLES` | Build examples | `Yes` | | `FLB_HTTP_SERVER` | Enable HTTP Server | `Yes` | | `FLB_INOTIFY` | Enable Inotify support | `Yes` | | `FLB_JEMALLOC` | Build with Jemalloc support | `No` | | `FLB_KAFKA` | Enable Kafka support | `Yes` | | `FLB_LUAJIT` | Enable Lua scripting support | `Yes` | | `FLB_METRICS` | Enable metrics support | `Yes` | | `FLB_MTRACE` | Enable `mtrace` support | `No` | | `FLB_PARSER` | Build with Parser support | `Yes` | | `FLB_POSIX_TLS` | Force POSIX thread storage | `No` | | `FLB_PROFILES` | Enable profiles support | `Yes` | | `FLB_PROXY_GO` | Enable Go plugins support | `Yes` | | `FLB_RECORD_ACCESSOR` | Enable record accessor | `Yes` | | `FLB_REGEX` | Build with Regex support | `Yes` | | `FLB_RELEASE` | Build with release mode (`-O2 -g -DNDEBUG`) | `No` | | `FLB_SHARED_LIB` | Build shared library | `Yes` | | `FLB_SIGNV4` | Enable AWS Signv4 support | `Yes` | | `FLB_SIMD` | Enable SIMD support | `No` | | `FLB_SQLDB` | Enable SQL embedded database support | `Yes` | | `FLB_STATIC_CONF` | Build binary using static configuration files.
