Build and Install

​Fluent Bit uses CMake as it build system. The suggested procedure to prepare the build system consists of the following steps:
Prepare environment
In the following steps you can find exact commands to build and install the project with the default options. If you already know how CMake works you can skip this part and look at the build options available. Note that Fluent Bit requires CMake 3.x. You may need to use cmake3 instead of cmake to complete the following steps on your system.
Change to the build/ directory inside the Fluent Bit sources:
1
$ cd build/
Copied!
Let CMake configure the project specifying where the root path is located:
1
$ cmake ../
2
-- The C compiler identification is GNU 4.9.2
3
-- Check for working C compiler: /usr/bin/cc
4
-- Check for working C compiler: /usr/bin/cc -- works
5
-- Detecting C compiler ABI info
6
-- Detecting C compiler ABI info - done
7
-- The CXX compiler identification is GNU 4.9.2
8
-- Check for working CXX compiler: /usr/bin/c++
9
-- Check for working CXX compiler: /usr/bin/c++ -- works

-- Could NOT find Doxygen (missing:  DOXYGEN_EXECUTABLE)

-- Looking for accept4
13
-- Looking for accept4 - not found
14
-- Configuring done
15

-- Build files have been written to: /home/edsiper/coding/fluent-bit/build
Copied!
Now you are ready to start the compilation process through the simple make command:
1
$ make

Copied!
to continue installing the binary on the system just do:
1
$ make install
Copied!
it's likely you may need root privileges so you can try to prefixing the command with sudo.
