First, you need libfluent-bit.so Alien::FluentBit helps you with this by building one from source. The binary dist from github.com/fluent/fluent-bit currently does not work with perl without adding the library to LD_PRELOAD which is not a great solution.

apt-get install cmake flex bison m4 # not required, but speeds things up cpanm Alien::FluentBit 

Now you can install the module:

cpanm Fluent-LibFluentBit-0.02.tar.gz 

or:

tar -xf Fluent-LibFluentBit-0.02.tar.gz cd Fluent-LibFluentBit-0.02 perl Makefile.PL make make test make install 

Download or checkout the source code, then:

dzil --authordeps | cpanm dzil test 

To build and run single unit tests, use the 'dtest' script:

./dtest t/10-output-to-datadog.t 

To build and install a trial version, use

V=0.02_01 dzil build cpanm Fluent-LibFluentBit-0.02_01.tar.gz
