Requirements

For the next steps, you will need to have Homebrewarrow-up-right installed in your system, if is not there, you can install it with the following command:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

hashtag
Install build dependencies

Run the following brew command in your terminal to retrieve the dependencies:

brew install git cmake openssl bison

hashtag
Get the source and build it

Grab a fresh copy of the Fluent Bit source code (upstream):

git clone https://github.com/fluent/fluent-bit
cd fluent-bit

Optionally, if you want to use a specific version, just checkout to the proper tag. If you want to use v1.8.13 just do:

git checkout v1.8.13

In order to prepare the build system, we need to expose certain environment variables so Fluent Bit CMake build rules can pick the right libraries:

export OPENSSL_ROOT_DIR=`brew --prefix openssl`
export PATH=`brew --prefix bison`/bin:$PATH

Change to the build/ directory inside the Fluent Bit sources:

Build Fluent Bit. Note that we are indicating to the build system "where" the final binaries and config files should be installed:

Install the data. Note that this requires root privileges due to the directory we will write information to:

The binaries and configuration examples can be located at /opt/fluent-bit/.

Optionally, if you want to use a specific version, just checkout to the proper tag. If you want to use v1.9.2 just do:

In order to prepare the build system, we need to expose certain environment variables so Fluent Bit CMake build rules can pick the right libraries:

And then, creating the specific macOS SDK target (For example, sepcifying macOS Big Sur (11.3) SDK environment):

Change to the build/ directory inside the Fluent Bit sources:

Build Fluent Bit macOS installer.

Then, macOS installer will be generated as:

Finally, fluent-bit-<fluent-bit version>-(intel or apple).pkg will be generated.

The created installer will put binaries at /opt/fluent-bit/.
