手元の MacBook Pro (13-inch, 2020, Four Thunderbolt 3 ports) (2.3 GHz Quad-Core Intel Core i7) の MacOS 12.3.1 Monterey に Fluent Bit の最新版 (v3.0.0) のインストールを試みた。git clone してインストールした。 HomeBrew でインストールできそうだが、NestDAQ ではソースからコンパイルするのが基本路線なので、それに従う。

インストールのコマンドは以下の通り。

$ cd $HOME/nestdaq/src
$ git clone https://github.com/fluent/fluent-bit
$ cd fluent-bit
$ git describe --tags
v2.2.2-4-g5dec222d0
$ cmake -DCMAKE_INSTALL_PREFIX=$HOME/nestdaq \
  -B ./build -S .
$ cd build
$ time make -j6
...
real	2m28.809s
user	5m21.579s
sys	1m46.630s
$ make install
$ fluent-bit
Fluent Bit v3.0.0

ロゴの中のバージョンが v2.2.2 と書いてあるのが気になるが、git のタグのバージョンが表示されてる？なんで整合性がないかよくわからない。Crtl-c で終了。fluent-bit –version とすると、以下のように表示される。

$ fluent-bit --version
Fluent Bit v3.0.0
Git commit: 5dec222d060f7f2a22440e6fc6b07e8892b72ec1

fluent-bit-do-redis-output を clone する

brew で FLEX と BISON をインストールする。

$ brew install flex bison

これで cmake が通るようになった。
