I managed to work around this problem via the brew bison:

export PATH=/usr/local/Cellar/bison/3.4.1/bin:$PATH
````

... but I run into other build issues also.

$ /usr/local/Cellar/bison/3.4.1/bin/bison --version
bison (GNU Bison) 3.4.1

@nigels-com Please write the issues that you are facing if it is not solved yet.

hmm so we basically need Bison >= 3.3

So far I've doing fluent bit development on a linux machine, today I tried using my Mac, and I got a similar issue (while trying to build the latest commit in master):

You'll need a newer bison than 2.3.

-- Found FLEX: /usr/bin/flex (found version "2.5.35")
-- Found BISON: /usr/local/opt/bison/bin/bison (found version "3.4.1")

I am getting the same issue post bison version upgrade to 3.7.2

@pratibhamoogi In case if you have upgraded bison, after you ran the cmake command in fluent-bit source, then you need to remove the content inside the build directory and and run the _cmake_ command again.

One way to verify that, there is a file called _CMakeCache.txt_ in _build_ directory and search following file path

BISON_EXECUTABLE:FILEPATH=/usr/local/bin/bison

I believe in your OS /usr/local/bin has the highest priority. You can check that by running

cat /etc/paths
