The master branch is for the latest version 5 release, checkout branch main-v4.3 for version 4.3 and main-v4.4 for version 4.4.

EMQX requires OTP 22 or 23 for version 4.3, and OTP 24 for 4.4 and 5.0.

git clone https://github.com/emqx/emqx.git
cd emqx
make
_build/emqx/rel/emqx/bin/emqx console

For 4.2 or earlier versions, release has to be built from another repo.

git clone https://github.com/emqx/emqx-rel.git
cd emqx-rel
make
_build/emqx/rel/emqx/bin/emqx console

Homebrew on Apple silicon changed default location of it's home directory from /usr/local to /opt/homebrew and as a result a few things broke in the process.

Concerning EMQX, when you install unixodbc package (one of the dependencies) via Homebrew, and build Erlang/OTP with kerl, kerl will not be able to find unixodbc.

Here is how to solve it:

brew install unixodbc kerl
sudo ln -s $(realpath $(brew --prefix unixodbc)) /usr/local/odbc
export CC="/usr/bin/gcc -I$(brew --prefix unixodbc)/include"
export LDFLAGS="-L$(brew --prefix unixodbc)/lib"
kerl build 24.3
mkdir ~/.kerl/installations
kerl install 24.3 ~/.kerl/installations/24.3
. ~/.kerl/installations/24.3/activate

Then you can proceed with make.
