ossec on macOS

Just a few notes how I got ossec, the host intrusion detection system, up and running on a Mac M1.

You need the command line tools installed with xcode-select —install and homebrew ready on your system.

• Run brew install pcre2 openssl

• Download the source tar ball from https://www.ossec.net/download-ossec/ and then…

  $ tar xvfz ossec-*

  $ cd ossec-*

  $ export CPATH=/opt/homebrew/include/

  $ export LIBRARY_PATH=/opt/homebrew/lib

  $ ln -s /opt/homebrew/Cellar/openssl@1.1/1.1.1k/include/openssl/ /opt/homebrew/include/openssl

  $ ./install.sh
