How to Install Flame on OpenBSD

Flame is a lightweight, multi-platform software for visualizing the execution of software programs. In this tutorial, we will go through the steps required to install Flame on OpenBSD.

Prerequisites

Before installing Flame, we need to make sure that OpenBSD is up to date and has the necessary packages installed. To do this, run the following command:

sudo pkg_add git gmake py3-setuptools py3-pip

These packages are needed to install Flame.
