How to install catch2

Catch2 is developer utility. What follows is background, not a walkthrough. The authoritative version always lives with the project's own team.

Paths onto a machine

In practice this means one of a handful of routes: an operating system package index, a registry tied to a language, a version manager, or a source tree built with the project's own tooling. Which one applies is decided by the platform and by the maintainers.

Who is behind it

Ownership sits with the project's own contributors. Release cadence, supported platforms and documentation are all decided by them, and none of it is mediated here.

Before touching anything

Check platform support first. Recent work in this space generally assumes a current runtime and a reasonably modern system.

Reading the outcome

When results differ from expectations, check what is actually being picked up. Duplicate copies and stale caches are the usual explanation.

What this domain is

These pages exist as notes. No files are hosted, and no project material is reproduced on this domain.

A note on older machines

Hardware age matters more than people expect here. Recent releases tend to assume modern runtimes and current system libraries, so an ageing machine can rule out the newest version entirely.
