List of Well Known C++ namespaces

I recently (Nov 2018) googled this blog title‘s and was surprised by the lack search results with a simple clear list of C++ commonly used namespaces. Obviously there could be millions of namespaces in use, but this page will attempt to catalog “common” namespaces to help developers avoid collision when starting development of their own C++ libraries.

Please feel free to comment or send me a note with other C++ namespaces people may want to be aware of.

Without further delay —

Super common:


Good to know about:

  • QP – embedded software event driven / state machine frame work
  • arma – C++ library for linear algebra & scientific computing
