Open CASCADE Technology is a suite for 3D surface and solid modeling, visualization, data exchange and rapid application development. It is an excellent platform for development of numerical simulation software including CAD/CAM/CAE, AEC and GIS, as well as PDM applications.

GNU Astronomy Utilities (Gnuastro) is a collection of programs (the `gnuastro' package) and librarires (this package along with `libgnuastro-dev') for astronomical data analysis and manipulation. The programs can be run on the command-line for efficient and easy usage and the libraries can be used within C and C++ programs.

This library makes it easy to prevent server side request forgery (SSRF) attacks.

Iceoryx is an inter-process communication (IPC) middleware for POSIX based operating systems. It features shared memory capabilities which allow a true zero-copy data transfer.

This is the GNU C++ compiler, a fairly portable optimizing compiler for C++.
