Open Source C++ Frameworks for Linux

wxWidgets is a C++ library that lets developers create applications for Windows, Mac OS X, Linux and other platforms with a single code base. It has popular language bindings for Python, Perl, Ruby and many other languages, and unlike other cross-platform toolkits, wxWidgets gives applications a truly native look and feel because it uses the platform's native API rather than emulating the GUI. It's also extensive, free, open-source and mature.

QP real-time event frameworks (RTEFs) provide lightweight, modern, event-driven architecture based on asynchronous Active Objects (Actors) and Hierarchical State Machines. The matching QM model-based design tool and other host-based tools complement the QP frameworks by supporting graphical modeling, code generation, software tracing, and unit testing for event-driven embedded software. Visit https://www.state-machine.com for more information. The QP RTEFs can run on bare-metal microcontrollers, replacing a traditional RTOS. The frameworks contain a selection of built-in real-time kernels (RTOS kernels), such as the cooperative QV kernel, the preemptive non-blocking QK kernel, and the unique preemptive, dual-mode (blocking/non-blocking) QXK kernel. Native QP ports and ready-to-use examples are provided for ARM Cortex-M (M0/M0+/M3/M4/M7/M33/...) as well as other CPUs. The QP RTEFs can also work with many traditional RTOSes and General-Purpose OSes, such as Linux and Windows.

C++ Template Libraries: Biscuit Parser Library, Ketchup Message Map Library, Egg Functional Library, and Oven Range Library

The motivation of pion is not to build yet another web server or web application framework, but to help provide basic HTTP(S) functionality to new or existing C++ applications. If you're working on a Boost C++ application and would just like to use HTTP to provide a simple user interface or interact with run-time data, then pion might be for you.

SubrScene is an open source visualization toolkit and application based on OpenSceneGraph.

This is the YaST2 user interface engine that provides the abstraction from graphical user interfaces (Qt, Gtk) and text based user interfaces (ncurses). This can be used independently of YaST2 for generic (C++) applications.
