TheIDE is an integrated development environment for the U++ cross-platform app development framework dedicated to the C++ programming language. It can handle general-purpose C/C++ projects as well. Additionally, it is an excellent IDE for people starting their journey with C/C++ programming and looking for an easy-to-use environment with features like a simple build system, code completion, code formatting, and debugger support.U++ is a C++ cross-platform rapid application development framework focused on programmers productivity. It includes a set of libraries (GUI, SQL, Network, etc.), and an integrated development environment.Rapid development is achieved by the smart and aggressive use of C++ rather than through fancy code generators. In this respect, U++ competes with popular scripting languages while preserving C/C++ runtime characteristics.The U++ integrated development environment, TheIDE, introduces modular concepts to C++ programming. It features BLITZ-build technology to speedup C++ rebuilds up to 4 times, Visual designers for U++ libraries, a Topic++ system for documenting code and creating rich text resources for applications (like help and code documentation) and Assist++ - a powerful C++ code analyzer that provides features like code completion, navigation and transformation.TheIDE can work with GCC, Clang, MinGW and Visual C++ and contains a full featured debugger. TheIDE can also be used to develop non-U++ applications.U++ supports following platforms on the production level: Windows, macOS, GNU/Linux &amp; FreeBSD.

Vivado Design Suite is a software suite designed by Xilinx for the design, synthesis and analysis of HDL for its line of FPGAs and SoCs. Vivado Design Suite includes many tools, like Vivado, Vitis, Vitis HLS and many others. This package provides a flatpak wrapper over an official installation. As the Xilinx tools are not redistributable, this package does not contain any Xilinx-licensed material, which is instead downloaded on-the-fly through the official Xilinx installer. To install it, install the flatpak package, then run any Xilinx launcher and follow the instructions. To uninstall, just remove the flatpak package to remove this wrapper. Note that this does not remove the Xilinx installation; to remove it, run the launcher "Uninstall Xilinx Design Tools or Devices" (or run "flatpak uninstall com.github.corna.Vivado --delete-data" to wipe everything in in "~/.var/app/com.github.corna.Vivado/").Why can't I see some of my files in Vivado? - All the Xilinx tools handled by this wrapper run in a sandbox with limited filesystem access, only your downloads, documents and desktop folders are visibile. Either work in those directories or override the default permission (with "flatpak override com.github.corna.Vivado --filesystem=&lt;path_here&gt;").I get an error "Can't open project [...]. Please verify that the project still exist.", why? - Same as before, make sure that the project is in one of the allowed folders.I have created a project outside Desktop or Documents: where are they? - You can find the sandboxed filesystem in "~/var/app/com.github.corna.Vivado/".I can not access the hardware devices. - Have you installed the "cable drivers" (which are just udev rules) at the end of the installation? To install them, run: "cd ~/.var/app/com.github.corna.Vivado/data/xilinx-install/Vivado/&lt;version&gt;/data/xicom/cable_drivers/lin64/install_script/install_drivers/ &amp;&amp; sudo ./install_drivers &amp;&amp; sudo udevadm control --reload", then re-connect any hardware device.Can I deny internet access to the Xilinx tools? - Yes, just remove the corresponding permission with: "flatpak override com.github.corna.Vivado  --unshare=network". Note that the license manager uses your MAC addresses, so you may experience issues with non free components.How can I install additional components? - Run the launcher "Add Xilinx Design Tools or Devices".Can I install an additional version of the Xilinx tools? - Yes, run "flatpak run --command=xilinx_install com.github.corna.Vivado".How can I remove a particular version? - Run the launcher "Uninstall Xilinx Design Tools or Devices".NOTE: This wrapper is not verified by, affiliated with, or supported by Xilinx, Inc.

      KCachegrind is a profile data visualization tool, used to determine the most time consuming parts in the execution of a program.
    
      Features:
      
        KCachegrind visualizes profiles (i.e. runtime characteristics) of applications in various ways,
          including call graph vizualisations and source/disassembler annotation.
        It can load profiles generated by the cache simulation/call tracer Calltree, a Valgrind tool.
          Thus, profiling does not need any preparation, can cope with shared libraries and plugin architectures, and does not influence the measuring itself.
        Converter scripts for OProfile, Perl, and PHP.
        Switching between multiple visualization layouts.
        Call graph can be exported as image (PNG).
        Simultaneous display of 2 event types in Call and Annotation View

This package contains Purr Data, which is a fork of Pure Data that bundles a lot of useful extensions, and brings a modern HTML5-based user interface.Pure Data is an open source visual programming environment that runs on anything from personal computers to embedded devices (ie Raspberry Pi) and smartphones (via libpd, DroidParty (Android), and PdParty (iOS). It is a major branch of the family of patcher programming languages known as Max (Max/FTS, ISPW Max, Max/MSP, etc), originally developed by Miller Puckette at IRCAM.Pd enables musicians, visual artists, performers, researchers, and developers to create software graphically without writing lines of code. Pd can be used to process and generate sound, video, 2D/3D graphics, and interface sensors, input devices, and MIDI. Pd can easily work over local and remote networks to integrate wearable technology, motor systems, lighting rigs, and other equipment. It is suitable for learning basic multimedia processing and visual programming methods as well as for realizing complex systems for large-scale projects.
