Compiling from source

Note: Arch Linux users can simply install quickcurver-git from the AUR:

yay -S quickcurver-git


First make sure, that you have the required dependencies of QuickCurver installed. These are:

  • A C++ compiler with C++14 support
  • make
  • At least Qt 5.12
  • The following Qt Modules (in the parantheses there is an example how the package could be called for your distro (this depends on the distro!)):
    • Qt Core (qt5-base)
    • Qt GUI (qt5-base)
    • Qt Quick (qt5-declarative)
    • Qt QML (qt5-declarative)
    • Qt SVG (qt5-svg)
    • Qt Network (qt5-base)
    • Qt Quick Controls 2 (qt5-quickcontrols2)
    • Qt Graphical Effects (qt5-graphicaleffects)

Build instructions

Run the following commands:

git clone --recursive
# Alternatively clone with HTTPS, if you don't have SSH keys
# If you forgot to clone with --recursive, just run git submodule update --init
cd quickcurver
mkdir build
cd build
qmake ..

To start QuickCurver you need to run the built executable in the build/src directory, for example on Linux run: src/QuickCurver

Installing compiled binaries


When you click on the AppVeyor icon or go to directly, you can click on Artifacts on the latest build and download a zip file. Extract all files and run QuickCurver.exe in the release directory.


Note: The multiplayer is not 100% stable yet.

To play multiplayer, the host starts an instance and shares the port that QuickCurver is running on. The client then just has to connect to this port on the host's ip address. If you are not in the same local network, the host most likely has to use Port Forwarding to make his device available to the internet. If a firewall is the problem, you might also want to take a look at Hole Punching.

If network performance isn't good, the Server can tweak the "Network update rate" value in the settings, which causes data to be sent less frequently which may improve the network performance at the cost of update frequency. (A higher value means worse quality, but better network performance)

If you want to host Quickcurver on a separate server and do not need the GUI, you can start it with the CLI parameter -platform offscreen.

You can’t perform that action at this time.
