Installation

contour is packaged and available for installation on multiple distributions.

sudo dnf install contour-terminal

Installing via Flatpak

Install from Flathub

Click the following button install Contour from the Flathub store.

Get it on Flathub

Prerequisites

Requirements

  • operating system: A recent operating system (OS/X 12, Windows 10+, an up-to-date Linux, or FreeBSD)
  • GPU: driver must support at least OpenGL 3.3 hardware accelerated or as software rasterizer.
  • CPU: x86-64 AMD or Intel with AES-NI instruction set or ARMv8 with crypto extensions.

Configuration

In order to set up Contour, it is necessary to modify the configuration file contour.yml, which is initially generated in the $HOME/.config/contour directory. Some features also require shell integration. These can be generated via the CLI (see below), these currently exist for zsh, fish and tcsh.

Installing from source

Contour is best installed from supported package managers, but you can build from source by following the instruction below. You can Qt 5 or Qt 6, by default contour will be compiler with Qt 6, to change Qt version use QTVER=5 ./scripts/install-deps.sh to fetch dependencies and cmake flag -D CONTOUR_QT_VERSION=5.

UNIX-like systems (Linux, FreeBSD, OS/X)

Prerequisites

./scripts/install-deps.sh

This script might ask you for the administrator password if a package dependency can be insalled via the system package manager.

Compile

cmake -S . -B build -G Ninja
cmake --build build/

# Optionally, if you want to install from source
cmake --build build/ --target install

Windows 10 or newer

Prerequisites

For Windows, you must have Windows 10, 2018 Fall Creators Update, and Visual Studio 2019, installed. It will neither build nor run on any prior Windows OS, due to libterminal making use of ConPTY API.

  1. Set up vcpkg, preferably somewhere high up in the folder hierarchy, and add the folder to your PATH.
cd C:\
git clone git clone https://github.com/Microsoft/vcpkg.git
.\vcpkg\bootstrap-vcpkg.bat
  1. Install Visual Studio Build Tools (make sure to select the CLI tools for C++, which you might need to do in the separate components tab).
  2. Install Qt6 (i.e. to C:\Qt)
  3. Open the developer version of Powershell.
  4. In the contour source folder execute .\scripts\install-deps.ps1. This step may take a very long time.

Compile

In the developer version of Powershell:

# change paths accordingly if you installed QT and vcpkg to somewhere else
cmake -S . -B build -DCMAKE_TOOLCHAIN_FILE=C:\vcpkg\scripts\buildsystems\vcpkg.cmake -DCMAKE_PREFIX_PATH=C:\Qt\6.5.0\msvc2019_64\lib\cmake
cmake --build build/

# Optionally, if you want to install from source
cmake --build build/ --target install
