Set up Build Environment on Linux

Note: This is only a one-time setup guide. For actually building KeePassXC, please refer to our build guide.

Install the C++ toolchain

You can skip this step if you have a working C++ toolchain (g++, cmake and make)

On Debian/Ubuntu:

sudo apt install build-essential cmake g++

On Fedora/RHEL/CentOS:

sudo dnf install make automake gcc-c++ cmake 

On Arch Linux:

sudo pacman -S cmake make gcc

or

sudo pacman -S cmake make gcc-multilib

Install the required dependencies

On Debian/Ubuntu:

sudo apt install qtbase5-dev qttools5-dev qttools5-dev-tools \
    libgcrypt20-dev libargon2-0-dev libqrencode-dev zlib1g-dev

Ubuntu 14.04 and 16.04 require newer versions of libgcrypt20-dev, which can be installed from our Ubuntu PPA. To avoid clashes with the upstream libgcrypt20-dev package, our package is named libgcrypt20-18-dev and installs to /opt/keepassxc-libs/. You therefore need to set the following environment variables for CMake to find the required libraries:

export CMAKE_INCLUDE_PATH="/opt/keepassxc-libs/include"
export CMAKE_LIBRARY_PATH="/opt/keepassxc-libs/lib/x86_64-linux-gnu"

Alternatively, these can be passed as direct parameters to cmake later on (-DCMAKE_INCLUDE_PATH=... -DCMAKE_LIBRARY_PATH=...).

Ubuntu 14.04 is also missing the required libargon2-0-dev package, which can be installed from the same PPA.

On Fedora/RHEL/CentOS:

sudo dnf install qt5-qtbase-devel qt5-linguist qt5-qttools \
    libgcrypt-devel libargon2-devel qrencode-devel zlib-devel

CentOS requires more up-to-date packages, provided here: https://copr.fedorainfracloud.org/coprs/bugzy/keepassxc/

On Arch Linux:

sudo pacman -S qt5-base qt5-tools libgcrypt argon2 qrencode zlib

Install the optional dependencies

These are required to build Auto-Type, Yubikey and browser integration support.

On Debian/Ubuntu:

sudo apt install libxi-dev libxtst-dev libqt5x11extras5-dev \
    libyubikey-dev libykpers-1-dev libsodium-dev libcurl4-openssl-dev

For Ubuntu 14.04, the libsodium-dev package is provided through our PPA, see above.

On Fedora/RHEL/CentOS:

sudo dnf install libXi-devel libXtst-devel qt5-qtx11extras \
    qt5-qtx11extras-devel libyubikey-devel ykpers-devel \
    libsodium-devel libcurl-devel

CentOS requires more up-to-date packages, provided here: https://copr.fedorainfracloud.org/coprs/bugzy/keepassxc/

On Arch Linux:

sudo pacman -S libxi libxtst qt5-x11extras qt5-tools \
    yubico-c yubikey-personalization libsodium curl

Update your environment regularly

On Debian/Ubuntu:

sudo apt-get update && sudo apt-get upgrade

On Fedora/RHEL/CentOS:

sudo dnf update && sudo dnf upgrade

On Arch Linux:

sudo pacman -Syyuu
