Build Kùzu from source

Note

This page is intended for developers who want to build Kùzu from source. If you are a user of Kùzu, please refer to the installation guide for downloading pre-built binaries for your platform.

To build from source code, Kùzu requires CMake(>=3.15), Python(>=3.9), and a compiler that supports C++20. The minimum supported version of C++ compilers is GCC 11, Clang 12, and MSVC 19.20. The preferred compiler on Linux is GCC; on macOS, Apple Clang; and on Windows, MSVC. On Linux, Clang is also tested. Other compilers which support C++20 may also work, but are not tested.

Below are the instructions for building Kùzu on Ubuntu 22.04 LTS, AlmaLinux 9.2, Arch Linux, macOS 12, and Windows 10. These instructions should also work for other similar platforms:

• For other Debian-based Linux distros, such as Debian, Linux Mint, and Pop!_OS, the instructions should be similar to Ubuntu 22.04 LTS.
• For other Red Hat-based Linux distros, such as Red Hat Enterprise Linux (RHEL), CentOS, Fedora, Rocky Linux, and Oracle Linux, the instructions should be similar to AlmaLinux 9.2.
• For other Arch-based Linux distros, such as Manjaro, the instructions should be similar to Arch Linux.
• For other versions of macOS, the instructions should be similar to macOS 12.
• For other versions of Windows, the instructions should be similar to Windows 10.

For additional information regarding the tests, please refer to the documentation for Testing Framework.

Increase ulimit for running tests

For some platforms, such as macOS, the default limit for the number of open files is too low for running tests, which may cause some tests to fail. To increase the limit, please run the following command before running tests.

ulimit -n 10000
