Version 18.1.8-2 is a maintenance release; it fixes the missing coverage libraries on Windows.

The xPack LLVM clang is a standalone cross-platform binary distribution of LLVM clang.

There are separate binaries for Windows (x64), macOS (x64 and arm64) and GNU/Linux (x64, arm64 and arm).

Raspberry Pi

The main targets for the GNU/Linux Arm binaries are the Raspberry Pi class devices (armv7l and aarch64; armv6 is not supported).

Download​

The binary files are available from GitHub Releases.

Prerequisites​

  • x64 Windows: Windows 7 with the Universal C Runtime (UCRT), Windows 8, Windows 10, Windows 11
  • x64 macOS: 10.13 or later
  • arm64 macOS: 11.6 or later
  • x64 GNU/Linux: any system with GLIBC 2.27 or higher (like Ubuntu 18 or later, Debian 10 or later, RedHat 8 or later, Fedora 29 or later, etc)
  • arm64/arm GNU/Linux: any system with GLIBC 2.27 or higher (like Raspberry Pi OS, Ubuntu 18 or later, Debian 10 or later, RedHat 8 or later, Fedora 29 or later, etc)

Install​

The easiest way to install this specific version, is by using xpm:

xpm install @xpack-dev-tools/clang@18.1.8-2.1 -verbose

Comprehensive instructions for installing xPack LLVM clang on different platforms can be found in the Install Guide.

Compliance​

The xPack LLVM clang generally follows the official LLVM clang releases.

The current version is based on:

  • LLVM clang version 18.1.8, from 19 Jun 2024
  • binutils 2.42
  • mingw-w64 11.0.1

For x64 Linux and Windows, multilib (32/64-bit) libraries are provided.

Changes​

Compared to the upstream, there are no major functional changes.

Since 15.0.7-4, there is a small patch in Driver.cpp that fixes the function that computes InstalledDir when clang is invoked via a link from a different folder.

Documentation​

The original documentation is available from the project web site:

Build​

The binaries for all supported platforms (Windows, macOS and GNU/Linux) were built using the xPack Build Box (XBB), a set of build environments based on slightly older distributions, that should be compatible with most recent systems.

For the prerequisites and more details on the build procedure, please see the Maintainer Info page.

CI tests​

Before publishing, a set of simple tests were performed on an exhaustive set of platforms. The results are available from:

Tests​

The binaries were tested on a variety of platforms, but mainly to check the integrity of the build, not the compiler functionality.

Deprecation notices​

GNU/Linux minimum requirements​

The minimum requirement is GLIBC 2.27, available starting with Ubuntu 18, Debian 10 and RedHat 8. Support for RedHat 7 was dropped in 2022.

32-bit support​

Support for 32-bit x86 GNU/Linux and x86 Windows was dropped in 2022.

Pre-deprecation notice for 32-bit Arm GNU/Linux​

Due to the large user base of 32-bit Raspberry Pi systems, support for 32-bit Arm GNU/Linux (armv7l) will be preserved for a little while, but expect it to be dropped by 2025, so it is recommended to consider an upgrade to a RPi 4 or 5 with at least 4 GB (preferably 8 GB) of RAM.

Pre-deprecation notice for Ubuntu 18.04​

Ubuntu 18.04 LTS Bionic Beaver reached the end of the standard five-year maintenance window for Long-Term Support (LTS) release on 31 May 2023.

As a courtesy, the xPack GNU/Linux releases will continue to be based on Ubuntu 18.04 for another year.

From 2025 onwards, the GNU/Linux binaries will be built on Debian 10, (GLIBC 2.28), and are also expected to run on RedHat 8.

Users are urged to update their build and test infrastructure to ensure a smooth transition to the next xPack releases.
