Version 14.0.6-2 is a maintenance release; it includes a patch to fix a clangd issue.

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

There are separate binaries for Windows (x64), macOS (x64, 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 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)
  • x64 Windows: Windows 7 with the Universal C Runtime (UCRT), Windows 8, Windows 10
  • x64 macOS: 10.13 or later
  • arm64 macOS: 11.6 or later

Install​

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

xpm install @xpack-dev-tools/clang@14.0.6-2.1 -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 14.0.6, from 25 Jun 2022.

Changes​

Compared to the upstream, there are no functional changes.

Bug fixes​

  • [#3]: clangd 14.0.6 had a bug (1072), fixed in 15.0.0; the fix was cherry picked and the bug fixed.

Enhancements​

  • none

Known problems​

  • on GNU/Linux, support for the clang run-time and C++ libraries is basic, the libraries are available, but using them is tricky, since it requires the compiled binaries to take care of the path to them, otherwise it is very likely that the system libraries will be used; thus it is recommended to avoid such use cases.
  • when clang is invoked via a link from a different folder, the InstalledDir does not reflect the correct install folder, and the new clang system headers are either not found or the host system headers are used; fixed in 15.0.7-4
  • on macOS, the /Library/Developer/CommandLineTools/usr/include/c++/v1 was added to the include path; unfortunately this may crash some builds; removed in 15.0.7-3

Documentation​

The original documentation is available online.

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.

The scripts used to build this distribution are in:

  • distro-info/scripts

For the prerequisites and more details on the build procedure, please see the README-MAINTAINER 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​

32-bit support​

Support for 32-bit x86 GNU/Linux and x86 Windows was dropped in 2022. Support for 32-bit Arm GNU/Linux (armv7l) will be preserved for a while, due to the large user base of 32-bit Raspberry Pi systems.

GNU/Linux minimum requirements​

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