xPack LLVM clang v12.0.1-2 released
The xPack LLVM clang is a standalone cross-platform binary distribution of LLVM clang.
There are separate binaries for Windows (Intel 64-bit), macOS (Intel 64-bit, Apple Silicon 64-bit) and GNU/Linux (Intel 64-bit, Arm 32/64-bit).
The binary files are available from GitHub Releases.
- GNU/Linux Intel 64-bit: any system with GLIBC 2.27 or higher (like Ubuntu 18 or later, Debian 10 or later, RedHat 8 later, Fedora 29 or later, etc)
- GNU/Linux Arm 32/64-bit: any system with GLIBC 2.27 or higher (like Raspberry Pi OS, Ubuntu 18 or later, Debian 10 or later, RedHat 8 later, Fedora 29 or later, etc)
- Intel Windows 64-bit: Windows 7 with the Universal C Runtime (UCRT), Windows 8, Windows 10
- Intel macOS 64-bit: 10.13 or later
- Apple Silicon macOS 64-bit: 11.6 or later
The full details of installing the xPack LLVM clang on various platforms are presented in the separate Install page.
The easiest way to install LLVM clang is with
by using the binary xPack, available as
xpm tool available, installing
the latest version of the package and adding it as
a dependency for a project is quite easy:
cd my-project xpm init # Only at first use. xpm install @xpack-dev-tools/clang@latest ls -l xpacks/.bin
To install this specific version, use:
xpm install @firstname.lastname@example.org
It is also possible to install Meson Build globally, in the user home folder, but this requires xPack aware tools to automatically identify them and manage paths.
xpm install --global @xpack-dev-tools/clang@latest --verbose
To remove the links from the current project:
cd my-project xpm uninstall @xpack-dev-tools/clang
To completely remove the package from the global store:
xpm uninstall --global @xpack-dev-tools/clang
The xPack LLVM clang generally follows the official LLVM clang releases.
The current version is based on:
- LLVM clang version 12.0.1, from July 8th, 2021.
Compared to the upstream, there are no functional changes.
- 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.
On all platforms the packages are standalone, and expect only the standard runtime to be present on the host.
All dependencies that are build as shared libraries are copied locally
libexec folder (or in the same folder as the executable for Windows).
On GNU/Linux the binaries are adjusted to use a relative path:
$ readelf -d library.so | grep runpath 0x000000000000001d (RPATH) Library rpath: [$ORIGIN]
In the GNU ld.so search strategy, the
the highest priority, higher than
LD_LIBRARY_PATH, so if this later one
is set in the environment, it should not interfere with the xPack binaries.
Please note that previous versions, up to mid-2020, used
has a priority lower than
LD_LIBRARY_PATH, and does not tolerate setting
it in the environment.
Similarly, on macOS, the binaries are adjusted with
install_name_tool to use a
To save space and bandwidth, the original documentation is available online.
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:
For the prerequisites and more details on the build procedure, please see the README-MAINTAINER page.
Before publishing, a set of simple tests were performed on an exhaustive set of platforms. The results are available from:
The binaries were tested on a variety of platforms, but mainly to check the integrity of the build, not the compiler functionality.

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