Easy install

The easiest way to install LLVM clang is using the binary xPack, available as @xpack-dev-tools/clang from the npmjs.com registry.


The only requirement is a recent xpm, which is a portable Node.js command line application. To install it, follow the instructions from the xpm page.


With the xpm tool available, installing the latest version of the package is quite easy:

cd my-project
xpm init # Only at first use.

xpm install @xpack-dev-tools/clang@latest

ls -l xpacks/.bin

This command will:

  • install the latest available version, into the central xPacks store, if not already there
  • add symbolic links (.cmd forwarders on Windows) into the local xpacks/.bin folder to the central store

The central xPacks store is a platform dependent folder; check the output of the xpm command for the actual folder used on your platform). This location is configurable via the environment variable XPACKS_REPO_FOLDER; for more details please check the xpm folders page.

xPacks aware tools automatically identify binaries installed with xpm and provide a convenient method to manage paths.


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

Manual install

For all platforms, the xPack LLVM clang binaries are released as portable archives that can be installed in any location.

The archives can be downloaded from the GitHub Releases page.

For more details please read the Install page.


The version strings used by the LLVM project are three number string like 12.0.1; to this string the xPack distribution adds a four number, but since semver allows only three numbers, all additional ones can be added only as pre-release strings, separated by a dash, like 12.0.1-1. When published as a npm package, the version gets a fifth number, like 12.0.1-1.1.

Since adherance of third party packages to semver is not guaranteed, it is recommended to use semver expressions like ^12.0.1 and ~12.0.1 with caution, and prefer exact matches, like 12.0.1-1.1.
