clang-tidy install

Question

I have clang installed from packages on both Ubuntu 14.07, Centos 7 and Fedoara 22. I would like to use clang-tidy but can neither find a package nor how to install it without installing clang from source. That's something I would rather not do.

What am I missing?

I might be dense, if so please mock me.

Solution 1

You can use your package manager to find out which package clang-tidy provides. For example on Fedora/CentOS:

dnf whatprovides '*/clang*tidy*'

On Debian/Ubuntu you can use an analogous apt-file search command.

However, on Fedora 23 clang-tidy just isn't packaged. No match is found.

There is even an open bug report: Missing clang-query and clang-tidy

For Ubuntu/Debian, the LLVM project maintains an llvm apt repostiory. This should be the easiest way to get the latest clang-tidy. After configuring that repository and doing an apt-file update and apt-file search should return the package that provides clang-tidy.

An alternative to building from source is to use the upstream llvm pre-built binaries - they are available for Fedora, CentOS etc. For example the one for Fedora 23 does contain clang-tidy:

clang+llvm-3.8.0-x86_64-fedora23/bin/clang-tidy

Solution 2

Fedora 29 includes clang-tidy in the main Fedora repository. You can install it via:

dnf install clang-tools-extra
