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

Install clang-tools extra:

sudo dnf install clang-tools-extra

For Fedora < 32, you just need to install clang, which already bundles the clang-format tool.

sudo dnf install clang

And if you want to find the location of clang-format.You can use locate.

locate clang-format

Just build the Fedora37 package of clang locally :)

Install mock, add your user to the mock group, go to the RPM source page, i.e., https://src.fedoraproject.org/rpms/clang , click on clang-15 for F37, get the clang-15.0.0-2.fc37.src.rpm , and tell mock to build it in a container for your target architecture (assuming that is x86_64):

mock --config /etc/mock/fedora-36-x86_64.cfg --rebuild clang-15.0.0-2.fc37.src.rpm

Make yourself a coffee or two, and install the resulting rpms from the target directory you'll see at the very end of a successful run. (Hint: use cd /path/to/the/binary/rpms; sudo dnf install ./rpm1.rpm ./rpm2.rpm … to install them, satisfying dependencies as needed. You will need to install clang, libllvm and so on from that directory at once, to let dnf satisfy the dependencies.)

I don't think there is a really easy way to do this today, here are some details:

• clang comes installed on macOS and is the default compiler, but it does not come installed with clang-format or clang-tidy (or possibly any of the extra tools).
• It's really easy to use brew to install clang-format if you want it: brew install clang-format
• There is no clang-tidy brew formula.

As a result it seems like the best way to get clang-tidy on macOS is to simply install all of llvm and then make symlinks for the tools you want to use.

brew install llvm
ln -s "$(brew --prefix llvm)/bin/clang-format" "/usr/local/bin/clang-format"
ln -s "$(brew --prefix llvm)/bin/clang-tidy" "/usr/local/bin/clang-tidy"
ln -s "$(brew --prefix llvm)/bin/clang-apply-replacements" "/usr/local/bin/clang-apply-replacements"

Alternatively, you could download the prebuilt binaries and create the same symlinks. It's not a good idea to add all of llvm to your PATH because of conflicts with the default clang compiler.
