Fixing Broken C/C++ Tooling on Ubuntu

Here we're assuming you want to have gcc versions 13 & 14 and clang versions 16 & 17 installed side by-side. Adjust to the versions you're installing.

You may also wish to adjust the priority (the last number in the update-alternatives commands below). A higher number means a higher priority.

TLDR;

Check for env::var("DOCS_RS") in your build.rs and omit linking if it is set.

Where to find this: read the complete About section on docs.rs.
