How To Fix c2xml: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu c2xml is provided by sparse package.

sparse is:

Sparse, the semantic parser, provides a compiler frontend capable of parsing most of ANSI C as well as many GCC extensions, and a collection of sample compiler backends, including a static analyzer also called “sparse”. Sparse provides a set of annotations designed to convey semantic information about types, such as what address space pointers point to, or what locks a function acquires or releases.

Sparse can be invoked directly as “sparse” or via the “cgcc” wrapper around the C compiler.
