history
Project history and usage
mcpp is a portable C/C++ preprocessor and validation suite by Kiyoshi Matsui. The official site describes it as an independent preprocessor that implements C90, C99, and C++98 preprocessing behavior, provides diagnostics, and can be built as a compiler-specific preprocessor, a compiler-independent command, or a subroutine library.
Project history
The project was created to address portability and conformance problems in traditional compiler-bundled preprocessors. Its official homepage says mcpp was selected for Japan IPA's Exploratory Software Projects in both 2002 and 2003.
The public SourceForge-hosted project surface dates from April 2006, and the official homepage lists V.2.7.2 from November 2008 as the latest release.
Adoption history
mcpp was packaged both as upstream binary archives and by operating-system distributions. The official download page documents FreeBSD, Linux RPM and deb, Mac OS X, and Windows packages, and separately notes distribution packages for Fedora, Debian, Ubuntu, OpenSUSE, Gentoo, Slackware, and MacPorts.
Distribution packaging split the executable, shared library, development files, and documentation on Fedora and Debian-family systems, which made mcpp useful as a reusable compiler-toolchain component rather than only as a standalone command.
How it is used
The command-line program is installed as `mcpp`. The official download page points users to the bundled manual and explains that source archives include source code, a validation suite, and English and Japanese documentation.
Typical package-manager usage is installing a small preprocessor tool or library for C/C++ toolchains, conformance testing, macro debugging, or historical build compatibility.
Why package nerds care
mcpp matters to package nerds because it is a small compiler component that was packaged independently of a full compiler. Its history includes classic Unix packaging patterns: source tarballs, RPMs, debs, ports, a shared library package, development headers, and documentation packages.
It is also a useful example of an important package whose official presence is an old project homepage and release archive rather than a modern canonical Git repository.
