## プロジェクトの歴史と使われ方

ftnchek is a Fortran 77 static analyzer and program checker. Its official documentation describes it as a tool for finding semantic errors, portability problems, questionable declarations, unused variables, and related issues that a compiler may not diagnose.

### プロジェクトの歴史

The project is maintained from Robert K. Moniot's Fordham University pages, where version 3.3 is documented as the latest major release and version 3.3.1 source and binaries were published in February and March 2005. The project later added a SourceForge presence for development work, with the homepage directing contributors to the SourceForge CVS repository for the most recent experimental source.

### 採用の歴史

The official download area distributed source archives, Unix manual formats, PostScript and PDF documentation, and binaries for Windows, Linux, Solaris, and Mac OS X. The project page also pointed users toward long-running scientific-software distribution channels such as Netlib and ibiblio.

### 使われ方

ftnchek is used before or alongside compilation to inspect legacy Fortran code for semantic and portability problems. The companion dcl2inc utility and the large option set reflect the needs of maintaining old Fortran codebases across different compilers and platforms.

### パッケージ好きにとっての重要性

For package maintainers, ftnchek is a classic example of a small, long-lived language-specific checker whose upstream release tarball, generated manuals, and platform binaries predate modern forge workflows but remain useful for scientific and engineering code archaeology.

### タイムライン

- 2004: FTNCHEK 3.3 manual updated in November 2004.
- 2005: Status page lists ftnchek 3.3 and describes new Fortran 90 pointer-syntax support.
- 2005: Version 3.3.1 source, documentation, and several platform binaries published.
- 2006: Official download area adds a patch for the 3.3.1 variable-format parsing bug.

### Related projects

- dcl2inc is distributed with ftnchek documentation as a related utility.
- ftnpp is listed by the official download page as an auxiliary preprocessor for code using both cpp-style and Fortran INCLUDE directives.
- The official homepage links to a Fortran 90 volunteer effort, reflecting interest in extending ftnchek beyond its Fortran 77 base.
