fortdepend: A Fortran Dependency Generator

fortdepend is a python package to automatically generate Fortran dependencies.

Given a set of files, fortdepend automatically constructs the dependency graph for the programs and files and can write a dependency file suitable for Makefiles. fortdepend now uses pcpp, a preprocessor written in Python, so it can determine which modules will actually be used when you compile.

You can even use fortdepend to draw the graph of the module dependencies (requires graphviz)!

Original script by D. Dickinson


  • fortdepend requires Python 3.
  • fortdepend works by looking for matching pairs of program <name>/end program <name> and module <name>/end module <name>, and so will not work on Fortran 77-style files that just use end without the appropriate label.
