fortdep

Tool to generate dependencies for Modern Fortran programs.

Version 1 and 2

Package comes with two scripts: fortdep which is the original version, kept for compatibility, and fortdep2 which is currently developed version. Expect that in the future the latter will be renamed to fortdep.

Installation

In virtual environment:

python3 setup.py install

For current user:

python3 setup.py install --user

Usage

usage: fortdep2 [-h] [--programs] [--no-includes] [--scaffold] [--verbose]
                [--encoding ENCODING] [--output OUTPUT]
                [path [path ...]]

positional arguments:
  path

optional arguments:
  -h, --help            show this help message and exit
  --programs, -p        generate rules to link programs
  --no-includes, -i     don't generate dependencies from includes
  --scaffold, -s        generate entire makefile
  --verbose, -v         more info
  --encoding ENCODING, -e ENCODING
                        specify input encoding (default: utf-8)
  --output OUTPUT, -o OUTPUT
                        write output to file

Example 0

Just display the dependencies on screen:

fortdep2

Example 1

Typical use is to generate dependencies and write them in a file

fortdep2 -o deps.inc

which is then included in Makefile:

include deps.inc

Example 2

Generate whole Makefile (it is assumed that all Fortran sources have .f90 extension):

fortdep2 -s -o Makefile

Problems and bugs

Encoding

Most contemporary Linux systems use utf-8 encoding. If you run across the error similar to below, please use -e option to specify input encoding.

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xbf in position 16: invalid start byte
