2.21 Dependency Analysis

The dependency analyser takes a set of Fortran source files and produces dependency information in the form specified. C files and fpp-processed files are not handled.

The dependency analyser understands the following compiler options with the same meaning: -132, -dryrun, -english, -fixed, -free, -help, -I, -indirect, -maxcontin, -nihongo, -o, -Qpath, -tempdir, -v and -V. The “@filename” syntax may also be used with the same effect as the “-indirect filename” option.

The following additional options control the operation of the dependency analyser:

-otype=type
This option controls the output form, type must be one of:

blist (the filenames as an ordered build list),
dfile (the dependencies in Makefile format, written to separate file.d files),
info (the dependencies as English descriptions) or
make (the dependencies in Makefile format).

The default is -otype=info. If -otype=dfile is specified, no -o option is permitted; otherwise, the result is written to the file specified by the -o option or to standard output if no -o option is specified.

-paths=pathtype
Specifes the form to use for dependency paths; pathtype must be either absolute or relative. With -paths=absolute, paths for INCLUDE files that are relative specifications will be prefixed by the current working directory.
