dpkg-depcheck - determine packages used to execute a command
dpkg-depcheck [options] command
This program runs the specified command under strace and then determines and outputs the packages used in the process. The list can be trimmed in various ways as described in the options below. A good example of this program would be the command dpkg-depcheck -b debian/rules build, which would give a good first approximation to the Build-Depends line needed by a Debian package. Note, however, that this does not give any direct information on versions required or architecture-specific packages.
-a, --all Report all packages used to run command. This is the default behaviour. If used in conjunction with -b, -d or -m, gives additional information on those packages skipped by these options. -b, --build-depends Do not report any build-essential or essential packages used, or any of their (direct or indirect) dependencies. -d, --ignore-dev-deps Do not show packages used which are direct dependencies of -dev packages used. This implies -b. -m, --min-deps Output a minimal set of packages needed, taking into account direct dependencies. Using -m implies -d and also -b. -C, --C-locale Run command with the C locale. --no-C-locale Don't change locale when running command. -l, --list-files Also report the list of files used in each package. --no-list-files Do not report the files used in each package. Cancels a -l option. -o, --output=FILE Output the package diagnostics to FILE instead of stdout. -O, --strace-output=FILE Write the strace output to FILE when tracing command instead of using a temporary file. -I, --strace-input=FILE Get strace output from FILE instead of tracing command; strace must have be run with the -f -q options for this to work. -f, --features=LIST Enable or disabled features given in the comma-separated LIST as follows. A feature is enabled with +feature or just feature and disabled with -feature. The currently recognised features are: warn-local Warn if files in /usr/local or /var/local are used. Enabled by default. discard-check-version Discards execve when only a --version argument is given to the program; this works around some configure scripts that check for binaries they don't actually use. Enabled by default. trace-local Also try to identify files which are accessed in /usr/local and /var/local. Not usually very useful, as Debian does not place files in these directories. Disabled by default. catch-alternatives Warn about access to files controlled by the Debian alternatives mechanism. Enabled by default. discard-sgml-catalogs Discards access to SGML catalogs; some SGML tools read all the registered catalogs at startup. Files matching the regexp /usr/share/sgml/.*\.cat are recognised as catalogs. Enabled by default. --no-conf, --noconf Do not read any configuration files. This can only be used as the first option given on the command-line. -h, --help Display usage information and exit. -v, --version Display version and copyright information and exit.
The two configuration files /etc/devscripts.conf and ~/.devscripts are sourced in that order to set configuration variables. Command line options can be used to override configuration file settings. Environment variable settings are ignored for this purpose. The currently recognised variable is: DPKG_DEPCHECK_OPTIONS These are options which are parsed before the command-line options. For example, DPKG_DEPCHECK_OPTIONS="-b -f-catch-alternatives" which passes these options to dpkg-depcheck before any command-line options are processed. You are advised not to try tricky quoting, because of the vagaries of shell quoting!
