NAME

dpkg-depcheck - determine packages used to execute a command  

SYNOPSIS

dpkg-depcheck [options] command  

DESCRIPTION

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.  

OPTIONS

-a, --all
Report all packages used to run command. This is the default behaviour.
-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 finally reported.
--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.
-h, --help
Display usage information and exit.
-v, --version
Display version and copyright information and exit.
 

CONFIGURATION VARIABLES

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!
