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. 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.
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!
