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!
