NAME

dose-builddebcheck - Check if a package can be built on a Debian system

SYNOPSIS

dose-builddebcheck --deb-native-arch=name [options] binary-repositories source-repository

DESCRIPTION

dose-builddebcheck determines, for a set of debian source package control stanzas, called the source repository, whether a build environment for the packages of the source repository can be installed on the specified native architecture by using packages from the binary repository. For this, only package meta-information is taken into account: build-dependencies and build-conflicts in the source package, and inter-package relationsships expressed in the binary repository. The constraint solving algorithm is complete, that is it finds a solution whenever there exists one, even for multiple disjunctive dependencies and deep package conflicts. This problem is computationally infeasible in theory (that is, NP-complete), but can be solved very efficiently for package repositories that actually occur in practice. Installability of binary packages is analyzed according to their Depends, Conflicts, and Provides fields with their meaning as of Debian policy version 3.9.0. Pre-depends are treated like Depends, and Breaks are treated like Conflicts.

INPUT FORMAT

The binary-repositories argument is a list of filenames containing stanzas in the format of deb-control(5), separated by one blank line. For instance, the Packages files as found on a Debian mirror server, or in the directory /var/lib/apt/lists/ of a Debian system, are suitable. The source-repository argument is the name of a file containing debian source control stanzas, separated by one blank line. For instance, the Sources files as found on a Debian mirror server, or in the directory /var/lib/apt/lists/ of a Debian system, are suitable. binary-repositories and source-repository can be passed in compresssed format (.gz , .bz2).

Multi-arch annotations are correctly considered by dose-builddebcheck. Packages whose's architecture is neither the native architecture nor in the list of foreign architectures (see below) are ignored. Here, native and foreign refers at the same time to the architecture on which the compilation will be run, and to the host architecture of the compilation. Cross-compilation is supported by specifying the host architecture.

OPTIONS

MISC OPTIONS

--version: Show program's version and exit.
-h, --help: This option displays the help message.
-v, --verbose: Enable info / warnings / debug messages. This option may be repeated up to three times in order to increase verbosity.
--progress: Print progress bars.
--timers: Print timing information.
--quiet: Do no print any messages.

DISTCHECK OPTIONS

-e, --explain: Give explanations. If used together with --failures then the explanation consists of dependency chains leading to a conflict or a dependency on a missing package. If used together with --successes then the explanation consists of an installation set.
-m, --explain-minimal: For all packages P that are found installable, and when used in conjunction with --successes, prints a reduced installation set containing only those packages in the dependency cone of P. When used with Debian repositories, all essential packages and their dependencies that are not in the cone of P are omitted. When used in conjunction with --failures, and --explain, all dependencies chains are not printed.
-c, --explain-condense: Compress explanation graph
-f --failures: Only show broken packages that fail the installability check.
-s --successes: Only show packages that do not fail the installability check.
--summary: Gives a more detailed summary of the findings.

INPUT OPTIONS

--checkonly package [,package] ...: Takes a comma-separated list of package names, each of them possibly with a version constraint, as argument. The foreground is constituted of all packages that match any of the expressions, all other packages are pushed into the background. The initial distinction between foreground and background is ignored. This option must not be combined with --coinst.
Example: --checkonly "libc6 , 2ping (= 1.2.3-1)"
--latest n: Consider only the latest -n most recent versions of each package, older versions of packages are ignored.

OUTPUT OPTIONS

-o, --outfile= file: Send output to file.
-d, --outdir= directory: Set the output directory (default current directory).
--dot: Save the explanation graph (one for each package) in dot format.
--dump=file: Dump the cudf file.

DEBIAN OPTIONS

--deb-native-arch=name: Specify the native architecture. This argument is mandatory.
--deb-host-arch=name...: Specify the host architecture.
--deb-foreign-archs=name [,name] ...: Specify a comma-separated list of foreign architectures. The default is an empty list of foreign architectures. If --deb-host-arch is set, it is used as an implicit foreign architecture.
--deb-ignore-essential: Do not consider essential packages as part of the installation problem. By default all essential package are considered as part of the installation problem for all packages, that is a package is installable if and only if it is co-installable with all essential packages. This option allows the user to test the installability with no essential packages installed.
--deb-builds-from: Add builds-from relationship of binary packages on source packages as dependency. This allows one to create graphs for bootstrapping purposes.
--deb-tupletable=file: Path to an architecture tuple table like /usr/share/dpkg/tupletable
--deb-cputable=file: Path to a cpu table like /usr/share/dpkg/cputable
--deb-defaulted-m-a-foreign: Convert Arch:all packages to Multi-Arch: foreign
--deb-drop-b-d-indep: Drop Build-Indep dependencies
--deb-drop-b-d-arch: Drop Build-Arch dependencies
--deb-include-extra-source: Include packages with Extra-Source-Only:yes (dropped by default)
-P, --deb-profiles=name[,name...]: Comma separated list of activated build profiles.
--deb-emulate-sbuild: Replicate sbuild behaviour to only keep the first alternative of build dependencies.

EXIT CODES

Exit codes 0-63 indicate a normal termination of the program, codes 64-127 indicate abnormal termination of the program (such as parse errors, I/O errors).

In case of normal program termination:

- exit code 0 indicates that all foreground packages are found installable;

- exit code 1 indicates that at least one foreground package is found uninstallable.

EXAMPLE

Compute the list of source packages in Sources for which it is not possible to install a build environment on i386, assuming that the binary packages described in file Packages are available:

 dose-builddebcheck -v -f -e --deb-native-arch=amd64 \
 /var/lib/apt/lists/ftp.fr.debian.org_debian_dists_sid_main_binary-amd64_Packages\
 /var/lib/apt/lists/ftp.fr.debian.org_debian_dists_sid_main_source_Sources

Compute the list of source packages for armel in Sources for which it is not possible to install a mix build environment on amd64 plus armel, assuming that the binary packages described in file Packages are available:

 dose-builddebcheck --failures --successes --deb-native-arch=amd64 \
 --deb-foreign-archs=armel,linux-any --deb-host-arch=armel \
 DebianPackages/Sid-amd64-armel-Packages-050812.bz2 
 DebianPackages/Sid-Sources-single-version-050812.bz2

AUTHOR

The current version has been rewritten on the basis of the dose3 library by Pietro Abate; it replaces an earlier version that was simply a wrapper for edos-distcheck.
