PROGRAM:

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.

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


OPTIONS FOR SPECIFYING ARCHITECTURES
--deb-native-arch=name
Specify the native architecture. This argument is mandatory.

--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-host-arch=name...
Specify the host architecture.

OPTIONS FOR FILTERING THE INPUT
--latest
Only the latest version of each package is kept, older versions of packages are
ignored.

OPTIONS CONTROLLING OUTPUT
-f --failures
Only show broken packages that fail the installability check.

-s --successes
Only show packages that do not fail the installability check.

-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.

-o file Send output to file.

MISC OPTIONS
-v Enable info / warnings / debug messages. This option may be repeated up to three
times in order to increase verbosity.

-h, --help
Display this list of options.

--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.

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 --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:

deb-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
