NAME¶
Edos-builddebcheck - Check satisfiability of Debian package build-dependencies
SYNOPSIS¶
edos-builddebcheck [option] ... Packagefile Sourcepackagefile
DESCRIPTION¶
edos-builddebcheck reads a set of Debian package descriptions from the
file
Packagefile, each of which is in the format of
deb-control(5), and
a set of source package descriptions from the file
Sourcepackagefile.
All packages described in the file
Packagefile must have the same value
of their
Architecture (if it is different from
all).
For instance, the Packages and Sources files as found on a Debian mirror server,
or in the directory
/var/lib/apt/lists/ of a Debian system, are
suitable as input files.
edos-builddebcheck verifies for every of the source packages (from
Sourcepackagefile) whether its build-dependencies,
build-indep-dependencies and build-conflicts can be satisfied from the binary
packages provided in
Packagefile. Only build-relations that apply to
the architecture (see below on how the architecture is determined) are taken
into account.
Note that this is not the same thing as checking whether a distribution can be
rebuild from scratch, for several reasons:
1. No actual compilation is taking place, this tool only does a static
analysis of package relationships.
2. The binary packages in
Packages are not necessarily those that
are the result of the compilation of the source packages in
Sourcepackagefile.
3. We do not check for cycles. For instance, suppose that we have source
packages
a and
b both generating one binary package of
respectively the same name, and that
a build-depends on
b and
b build-depends on
a. Then we can not rebuild the set of
packages from scratch because of the cycle. However, if we already have binary
packages
a and
b then we can recompile both of them.
Consequently,
edos-builddebcheck will not report an error in this case.
4. The underlying logical machine does a complete analysis of
alternatives, and might report satisfiability of constraints in case actual
tools (like apt) fail to find a solution.
Build-essential packages are ignored in unversioned build-dependencies. The
(architecture dependant) list of build-essential packages is read from the
configuration file. If that file is not available than an architecture
independent default value is used.
OPTIONS¶
- -a, --architecture architecture
- Check for compilation on architecture. Usually it is
not necessary to specify the architecture since it can be derived from the
Packages file.
- -be, --binexplain
- Add all explanations why build-dependencies are not
satisfiable. Without that option some of these explanations may be missing
from the output in case a source package build-depends on a binary package
that exists in Packagefile file but that edos-debchecks finds not
to be installable inside Packagefile.
FILES¶
- /etc/edos-builddebcheck.conf
- Configuration file for edos-builddebcheck
