NAME         top

       deb-buildinfo - Debian build information file format

SYNOPSIS         top


DESCRIPTION         top

       Each Debian source package build can record the build information in
       a .buildinfo control file, which contains a number of fields.  Each
       field begins with a tag, such as Source or Binary (case insensitive),
       followed by a colon, and the body of the field.  Fields are delimited
       only by field tags.  In other words, field text may be multiple lines
       in length, but the installation tools will generally join lines when
       processing the body of the field (except in case of the multiline
       fields Binary-Only-Changes, Installed-Build-Depends, Environment,
       Checksums-Md5, Checksums-Sha1 and Checksums-Sha256, see below).

       The control data might be enclosed in an OpenPGP ASCII Armored
       signature, as specified in RFC4880.

       The name of the .buildinfo file will depend on the type of build and
       will be as specific as necessary but not more; for a build that
       includes any the name will be source-name_binary-
       version_arch.buildinfo, or otherwise for a build that includes all
       the name will be source-name_binary-version_all.buildinfo, or
       otherwise for a build that includes source the name will be source-

FIELDS         top

       Format: format-version (required)
              The value of this field declares the format version of the
              file.  The syntax of the field value is a version number with
              a major and minor component.  Backward incompatible changes to
              the format will bump the major version, and backward
              compatible changes (such as field additions) will bump the
              minor version.  The current format version is 1.0.

       Source: source-name [(source-version)] (required)
              The name of the source package.  If the source version differs
              from the binary version, then the source-name will be followed
              by a source-version in parenthesis.  This can happen when the
              build is for a binary-only non-maintainer upload.

       Binary: binary-package-list (required)
              This folded field is a space-separated list of binary packages

       Architecture: arch-list (required)
              This space-separated field lists the architectures of the
              files currently being built.  Common architectures are amd64,
              armel, i386, etc.  Note that the all value is meant for
              packages that are architecture independent.  If the source for
              the package is also being built, the special entry source is
              also present.  Architecture wildcards must never be present in
              the list.

       Version: version-string (required)
              Typically, this is the original package's version number in
              whatever form the program's author uses.  It may also include
              a Debian revision number (for non-native packages).  The exact
              format and sorting algorithm are described in deb-version(7).

              This multiline field contains the concatenated text of the
              changelog entry for a binary-only non-maintainer upload
              (binNMU) if that is the case.  To make this a valid multiline
              field empty lines are replaced with a single full stop (‘.’)
              and all lines are indented by one space character.  The exact
              content depends on the changelog format.

       Checksums-Md5: (required)
       Checksums-Sha1: (required)
       Checksums-Sha256: (required)
        checksum size filename
              These multiline fields contain a list of files with a checksum
              and size for each one.  These fields have the same syntax and
              differ only in the checksum algorithm used: MD5 for
              Checksums-Md5, SHA-1 for Checksums-Sha1 and SHA-256 for

              The first line of the field value (the part on the same line
              as the field name followed by a colon) is always empty.  The
              content of the field is expressed as continuation lines, one
              line per file.  Each line consists of space-separated entries
              describing the file: the checksum, the file size, and the file

              These fields list all files that make up the build.

       Build-Origin: name
              The name of the distribution this package is originating from.

       Build-Architecture: arch (required)
              The Debian architecture for the installation the packages is
              being built in.  Common architectures are amd64, armel, i386,

       Build-Date: build-date
              The date the package was built.  It must be in the same format
              as the date in a deb-changelog(5) entry.

       Build-Kernel-Version: build-kernel-version
              The release and version (in an unspecified format) of the
              kernel running on the build system.  This field is only going
              to be present if the builder has explicitly requested it, to
              avoid leaking possibly sensitive information.

       Build-Path: build-path
              The absolute build path, which correspond to the unpacked
              source tree.  This field is only going to be present if the
              vendor has whitelisted it via some pattern match to avoid
              leaking possibly sensitive information.

              On Debian and derivatives only build paths starting with
              /build/ will emit this field.

       Installed-Build-Depends: (required)
              The list of installed and configured packages that might
              affect the package build process.

              The list consists of each package name, optionally arch-
              qualified for foreign architectures, with an exact version
              restriction, separated by commas.

              The list includes all essential packages, packages listed in
              Build-Depends, Build-Depends-Arch, Build-Depends-Indep source
              control fields, any vendor specific builtin dependencies, and
              all their recursive dependencies.  On Debian and derivatives
              the dependency builtin is build-essential.

              For dependencies coming from the source control fields, all
              dependency alternatives and all providers of virtual packages
              depended on will be included.

              The list of environment variables that are known to affect the
              package build process, with each environment variable followed
              by an equal sign (‘=’) and the variable's quoted value, using
              double quotes (‘"’), and backslashes escaped (‘\\’).
