deb-buildinfo(5)                dpkg suite               deb-buildinfo(5)

NAME         top

       deb-buildinfo - Debian build information file format

SYNOPSIS         top

       filename.buildinfo

DESCRIPTION         top

       Each Debian source package build can record the build information
       in a .buildinfo control file, which contains a number of fields in
       deb822(5) format.

       Each field begins with a tag, such as Source or Binary (case
       insensitive), followed by a colon, and the body of the field (case
       sensitive unless stated otherwise).  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 RFC9580.

       The name of the .buildinfo file will depend on the type of build
       and will be as specific as necessary but not more; the name will
       be:

       source-name_binary-version_arch.buildinfo
           for a build that includes any

       source-name_binary-version_all.buildinfo
           otherwise for a build that includes all

       source-name_source-version_source.buildinfo
           otherwise for a build that includes 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 in context)
           This folded field is a space-separated list of binary packages
           built.  If the build is source-only, then the field is omitted
           (since dpkg 1.20.0).

       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).

       Binary-Only-Changes:
        changelog-entry
           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, weak)
       Checksums-Sha1: (required, weak)
       Checksums-Sha256: (required, strong)
        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
           Checksums-Sha256.

           Note: The MD5 and SHA-1 checksums are considered weak, and
           should never be assumed to be sufficient for secure
           verification.

           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
           name.

           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,
           etc.

       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 allowed 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.

       Build-Tainted-By:
        taint-reason-list
           This folded field contains a space-separated list of
           non-exhaustive reason tags (formed by alphanumeric and dash
           characters) which identify why the current build has been
           tainted (since dpkg 1.19.5).

           On Debian and derivatives the following reason tags can be
           emitted:

           usr-local-has-configs
               The system has configuration files under /usr/local/etc.

           usr-local-has-includes
               The system has header files under /usr/local/include.

           usr-local-has-programs
               The system has programs under /usr/local/bin or
               /usr/local/sbin.

           usr-local-has-libraries
               The system has libraries, either static or shared under
               /usr/local/lib.

           can-execute-cross-built-programs
               The system can execute cross built programs, either
               directly or via some emulation layer.

               Since dpkg 1.21.10.

       Installed-Build-Depends: (required)
        package-list
           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.

       Environment:
        variable-list
           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 (‘\\’).
