+.SH NAME
+dpkg\-buildpackage \- build binary or source packages from sources
+.
+.SH SYNOPSIS
+.B dpkg\-buildpackage
+.RI [ option ...]
+.
+.SH DESCRIPTION
+.B dpkg\-buildpackage
+is a program that automates the process of building a Debian package. It
+consists of the following steps:
+.IP \fB1.\fP 3
+It prepares the build environment by setting various environment
+variables (see \fBENVIRONMENT\fP), runs the \fBinit\fP hook, and calls
+\fBdpkg\-source \-\-before\-build\fP (unless \fB\-T\fP or \fB\-\-target\fP
+has been used).
+.IP \fB2.\fP 3
+It checks that the build-dependencies and build-conflicts
+are satisfied (unless \fB\-d\fP or \fB\-\-no\-check\-builddeps\fP is specified).
+.IP \fB3.\fP 3
+If one or more specific targets have been selected with the \fB\-T\fP or
+\fB\-\-target\fP option, it calls those targets and stops here. Otherwise it
+runs the \fBpreclean\fP hook and calls \fBfakeroot debian/rules clean\fP to
+clean the build-tree (unless \fB\-nc\fP or \fB\-\-no\-pre\-clean\fP
+is specified).
+.IP \fB4.\fP 3
+It runs the \fBsource\fP hook and calls \fBdpkg\-source \-b\fP to generate
+the source package (if a \fBsource\fP build has been requested with
+\fB\-\-build\fP or equivalent options).
+.IP \fB5.\fP 3
+It runs the \fBbuild\fP hook and calls \fBdebian/rules\fP \fIbuild-target\fP,
+then runs the \fBbinary\fP hook followed by \fBfakeroot debian/rules\fP
+\fIbinary-target\fP (unless a source-only build has been requested with
+\fB\-\-build=source\fP or equivalent options).
+Note that \fIbuild-target\fR and \fIbinary-target\fP are either \fBbuild\fP
+and \fBbinary\fP (default case, or if an \fBany\fP and \fBall\fP build
+has been requested with \fB\-\-build\fP or equivalent options), or
+\fBbuild\-arch\fP and \fBbinary\-arch\fP (if an \fBany\fP and not \fBall\fP
+build has been requested with \fB\-\-build\fP or equivalent options), or
+\fBbuild\-indep\fP and \fBbinary\-indep\fP (if an \fBall\fP and not \fBany\fP
+build has been requested with \fB\-\-build\fP or equivalent options).
+.IP \fB6.\fP 3
+It runs the \fBbuildinfo\fP
+hook and calls \fBdpkg\-genbuildinfo\fP to generate a \fB.buildinfo\fP file.
+Several \fBdpkg\-buildpackage\fP options are forwarded to
+\fBdpkg\-genbuildinfo\fP.
+.IP \fB7.\fP 3
+It runs the \fBchanges\fP hook and calls \fBdpkg\-genchanges\fP to
+generate a \fB.changes\fP file.
+The name of the \fB.changes\fP file will depend on the type of build and
+will be as specific as necessary but not more;
+for a build that includes \fBany\fP the name will be
+\fIsource-name\fP\fB_\fP\fIbinary-version\fP\fB_\fP\fIarch\fP\fB.changes\fP,
+or otherwise for a build that includes \fBall\fP the name will be
+\fIsource-name\fP\fB_\fP\fIbinary-version\fP\fB_\fP\fBall.changes\fP,
+or otherwise for a build that includes \fBsource\fP the name will be
+\fIsource-name\fP\fB_\fP\fIsource-version\fP\fB_\fP\fBsource.changes\fP.
+Many \fBdpkg\-buildpackage\fP options are forwarded to
+\fBdpkg\-genchanges\fP.
+.IP \fB8.\fP 3
+It runs the \fBpostclean\fP hook and if \fB\-tc\fP or \fB\-\-post\-clean\fP
+is specified, it will call \fBfakeroot debian/rules clean\fP again.
+.IP \fB9.\fP 3
+It calls \fBdpkg\-source \-\-after\-build\fP.
+.IP \fB10.\fP 3
+It runs the \fBcheck\fP hook and calls a package checker for the
+\fB.changes\fP file (if a command is specified in \fBDEB_CHECK_COMMAND\fP or
+with \fB\-\-check\-command\fP).
+.IP \fB11.\fP 3
+It runs the \fBsign\fP hook and calls \fBgpg2\fP or \fBgpg\fP (as long as it
+is not an UNRELEASED build, or \fB\-\-no\-sign\fP is specified) to sign the
+\fB.dsc\fP file (if any, unless
+\fB\-us\fP or \fB\-\-unsigned\-source\fP is specified), the \fB.buildinfo\fP
+file (unless \fB\-ui\fP, \fB\-\-unsigned\-buildinfo\fP,
+\fB\-uc\fP or \fB\-\-unsigned\-changes\fP is specified) and
+the \fB.changes\fP file (unless \fB\-uc\fP or \fB\-\-unsigned\-changes\fP
+is specified).
+.IP \fB12.\fP 3
+It runs the \fBdone\fP hook.
+.
+.SH OPTIONS
+All long options can be specified both on the command line and in the
+\fBdpkg\-buildpackage\fP system and user configuration files.
+Each line in the configuration file is either an option (exactly the same
+as the command line option but without leading hyphens) or a comment (if
+it starts with a ‘\fB#\fP’).
+
+.TP
+.BI \-\-build= type
+Specifies the build \fItype\fP from a comma-separated list of components
+(since dpkg 1.18.5).
+Passed to \fBdpkg\-genchanges\fP.
+
+The allowed values are:
+.RS
+.TP
+.B source
+Builds the source package.
+Note: when using this value standalone and if what you want is simply to
+(re-)build the source package from a clean source tree, using
+\fBdpkg\-source\fP directly is always a better option as it does not
+require any build dependencies to be installed which are otherwise
+needed to be able to call the \fBclean\fP target.
+.TP
+.B any
+Builds the architecture specific binary packages.
+.TP
+.B all
+Builds the architecture independent binary packages.
+.TP
+.B binary
+Builds the architecture specific and independent binary packages.
+This is an alias for \fBany,all\fP.
+.TP
+.B full
+Builds everything.
+This is an alias for \fBsource,any,all\fP, and the same as the default
+case when no build option is specified.
+.RE
+.TP
+.B \-g
+Equivalent to \fB\-\-build=source,all\fP (since dpkg 1.17.11).
+.TP
+.B \-G
+Equivalent to \fB\-\-build=source,any\fP (since dpkg 1.17.11).

+.TP
+.B \-S
+Equivalent to \fB\-\-build=source\fP.
+.TP
+.B \-F
+Equivalent to \fB\-\-build=full\fP, \fB\-\-build=source,binary\fP or
+\fB\-\-build=source,any,all\fP (since dpkg 1.15.8).
+.TP
+.BR \-\-target= \fItarget\fP[,...]
+.TQ
+.BR "\-\-target " \fItarget\fP[,...]
+.TQ
+.BR \-T ", " \-\-rules\-target= \fItarget\fP[,...]
+Calls \fBdebian/rules\fP \fItarget\fP once per target specified, after
+having setup the build environment (except for calling
+\fBdpkg\-source \-\-before\-build\fP), and stops the package build process
+here (since dpkg 1.15.0, long option since dpkg 1.18.8, multi-target
+support since dpkg 1.18.16).
+If \fB\-\-as\-root\fP is also given, then the command is executed
+as root (see \fB\-\-root\-command\fP).
+Note that known targets that are required to
+be run as root do not need this option (i.e. the \fBclean\fP, \fBbinary\fP,
+\fBbinary\-arch\fP and \fBbinary\-indep\fP targets).

+for the host machine.
+.TP
+.BR \-t ", " \-\-host\-type " \fIgnu-system-type\fP"

+of the host Debian architecture.
+.TP

+Specify the profile(s) we build, as a comma-separated list (since dpkg 1.17.2,
+long option since dpkg 1.18.8).
+The default
+behavior is to build for no specific profile. Also sets them (as a space
+separated list) as the \fBDEB_BUILD_PROFILES\fP environment variable which
+allows, for example, \fBdebian/rules\fP files to use this information for
+conditional builds.
+.TP
+.BR \-j ", " \-\-jobs [=\fIjobs\fP|\fBauto\fP]
+Number of jobs allowed to be run simultaneously, number of jobs matching
+the number of online processors if \fBauto\fP is specified
+(since dpkg 1.17.10), or unlimited number if \fIjobs\fP is not specified,
+equivalent to the
+.BR make (1)
+option of the same name (since dpkg 1.14.7, long option since dpkg 1.18.8).
+Will add itself to the \fBMAKEFLAGS\fP
+environment variable, which should cause all subsequent make
+invocations to inherit the option, thus forcing the parallel setting on
+the packaging (and possibly the upstream build system if that uses make)
+regardless of their support for parallel builds, which might cause build
+failures.
+Also adds \fBparallel=\fP\fIjobs\fP or
+\fBparallel\fP to the \fBDEB_BUILD_OPTIONS\fP environment variable which
+allows debian/rules files to use this information for their own purposes.
+The \fB\-j\fP value will override the \fBparallel=\fP\fIjobs\fP or
+\fBparallel\fP option in the \fBDEB_BUILD_OPTIONS\fP environment variable.
+Note that the \fBauto\fP value will get replaced by the actual number of
+currently active processors, and as such will not get propagated to any
+child process. If the number of online processors cannot be inferred then
+the code will fallback to using serial execution (since dpkg 1.18.15),
+although this should only happen on exotic and unsupported systems.
+.TP
+.BR \-J ", " \-\-jobs\-try [=\fIjobs\fP|\fBauto\fP]
+This option (since dpkg 1.18.2, long option since dpkg 1.18.8) is equivalent
+to the \fB\-j\fP option except that it does not set the \fBMAKEFLAGS\fP
+environment variable, and as such it is safer to use with any package
+including those that are not parallel-build safe.
+
+\fBauto\fP is the default behavior (since dpkg 1.18.11). Setting the number
+of jobs to 1 will restore a serial behavior.

+.SH NOTES
+.SS Compiler flags are no longer exported
+Between dpkg 1.14.17 and 1.16.1, \fBdpkg\-buildpackage\fP
+exported compiler flags (\fBCFLAGS\fP, \fBCXXFLAGS\fP, \fBFFLAGS\fP,
+\fBCPPFLAGS\fP and \fBLDFLAGS\fP) with values as returned
+by \fBdpkg\-buildflags\fP. This is no longer the case.
+.SS Default build targets
+\fBdpkg\-buildpackage\fP is using the \fBbuild\-arch\fP and
+\fBbuild\-indep\fP targets since dpkg 1.16.2. Those targets are thus
+mandatory. But to avoid breakages of existing packages, and ease
+the transition, if the source package does not build both architecture
+independent and dependent binary packages (since dpkg 1.18.8) it will
+fallback to use the \fBbuild\fP target if \fBmake \-f debian/rules \-qn\fP
+\fIbuild-target\fP returns 2 as exit code.
+.SH BUGS
+It should be possible to specify spaces and shell metacharacters
+and initial arguments for
