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 \(oq\fB#\fP\(cq). .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, using \fBdpkg\-source\fP is always better as it does not require any build dependencies to be installed 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 \-b Equivalent to \fB\-\-build=binary\fP or \fB\-\-build=any,all\fP. .TP .B \-B Equivalent to \fB\-\-build=any\fP. .TP .B \-A Equivalent to \fB\-\-build=all\fP. .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). .TP .B \-\-as\-root Only meaningful together with \fB\-\-target\fP (since dpkg 1.15.0).

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).

Otherwise, if none has been specified, \fBfakeroot\fP will be used by default, if the command is present. .I gain-root-command should start with the name of a program on the .B PATH and will get as arguments the name of the real command to run and the arguments it should take. .I gain-root-command can include parameters (they must be space-separated) but no shell metacharacters. .I gain-root-command might typically be .BR fakeroot ", " sudo ", " super " or " really . .B su is not suitable, since it can only invoke the user's shell with .B \-c instead of passing arguments individually to the command to be run. .TP .BR \-R ", " \-\-rules-file= \fIrules-file\fP Building a Debian package usually involves invoking .B debian/rules as a command with several standard parameters (since dpkg 1.14.17, long option since dpkg 1.18.8). With this option it's possible to use another program invocation to build the package (it can include space separated parameters). Alternatively it can be used to execute the standard rules file with another make program (for example by using .B /usr/local/bin/make \-f debian/rules as \fIrules-file\fR). .TP .BI \-\-check\-command= check-command Command used to check the \fB.changes\fP file itself and any artifact built referenced in the file (since dpkg 1.17.6). The command should take the \fB.changes\fP pathname as an argument. This command will usually be \fBlintian\fP. .TP .BI \-\-check\-option= opt Pass option \fIopt\fP to the \fIcheck-command\fP specified with \fBDEB_CHECK_COMMAND\fP or \fB\-\-check\-command\fP (since dpkg 1.17.6).
