<title>DESCRIPTION</title>
<para>The <command>kdesrc-build</command> command is used in order to build
&kde; software directly from its source repositories. It can download from
Subversion or Git repositories, interfaces with the &kde; project database, and
supports controlling which options are passed to <command>make</command>(1) and
<command>cmake</command>(1). The operation of <command>kdesrc-build</command>
is driven by a configuration file, typically
<filename>~/.kdesrc-buildrc</filename>.</para>
<para>The <replaceable>module name</replaceable> or <replaceable>module set
name</replaceable> as given on the command line should be as those names were
defined in the configuration file (either in a <symbol>module</symbol>
definition or <option>use-modules</option> declaration, or in a
<option>module-set</option> definition). In addition, it can be the name of a
&kde; module listed in the &kde; project database (and you can precede the
module name with <symbol>+</symbol> to force this).</para>
<para><command>kdesrc-build</command> is designed to be able to be completely
headless (however, see <emphasis role="strong">ENVIRONMENT</emphasis>), and so
typically ignores its input completely. Command output is logged instead of
being shown on the kdesrc-build output.</para>
<para>Modules are built one after the other. If a module fails to update then
it is not built. <command>kdesrc-build</command> will not abort just because of
a module failure, instead it will keep trying to update and build subsequent
modules. By default, <command>kdesrc-build</command> will commence building a
module as soon as the source code update is complete for that module, even if
other updates are occurring concurrently.</para>
<para>At the end <command>kdesrc-build</command> will show which modules failed
to build, and where the logs were kept for that build run.</para> </refsect1>
<refsect1>
<title>OPTIONS</title>
<para><emphasis role="strong">NOTE</emphasis>: Some options have short forms,
but the <command>kdesrc-build</command> option parser does not support
combining short options into one at this point. (E.g. running
<option>kdesrc-build -pv</option> would not be the same as
<option>kdesrc-build --pretend --verbose</option>).</para>
<variablelist>
<varlistentry>
<term>
<option>-h, --help</option>
</term>
<listitem>
<para>

</para>
</listitem>
</varlistentry>
<varlistentry>
<term>
<option>-p, --pretend</option>
</term>
<listitem>
<para>
Operate in a "dry run" mode. No network accesses are made, no log files are
created, no modules are built, and no other permanent changes to disk are
made. One <emphasis>important exception</emphasis> is that if you try to
build a module that comes from the &kde; project database, and the
database hasn't been downloaded yet, the database will be downloaded
since the pretend-mode output may change significantly based on the
database results.
</para>

<listitem>
<para>
Skips the update and build phase and immediately attempts to uninstall the
modules given. <emphasis role="strong">NOTE</emphasis>: This is only
supported for buildsystems that supports the <command>make
uninstall</command> command (e.g. &kde; CMake-based).
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>
<option>--no-src</option>
</term>
<listitem>
<para>
Skips the source update phase. Other phases are included as normal.
<option>--no-svn</option> is a deprecated alias for this option and will be
removed in a future release.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>
<option>--no-metadata</option>
</term>
<listitem>
<para>
Skips the metadata update phase for KDE modules. Other phases (including
the source update phase) are included as normal. If you wish to avoid all network
updates you should also pass <option>--no-src</option>.
</para>
<para>
This option can be useful if you are frequently running
<command>kdesrc-build</command> since the metadata itself does not change
very often.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>
<option>--no-install</option>
</term>
<listitem>
<para>
Skips the install phase from the build. Other phases are included as
normal.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>
<option>--no-build</option>
</term>
<listitem>
<para>
Skips the build phase for the build. Internally the install phase depends
on the build phase completing so this is effectively equivalent to
<option>--src-only</option>, but the semantics may change in the future
(e.g. when test suites are moved into their own phase).
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>
<option>--no-tests</option>
</term>
<listitem>
<para>
Disables running the test suite for CMake-based modules. To be fully
effective this requires re-running CMake, which can be forced by using the
<option>--reconfigure</option> or <option>--refresh-build</option> options.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>
<option>--src-only</option>
</term>
<listitem>
<para>
Only performs the source update phase, does not build or install.
<option>--svn-only</option> is a deprecated alias for this option and will
be removed in a future release.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>
<option>--build-only</option>
</term>
<listitem>
<para>
Forces the build process to be performed without updating source code
first. In addition, installation is not performed. (Testing is still
performed if applicable, but this will change in a future release)
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>
<option>--metadata-only</option>
</term>
<listitem>
<para>
Only updates the build metadata needed for KDE modules, then exits. This is
useful to allow the <option>--pretend</option> option to work if you've never
run kdesrc-build. See also <option>--no-metadata</option>.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>
<option>--refresh-build</option>
</term>
<listitem>
<para>
Removes the build directory for a module before the build phase starts.
This has the desired side effect of forcing <command>kdesrc-build</command> to re-configure
the module and build it from a "pristine" state with no existing temporary
or intermediate output files. Use this option if you have problems getting
a module to build but realize it will take longer (possibly much longer)
for the build to complete as a result. When in doubt use this option for
the entire <command>kdesrc-build</command> run.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>
<option>--reconfigure</option>
</term>
<listitem>
<para>
Force CMake to be re-run, but without deleting the build directory.
Usually you actually want <option>--refresh-build</option>, but if you are
100% sure your change to <option>cmake-options</option> will not
invalidate your current intermediate output then this can save some time.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>
<option>--build-system-only</option>
</term>
<listitem>
<para>
Interrupts the build process for each module built: The build process
consists of normal setup up to and including running
<command>cmake</command> or <command>configure</command> (as appropriate),
but <command>make</command> is not run and no installation
is attempted. This is mostly only useful to get things like
<command>configure --help</command> and <command>cmake-gui</command> to
work. Normally you want <option>--reconfigure</option> or
<option>--refresh-build</option>.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>
<option>--resume-from=<replaceable>foo</replaceable></option>
</term>
<listitem>
<para>
Use this option to skip module processing until the module
<replaceable>foo</replaceable> is encountered.
<replaceable>foo</replaceable> and all subsequent modules will be processed
normally as if they had been specified on the command line. If you use this
option because of a build failure you may want to consider using
<option>--no-src</option> in addition to skip the resultant source update
phase.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>
<option>--resume-after=<replaceable>foo</replaceable></option>
</term>
<listitem>
<para>
This is just like <option>--resume-from</option>, except that the module
<replaceable>foo</replaceable> is <emphasis>not</emphasis> included in the
list of modules to consider. You might use this if you've manually
built/installed foo after fixing the build and just want to resume from
there.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>
<option>--resume</option>
</term>
<listitem>
<para>
This option can be used to run <command>kdesrc-build</command> after it has
had a build failure.
</para>
<para>
It resumes the build from the module that failed, using the list of modules
that were waiting to be built before, and disables source and metadata
updates as well. The use case is when a simple mistake or missing
dependency causes the build failure. Once you correct the error you can
quickly get back into building the modules you were building before,
without fiddling with <option>--resume-from</option> and
<option>--stop-before</option>.
</para>
<para>
This is even handier with the <option>--stop-on-failure</option> option,
especially if you're initially setting up your development environment.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>
<option>--stop-before=<replaceable>foo</replaceable></option>
</term>
<listitem>
<para>
This is similar to the <option>--resume-from</option> flag. This option
causes the module list for the given build to be truncated just
<emphasis>before</emphasis> <replaceable>foo</replaceable> would normally
have been built. <replaceable>foo</replaceable> is <emphasis>not</emphasis>
built (but see <option>--stop-after</option>).
</para>
<para>
This flag may be used with <option>--resume-from</option> or
<option>--resume-after</option>.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>
<option>--stop-after=<replaceable>foo</replaceable></option>
</term>
<listitem>
<para>
This is just like <option>--stop-before</option>, except that the given module
<emphasis>is</emphasis> included in the build.
</para>
<para>
This flag may be used with <option>--resume-from</option> or
<option>--resume-after</option>.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>
<option>--include-dependencies</option>
</term>
<listitem>
<para>
This causes <command>kdesrc-build</command> to include not only the modules
it would normally build (either because they were specified on the command
line, or mentioned in the configuration file), but also to include
<emphasis>known dependencies</emphasis> of those modules in the build.
</para>
<para>
Dependencies are <quote>known</quote> to <command>kdesrc-build</command> based on the
contents of the special <emphasis>kde-build-metadata</emphasis> git
repository, which is managed for you by the script (see also the
<option>--metadata-only</option> option). The KDE community keeps the
dependency information in that module up to date, so if
<command>kdesrc-build</command> appears to show the wrong dependencies then
it may be due to missing or incorrect dependency information.
</para>
<para>
All known dependencies will be included, which may be more than you need.
Consider using the <option>--resume-from</option> option (and similar
options) to control the build list when using this option.
</para>
<para>
To see just the list of modules that would be built, use <option>--print-modules</option> or
<option>--pretend</option>.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>
<option>--rebuild-failures</option>
</term>
<listitem>
<para>
Use this option to build only those modules which failed to build on a
previous <command>kdesrc-build</command> run. This is useful if a
significant number of failures occurred mixed with successful builds. After
fixing the issue causing the build failures you can then easily build only
the modules that failed previously.</para>
<para>Note that the list of <quote>previously-failed modules</quote> is
reset every time a <command>kdesrc-build</command> run finishes with some
module failures. However it is not reset by a completely successful build,
so you can successfully rebuild a module or two and this flag will still
work.</para>
<para>This option was added for kdesrc-build 15.09.</para>
</listitem>
</varlistentry>
<varlistentry>
<term>
<option>--stop-on-failure</option>
</term>
<listitem>
<para>
This option causes the build to abort as soon as a failure occurs. Useful when you're setting
up your initial development environment. Without this flag, <command>kdesrc-build</command>
will try to press on with the rest of the modules in the build to avoid wasting time in case
the problem is with a single module.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>
<option>--ignore-modules</option>
</term>
<listitem>
<para>
Forces <emphasis role="strong">ALL</emphasis> modules that follow this
option to be excluded from consideration by
<command>kdesrc-build</command>. This might be useful if you know you want
to process all modules except for specific exceptions.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>
<option>--rc-file=<replaceable>foo</replaceable></option>
</term>
<listitem>
<para>
Use the given file, <replaceable>foo</replaceable>, for the configuration
instead of <filename>~/.kdesrc-buildrc</filename> or
<filename>./kdesrc-buildrc</filename>. The file can be empty, but must
exist.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>
<option>--prefix=<replaceable>foo</replaceable></option>
</term>
<listitem>
<para>
Overrides the <option>kdedir</option> setting to be
<replaceable>foo</replaceable> for this run. In addition, implies
<option>--reconfigure</option>. It <emphasis>does not</emphasis> actually
perform the action you would think it does (overriding the
<option>prefix</option> option to change where modules are installed),
although by default modules are installed to the <option>kdedir</option>
setting if <option>prefix</option> is not set.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>
<option>--nice=<replaceable>foo</replaceable></option>
</term>
<listitem>
<para>
Changes the CPU priority given to <command>kdesrc-build</command> (and all
processes used by <command>kdesrc-build</command> e.g.
<command>make</command>(1)). <replaceable>foo</replaceable> should be an
integer number between -20 and 19. Positive values are "nicer" to the rest
of the system (i.e. lower priority).
</para>
<para>
Note that the possible priorities available on your system may be different
than listed here, see <command>nice</command>(2) for more information. Note
also that this only changes <emphasis>CPU</emphasis> priority, often you
want to change <emphasis>I/O</emphasis> priority on systems where that is
supported. There is no command-line option for I/O priority adjustment, but
there is a configuration file option: <option>use-idle-io-priority</option>
(although like all options, there is a generic way to set this from the
command line).
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>
<option>--run=<replaceable>foo</replaceable></option>
</term>
<listitem>
<para>
Runs the program named by <replaceable>foo</replaceable> using
<command>kdesrc-build</command>'s normal build environment. All command
line arguments present after this option are passed to
<replaceable>foo</replaceable> as it is run.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>
<option>--query=<replaceable>mode</replaceable></option>
</term>
<listitem>
<para>
This command causes <command>kdesrc-build</command> to query a parameter of the
modules in the build list (either passed on the command line or read in from
the configuration file), outputting the result to screen (one module per line).
</para>
<para>
This option must be provided with a <quote>query mode</quote>, which should be
one of the following:</para>
<itemizedlist>
<listitem><para><option>source-dir</option>, which causes
<command>kdesrc-build</command> to output the full path to where the
module's source code is stored.
</para></listitem>
<listitem><para><option>build-dir</option>, which causes
<command>kdesrc-build</command> to output the full path to where the
module build process occurs.
</para></listitem>
<listitem><para><option>install-dir</option>, which causes
<command>kdesrc-build</command> to output the full path to where the
module will be installed.
</para></listitem>
<listitem><para><option>project-path</option>, which causes
<command>kdesrc-build</command> to output the location of the module
within the hierarchy of KDE source code repositories.
</para></listitem>
<listitem><para><option>branch</option>, which causes
<command>kdesrc-build</command> to output the resolved git branch that
will be used for each module, based on the <option>tag</option>,
<option>branch</option> and <option>branch-group</option> settings in
effect.
</para></listitem>
<listitem><para>Otherwise, option names that are valid for modules in the
configuration file can be used, the resolved value of which will be
listed for each module.
</para></listitem>
</itemizedlist>
<para>
If a single module is passed on the command line, then the output is simply the
value of the parameter being queried. If multiple (or no) modules are passed on
the command line, then each line is prefixed by the name of the module. Either
way, <command>kdesrc-build</command> stops running once each value is output.
</para>
<para>This option was added with <command>kdesrc-build</command> 16.05.</para>
<informalexample>
<para>For example, the command <quote><command>kdesrc-build</command>
<parameter>--query</parameter>
<parameter><replaceable>branch</replaceable></parameter>
<parameter><replaceable>kactivities</replaceable></parameter>
<parameter><replaceable>kdepim</replaceable></parameter></quote>
might end up with output like:</para>
<screen>
kactivities: master
kdepim: master
</screen>
</informalexample>
</listitem>
</varlistentry>
<varlistentry>
<term>
<option>--print-modules</option>
</term>
<listitem>
<para>
Takes all actions up to and including dependency reordering of the modules
specified on the command line (or configuration file), prints the modules
that would be processed one per line, and then exits without further action.
</para>
<para>
The <literal>kde-project</literal> metadata is downloaded first (though, see
<option>--pretend</option> or <option>--no-src</option>).
</para>
<para>
The output is not fully compatible with usage by scripts as other output messages
may be generated until the module list is shown.
</para>
<para>
This is mostly just useful for quickly determining what
<command>kdesrc-build</command> understands a module's dependencies to be,
which means it's only useful for <literal>kde-projects</literal> modules.
This option is also compatible with <option>--resume-from</option>,
<option>--resume-after</option>, <option>--stop-before</option>, and
<option>--stop-after</option>.

<listitem>
<para>
This will fill your terminal with descriptions and debugging output,

</para>
</listitem>
</varlistentry>
<varlistentry>
<term>
<option>--force-build</option>
</term>
<listitem>
<para>
Normally when <command>kdesrc-build</command> notices that there is no
source update on a module which was previously successfully installed, it
does not attempt to build or install that module. You can pass this flag to
disable that behavior and always run <command>make</command>.

<varlistentry>
<term>
<option>--no-snapshots</option>
</term>
<listitem>
<para>
Normally <command>kdesrc-build</command> supports using source repository
tarball snapshots to reduce load on &kde; infrastructure for git clones for
some &kde; modules. Passing this option disables this feature.

<term>
<option>--delete-my-patches</option>
</term>
<listitem>
<para>
This option must be passed to allow <command>kdesrc-build</command> to
remove conflicting source directories. Currently even this only happens
when trying to clone a git-based module if an existing source directory is
present. Never specify this option unless it is suggested by
<command>kdesrc-build</command>, and only if you don't mind the source
directories that are referenced being deleted and re-cloned.

<envar>PATH</envar>
</term>
<listitem>
<para>
This environment variable controls the default search path for executables.
You can use the <option>binpath</option> configuration file option to add
to this variable (e.g. for running from <command>cron</command>(8)).

<envar>LC_</envar>*
</term>
<listitem>
<para>
Environment variables starting with LC_ control the locale used by
<command>kdesrc-build</command>. Although <command>kdesrc-build</command>
is still not localizable at this point, many of the commands it uses are.
<command>kdesrc-build</command> normally sets <envar>LC_ALL</envar>=C for
commands that its must examine the output of but you can manually do this
as well. If setting <envar>LC_ALL</envar>=C fixes a
<command>kdesrc-build</command> problem please submit a bug report.

<term>
<envar>SSH_AGENT_PID</envar>
</term>
<listitem>
<para>
This environment variable is checked to see if
<command>ssh-agent</command>(1) is running, but only if
<command>kdesrc-build</command> determines that you are checking out a
module that requires an SSH login (but you should know this as no module
requires this by default).
</para>

<term>
<envar>KDESRC_BUILD_USE_TTY</envar>
</term>
<listitem>
<para>
If set, this variable forces <command>kdesrc-build</command> not to close
its input while executing system processes. Normally
<command>kdesrc-build</command> closes <symbol>stdin</symbol> since the
<symbol>stdout</symbol> and <symbol>stderr</symbol> for its child processes
are redirected and therefore the user would never see an input prompt
anyways.
</para>

<term>
<envar>KDESRC_BUILD_DUMP_CONTEXT</envar>
</term>
<listitem>
<para>
If set, this variable prints out a description of its "build context" just
after reading options and command line arguments and determining which
modules to build. You pretty much never want to set this.

<para>
Many programs are used by <command>kdesrc-build</command> in the course of
its execution, including <command>svn</command>(1),
<command>git</command>(1), <command>make</command>(1), and
<command>cmake</command>(1). Each of these programs may have their own
response to environment variables being set.
<command>kdesrc-build</command> will pass environment variables that are
set when it is run onto these processes. You can ensure certain environment
variables (e.g. <envar>CC</envar> or <envar>CXX</envar>) are set by using
the <option>set-env</option> configuration file option.

<term>
$ <userinput><command>kdesrc-build</command></userinput>

<listitem>
<para>
Downloads, builds and installs all modules listed in the configuration
file, in the order defined therein.

<term>
$ <userinput><command>kdesrc-build</command> <option>--pretend</option></userinput>
</term>
<listitem>
<para>
Same as above, except no permanent actions are taken (specifically no log
files are created, downloads performed, build processes run, etc.).
<emphasis role="strong">EXCEPTION</emphasis>: If you are trying to build a
module defined in the &kde; project database, and the database has not been
downloaded yet, <command>kdesrc-build</command> will download the database
since this can significantly affect the final build order.

Deletes the build directory for the <emphasis>kdebase</emphasis> module set

without updating the source code in-between.

<listitem>
<para>
Forces <command>kdesrc-build</command> to read an empty configuration file
and simulate the resultant build process. This shows what would happen by
default with no configuration file, without an error message about a
missing configuration file.

<term>
$ <userinput><command>kdesrc-build</command> <symbol>+kdebase/kde-baseapps</symbol></userinput>
</term>
<listitem>
<para>
Downloads, builds and installs the <symbol>kde-baseapps</symbol> module
from the &kde; project database. Since the module name is preceded by a
<symbol>+</symbol> it is assumed to defined in the &kde; project
database even if this hasn't been specifically configured in the
configuration file.
</para>
<para>
The <symbol>kdebase/</symbol> portion forces
<command>kdesrc-build</command> to ignore any <symbol>kde-baseapps</symbol>
modules that are not children of the <symbol>kdebase</symbol> supermodule
in the project database (although it is contrived for this example).

<para>
Downloads, builds and installs all modules defined in the configuration
file but overrides the <symbol>cmake-options</symbol> option to have
