kdesrc-build - Online in the Cloud

PROGRAM:

NAME

kdesrc-build - Downloads, builds and installs KDE software.

SYNOPSIS

kdesrc-build [OPTIONS...] [Module name | Module set name...]

DESCRIPTION

The kdesrc-build 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 make(1) and
cmake(1). The operation of kdesrc-build is driven by a configuration file, typically
~/.kdesrc-buildrc.

The module name or module set name as given on the command line should be as those names
were defined in the configuration file (either in a module definition or use-modules
declaration, or in a module-set 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 + to
force this).

kdesrc-build is designed to be able to be completely headless (however, see ENVIRONMENT),
and so typically ignores its input completely. Command output is logged instead of being
shown on the kdesrc-build output.

Modules are built one after the other. If a module fails to update then it is not built.
kdesrc-build will not abort just because of a module failure, instead it will keep trying
to update and build subsequent modules. By default, kdesrc-build will commence building a
module as soon as the source code update is complete for that module, even if other
updates are occurring concurrently.

At the end kdesrc-build will show which modules failed to build, and where the logs were
kept for that build run.

OPTIONS

NOTE: Some options have short forms, but the kdesrc-build option parser does not support
combining short options into one at this point. (E.g. running kdesrc-build -pv would not
be the same as kdesrc-build --pretend --verbose).

-h, --help
Shows a brief synopsis and frequently-used command line options.

-p, --pretend
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 important
exception 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.

--install
Skips the update and build phase and immediately attempts to install the modules
given.

--uninstall
Skips the update and build phase and immediately attempts to uninstall the modules
given. NOTE: This is only supported for buildsystems that supports the make uninstall
command (e.g. KDE CMake-based).

--no-src
Skips the source update phase. Other phases are included as normal. --no-svn is a
deprecated alias for this option and will be removed in a future release.

--no-install
Skips the install phase from the build. Other phases are included as normal.

--no-build
Skips the build phase for the build. Internally the install phase depends on the build
phase completing so this is effectively equivalent to --src-only, but the semantics
may change in the future (e.g. when test suites are moved into their own phase).

--no-tests
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 --reconfigure or
--refresh-build options.

--src-only
Only performs the source update phase, does not build or install. --svn-only is a
deprecated alias for this option and will be removed in a future release.

--build-only
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)

--refresh-build
Removes the build directory for a module before the build phase starts. This has the
desired side effect of forcing kdesrc-build 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 kdesrc-build run.

--reconfigure
Force CMake to be re-run, but without deleting the build directory. Usually you
actually want --refresh-build, but if you are 100% sure your change to cmake-options
will not invalidate your current intermediate output then this can save some time.

--build-system-only
Interrupts the build process for each module built: The build process consists of
normal setup up to and including running cmake or configure (as appropriate), but make
is not run and no installation is attempted. This is mostly only useful to get things
like configure --help and cmake-gui to work. Normally you want --reconfigure or
--refresh-build.

--resume-from=foo
Use this option to skip module processing until the module foo is encountered. foo
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 --no-src in addition to skip the resultant source update phase.

--resume-after=foo
This is just like --resume-from, except that the module foo is not 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.

--ignore-modules
Forces ALL modules that follow this option to be excluded from consideration by
kdesrc-build. This might be useful if you know you want to process all modules except
for specific exceptions.

--rc-file=foo
Use the given file, foo, for the configuration instead of ~/.kdesrc-buildrc or
./kdesrc-buildrc. The file can be empty, but must exist.

--prefix=foo
Overrides the kdedir setting to be foo for this run. In addition, implies
--reconfigure. It does not actually perform the action you would think it does
(overriding the prefix option to change where modules are installed), although by
default modules are installed to the kdedir setting if prefix is not set.

--nice=foo
Changes the CPU priority given to kdesrc-build (and all processes used by kdesrc-build
e.g. make(1)). foo should be an integer number between -20 and 19. Positive values
are "nicer" to the rest of the system (i.e. lower priority).

Note that the possible priorities available on your system may be different than
listed here, see nice(2) for more information. Note also that this only changes CPU
priority, often you want to change I/O 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: use-idle-io-priority (although like all options, there is a
generic way to set this from the command line).

--run=foo
Runs the program named by foo using kdesrc-build's normal build environment. All
command line arguments present after this option are passed to foo as it is run.

--color
Enables "colorful output". (Enabled by default).

--no-color
Disables "colorful output". This can be made permanent by setting the colorful-output
option to false (or 0) in your configuration file.

--async
Have kdesrc-build start the build process for a module as soon as the source code has
finished downloading. Without this option kdesrc-build performs all source updates at
once and only then starts with the build process. This option is enabled by default.

--no-async
Disables asynchronous building of modules. See --async for a more detailed
description. Note that kdesrc-build's output will be slightly different in this mode.

-v, --verbose
Increases the level of verbosity of kdesrc-build output (which is already fairly
verbose!)

-q, --quiet
Makes kdesrc-build less noisy. Only important messages are shown.

--really-quiet
Makes kdesrc-build even less noisy. Only warnings/errors are shown.

--debug
This will fill your terminal with descriptions and debugging output, usually
unintelligible, describing what kdesrc-build is doing (and thinks it should be doing).
The flag is included since the output may sometimes prove useful for debugging.

--force-build
Normally when kdesrc-build 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 make.

--no-snapshots
Normally kdesrc-build 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.

--delete-my-patches
This option must be passed to allow kdesrc-build 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 kdesrc-build, and only if you don't mind the source directories that are
referenced being deleted and re-cloned.

--foo=bar
Any option not listed above is checked to see if it matches the list of possible
configuration file options. If so, the configuration file option foo is temporarily
set to bar for the duration of this run.

--module,foo=bar
Like above, but option foo is only set to bar for the module module. This does not
work for module sets yet, you must repeat this for each module you want to be
affected. (Of course, you could simply edit your configuration file...)

EXIT STATUS

0
Success

1
Normally this means some part of the update, build or install process failed, but is
also used for any abnormal program end not otherwise covered below.

5
A signal was received that killed kdesrc-build, but it attempted to perform normal
closedown.

8
Unknown option was passed on the command line.

99
An exception was raised that forced kdesrc-build to abort early.

ENVIRONMENT

HOME
Used for tilde-expansion of file names, and is the default base for the source, build,
and installation directories.

PATH
This environment variable controls the default search path for executables. You can
use the binpath configuration file option to add to this variable (e.g. for running
from cron(8)).

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

SSH_AGENT_PID
This environment variable is checked to see if ssh-agent(1) is running, but only if
kdesrc-build 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).

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

KDESRC_BUILD_DUMP_CONTEXT
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.

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