distcc-pump - accelerate remote compilation with distcc
distcc-pump BUILD-COMMAND [ARGS] ...
eval ` distcc-pump --startup `; BUILD-COMMAND [ARGS] ... ; distcc-pump --shutdown
distcc-pump is part of distcc. It is used for distcc's pump mode. Distcc's pump mode
accelerates remote compilation with distcc by also distributing preprocessing to the
For a detailed description of pump mode, including most notably some important
restrictions, see the distcc(1) man page, in particular the HOW PUMP-MODE WORKS section
and the RESTRICTIONS ON PUMP MODE section.
The simplest usage is the form
distcc-pump COMMAND [ARG] ...
This will start an include server for distcc's "pump" mode; optionally run lsdistcc to
compute the distcc host list; set some auxiliary environment variables; change PATH to use
the distcc client in the same directory as the "distcc-pump" script; execute COMMAND with
the specified ARG(s) ; and then shut down the include server. The COMMAND is typically a
parallel build command, such as "make -j80", that will do many concurrent invocations of
An alternative way of invoking distcc-pump is to explicitly invoke "distcc-pump --startup"
to start the include server and "distcc-pump --shutdown" to stop the include server. The
"distcc-pump --startup" command will start up the include server, and will print out some
environment variable settings. These environment variables are used to communicate
between the pump-mode "distcc" client and the include server, and to communicate between
"distcc-pump --startup" and "distcc-pump --shutdown". The caller of "distcc-pump
--startup" is responsible for setting those environment variables before invoking "distcc"
or "distcc-pump --shutdown".
eval `distcc-pump --startup`
Note that distcc's pump-mode assumes that sources files will not be
modified during the lifetime of the include server, so modifying source files during a
build may cause inconsistent results.
When invoked in either the simple " distcc-pump COMMAND [ARG] ... " form, or as " distcc-
pump --startup ", the distcc-pump script will invoke lsdistcc whenever
DISTCC_POTENTIAL_HOSTS is set and DISTCC_HOSTS isn't. It will pass the value of
DISTCC_POTENTIAL_HOSTS to lsdistcc and use the output of lsdistcc to set DISTCC_HOSTS.
--help Displays summary instructions.
Starts an include server, and outputs the environment variable settings needed for
distcc(1) or distcc-pump --shutdown to access it.
Shuts down an include server started up by distcc-pump --startup.
The following environment variables are all optional.
The location of the distcc bin directory, which is normally inferred from the link-
resolved dirname of argv. If this location is in fact the bin directory inside
an installation (as will be the case when the pump script in the installation
executes), then Python executables and distcc itself will be retrieved from the
parent directory of the location.
The distcc servers that will be queried by lsdistcc in order to produce a value for
DISTCC_HOSTS. This value may be unset or null. In such cases, lsdistcc will not be
invoked, and distcc will use DISTCC_HOSTS or the distcc hosts configuration file,
as described in the "Host Specifications" section of distcc(1).
This variable is passed through to distcc but only if DISTCC_POTENTIAL_HOSTS is not
Extra arguments to pass to lsdistcc. See lsdistcc --help for more details.
Extra arguments to pass to the include server.
If set to "", then Python optimization is disabled.
