bitbake options

Basic options

Build performance tuning for OE/Yocto

• bitbake -h

bitbake -h Usage: bitbake [options] [recipename/target ...]

   Executes the specified task (default is 'build') for a given set of target recipes (.bb files).
   It is assumed there is a conf/bblayers.conf available in cwd or in BBPATH which
   will provide the layer, BBFILES and other configuration information.

Options:

 --version             show program's version number and exit
 -h, --help            show this help message and exit
 -b BUILDFILE, --buildfile=BUILDFILE
                       Execute tasks from a specific .bb recipe directly.
                       WARNING: Does not handle any dependencies from other
                       recipes.
 -k, --continue        Continue as much as possible after an error. While the
                       target that failed and anything depending on it cannot
                       be built, as much as possible will be built before
                       stopping.
 -a, --tryaltconfigs   Continue with builds by trying to use alternative
                       providers where possible.
 -f, --force           Force the specified targets/task to run (invalidating
                       any existing stamp file).
 -c CMD, --cmd=CMD     Specify the task to execute. The exact options
                       available depend on the metadata. Some examples might
                       be 'compile' or 'populate_sysroot' or 'listtasks' may
                       give a list of the tasks available.
 -C INVALIDATE_STAMP, --clear-stamp=INVALIDATE_STAMP
                       Invalidate the stamp for the specified task such as
                       'compile' and then run the default task for the
                       specified target(s).
 -r PREFILE, --read=PREFILE
                       Read the specified file before bitbake.conf.
 -R POSTFILE, --postread=POSTFILE
                       Read the specified file after bitbake.conf.
 -v, --verbose         Output more log message data to the terminal.
 -D, --debug           Increase the debug level. You can specify this more
                       than once.
 -n, --dry-run         Don't execute, just go through the motions.
 -S DUMP_SIGNATURES, --dump-signatures=DUMP_SIGNATURES
                       Dump out the signature construction information, with
                       no task execution. Parameters are passed to the
                       signature handling code, use 'none' if no specific
                       handler is required.
 -p, --parse-only      Quit after parsing the BB recipes.
 -s, --show-versions   Show current and preferred versions of all recipes.
 -e, --environment     Show the global or per-package environment complete
                       with information about where variables were
                       set/changed.
 -g, --graphviz        Save dependency tree information for the specified
                       targets in the dot syntax.
 -I EXTRA_ASSUME_PROVIDED, --ignore-deps=EXTRA_ASSUME_PROVIDED
                       Assume these dependencies don't exist and are already
                       provided (equivalent to ASSUME_PROVIDED). Useful to
                       make dependency graphs more appealing
 -l DEBUG_DOMAINS, --log-domains=DEBUG_DOMAINS
                       Show debug logging for the specified logging domains
 -P, --profile         Profile the command and save reports.
 -u UI, --ui=UI        The user interface to use (e.g. knotty, hob, depexp).
 -t SERVERTYPE, --servertype=SERVERTYPE
                       Choose which server to use, process or xmlrpc.
 --revisions-changed   Set the exit code depending on whether upstream
                       floating revisions have changed or not.
 --server-only         Run bitbake without a UI, only starting a server
                       (cooker) process.
 -B BIND, --bind=BIND  The name/address for the bitbake server to bind to.
 --no-setscene         Do not run any setscene tasks. sstate will be ignored
                       and everything needed, built.
 --remote-server=REMOTE_SERVER
                       Connect to the specified server.
 -m, --kill-server     Terminate the remote server.
 --observe-only        Connect to a server as an observing-only client.
 --status-only         Check the status of the remote bitbake server.
