The `arguments` are a list of build sets to build.

Options:

`--force`:

  Force the build to proceed even if the host check fails. Typically this happens if executable files are found in the path at a different location to the host defaults.

`--trace`:

  Trace enable printing of debug information to stdout. It is really only of use to RTEMS Source Builder’s developers.

`--dry-run`:

  Do everything but actually run the build commands. This is useful when checking a new configuration parses cleanly.

`--warn-all`:

  Generate warnings.

`--no-clean`:

  Do not clean up the build tree during the cleaning phase of the build. This leaves the source and the build output on disk so you can make changes, or amend or generate new patches. It also allows you to review configure type output such as `config.log`.

`--always-clean`:

  Clean away the results of a build even if the build fails. This is normally used with `--keep-going` when regression testing to see which build sets fail to build. It keeps the disk usage down.

`--jobs`:

  Control the number of jobs make is given. The jobs can be `none` for only 1 job, `half` so the number of jobs is half the number of detected cores, a fraction such as `0.25` so the number of jobs is a quarter of the number of detected cores and a number such as `25` which forces the number of jobs to that number.

`--host`:

  Set the host triplet value. Be careful with this option.

`--build`:

  Set the build triplet. Be careful with this option.

`--target`:

  Set the target triplet. Be careful with this option. This is useful if you have a generic configuration script that can work for a range of architectures.

`--prefix path`:

  Tools build prefix, ie where they are installed.

`--topdir path`:

  Top of the build tree, that is the current directory you are in.

`--configdir path`:

  Path to the configuration directory. This overrides the built in defaults.

`--builddir path`:

  Path to the build directory. This overrides the default of build.

`--sourcedir path`:

  Path to the source directory. This overrides the default of source.

`--patchdir path`:

  Path to the patches directory. This overrides the default of patches.

`--tmppath path`:

  Path to the temporary directory. This overrides the default of tmp.

`--macros files`:

  Macro files to load. The configuration directory path is searched.

`--log file`:

  Log all the output from the build process. The output is directed to stdout if no log file is provided.

`--url url`:

  URL to look for source when downloading. This is can be comma separate list.

`--no-download`:

  Disable downloading of source and patches. If the source is not found an error is raised.

`--targetcflags flags`:

  List of C flags for the target code. This allows for specific local customisation when testing new variations.

`--targetcxxflags flags`:

  List of C++ flags for the target code. This allows for specific local customisation when testing new variations.

`--libstdcxxflags flags`:

  List of C++ flags to build the target libstdc++ code. This allows for specific local customisation when testing new variations.

`--with-<label>`:

  Add the `--with-<label>` to the build. This can be tested for in a script with the `%bconf_with` macro.

`--without-<label>`:

  Add the `--without-<label>` to the build. This can be tested for in a script with the `%bconf_without` macro.

`--mail-from`:

  Set the from mail address if report mailing is enabled.

`--mail-to`:

  Set the to mail address if report mailing is enabled. The report is mailed to this address.

`--mail`:

  Mail the build report to the mail to address.

`--smtp-host`:

  The SMTP host to use to send the email. The default is `localhost`.

`--no-report`:

  Do not create a report format.

`--report-format format`:

  The report format can be `text` or `html`. The default is `html`.

`--keep-going`:

  Do not stop on error. This is useful if your build sets performs a large number of testing related builds and there are errors.

`--always-clean`:

  Always clean the build tree even with a failure.

`--no-install`:

  Do not install the packages to the prefix. Use this if you are only after the tar files.

`--regression`:

  A convenience option which is the same as `--no-install`, `--keep-going` and `--always-clean`.

`--bset-tar-file`:

  Create a build set tar file. This is a single tar file of all the packages in the build set.

`--pkg-tar-files`:

  Create package tar files. A tar file will be created for each package built in a build set.

`--list-bsets`:

  List available build sets.

`--list-configs`:

  List available configurations.

`--list-deps`:

  Print a list of dependent files used by a build set. Dependent files have a `dep[?]` prefix where ``?` is a number. The files are listed alphabetically.

## 13.6.4. Set Builder (sb-builder)

This command builds a configuration as described in a configuration file. Configuration files have the extension of `.cfg`:
