fab.steps.link

Link an executable.

Functions

link_exe(config[, flags, source])	Link object files into an executable for every build target.
link_shared_object(config, output_fpath[, ...])	Produce a shared object (.so) file from the given build target.

Classes

DefaultLinkerSource()

A source getter specifically for linking.

class fab.steps.link.DefaultLinkerSource

A source getter specifically for linking. Looks for the default output from archiving objects, falls back to default compiler output. This allows a link step to work with or without a preceding object archive step.

fab.steps.link.link_exe(config, flags=None, source=None)

Link object files into an executable for every build target.

Expects one or more build targets from its artefact getter, of the form Dict[name, object_files].

The default artefact getter, DefaultLinkerSource, looks for any output from an ArchiveObjects step, and falls back to using output from compiler steps.

Parameters:

• config – The fab.build_config.BuildConfig object where we can read settings such as the project workspace folder or the multiprocessing flag.

• flags – A list of flags to pass to the linker. (default: None)

• source (Optional[ArtefactsGetter]) – An optional ArtefactsGetter. It defaults to the output from compiler steps, which typically is the expected behaviour. (default: None)

fab.steps.link.link_shared_object(config, output_fpath, flags=None, source=None)

Produce a shared object (.so) file from the given build target.

Expects a single build target from its artefact getter, of the form Dict[None, object_files]. We can assume the list of object files is the entire project source, compiled.

Params are as for LinkerBase, with the addition of:

Parameters:

• config – The fab.build_config.BuildConfig object where we can read settings such as the project workspace folder or the multiprocessing flag.

• output_fpath (str) – File path of the shared object to create.

• flags – A list of flags to pass to the linker. (default: None)

• source (Optional[ArtefactsGetter]) – An optional ArtefactsGetter. Typically not required, as there is a sensible default. (default: None)
