TAG CLASSES

cc_runtime_deps

Inject extra cc_library deps into the Coco C++ runtime for a specific Coco/Popili version. Root-module only. See the rules_coco README for when this is needed (typically Boost libraries when building against old libstdc++).

Attributes

Name	Description	Type	Mandatory	Default
deps	List of cc_library targets to append to the runtime's deps.	List of labels	required
version	Coco/Popili version these deps apply to. May be an explicit version (e.g. '1.5.1') or an alias (e.g. 'stable').	String	required

toolchain

Name	Description	Type	Mandatory	Default
auth_token_path	Optional path to auth token file for all toolchains when license_source is 'action_file'. The file must be available in the execution environment.	String	optional	""
c	Whether to include C runtime support	Boolean	optional	False
cc	Whether to include C++ runtime support	Boolean	optional	False
license_source	Optional default license source mode for all toolchains (e.g., 'local_user', 'local_acquire', 'token', 'action_environment', 'action_file'). Can be overridden via --@rules_coco//:license_source flag.	String	optional	""
license_token	Optional default license token for all toolchains when license_source is 'token'.	String	optional	""
versions	List of Coco/Popili versions to register (e.g., ['1.5.0', '1.4.0']). Use version aliases like 'stable' or explicit versions like '1.5.1'.	List of strings	optional	["stable"]
