Due to that, nothing needs to be set # for an external executable in the typical case. # # All external executables must be registered (by listing the executable # name in gb_ExternalExecutable_register_executables call). This is done in # Repository.mk . # # === Usage === # # The call site(s) should always use both of the following functions: # * gb_ExternalExecutable_get_command: the complete command for the # executable # * gb_ExternalExecutable_get_dependencies: all run-time dependencies # needed by the command. ## Infrastructure functions # The list of registered executables. gb_ExternalExecutable_REGISTERED_EXECUTABLES := define gb_ExternalExecutable__add_executable $(if $(filter $(executable),$(gb_ExternalExecutable_REGISTERED_EXECUTABLES)),\ $(call gb_Output_error,external executable $(executable) has already been registered) \ ) gb_ExternalExecutable_REGISTERED_EXECUTABLES += $(1) endef # Register one or more external executables. # # gb_ExternalExecutable_register_executables executable(s) define gb_ExternalExecutable_register_executables $(foreach executable,$(1),$(call gb_ExternalExecutable__add_executable,$(executable))) endef define gb_ExternalExecutable__process_registration $(if $(filter undefined,$(origin gb_ExternalExecutable__register_$(executable))),\ $(call gb_Output_error,there is no definition for external executable $(executable)) \ ) $(call gb_ExternalExecutable__register_$(executable)) endef # Collect definitions for registered executables. # # The registration functions will be run. # # gb_ExternalExecutable_collect_registrations define gb_ExternalExecutable_collect_registrations $(eval $(foreach executable,$(gb_ExternalExecutable_REGISTERED_EXECUTABLES),\ $(call gb_ExternalExecutable__process_registration,$(executable))) ) endef define gb_ExternalExecutale__check_registration $(if $(filter $(1),$(gb_ExternalExecutable_REGISTERED_EXECUTABLES)),,\ $(call gb_Output_error,external executable $(1) has not been registered) \ ) endef ## Setup functions # Set the executable as external # # Optionally set a specific executable call to use. # Example: # $(call gb_ExternalExecutable_set_external,genbrk,$(SYSTEM_GENBRK)) # # gb_ExternalExecutable_set_external executable call? define gb_ExternalExecutable_set_external $(if $(2),gb_ExternalExecutable_$(1)_EXECUTABLE := $(2)) endef # FIXME need to subst in some more $$ in gb_Helper_set_ld_path here - ugly # but other uses (gb_CppunitTest_CPPTESTPRECOMMAND) require less $$ - ugly define gb_ExternalExecutable__set_internal $(if $(3),,$(if $(filter $(WORKDIR_FOR_BUILD)/UnpackedTarball,$(2)),\ $(call gb_Output_error,depending directly on executable $(2) from UnpackedTarball is not allowed.
