The semantic of .NOPARALLEL has changed in GNU Make 4.4 Quote: New feature: .NOTPARALLEL accepts prerequisites If the .NOTPARALLEL special target has prerequisites then all prerequisites of those targets will be run serially (as if .WAIT was specified between each prerequisite). This means that only prerequisites are made sequential. Before everything within a Makefile would be done in sequential order. Therefore, we had to add the *.hash target (appears multiple times) to the .NOPARALLEL prerequisites. issue #4725

# \brief Rule for populating an archive by evaluating a content.mk file
|
|
# \author Norman Feske

# \date 2017-03-17
|
|
#
|
|
# This file complements 'create.inc' for the creation of API and source
|
|
# archives.
|
|
#
|
|
# Arguments:
|
|
#
|
|
# RECIPE_DIR - location of the recipe for the source or API archive
|
|
# DEPOT_ARCHIVE_DIR - archive destination within the depot
|
|
# TAG_FILE - file within archive used as tag for make dependencies
|
|
# GENODE_DIR - root of the Genode source tree
|
|
# REP_DIR - source repository where 'RECIPE_DIR' is located
|
|
#
|
|
|
|
#
|
|
# Validate existance of a content.mk file for the archive recipe
|
|
#
|
|

|
EXPECTED_CONTENT_MK_FILE := $(RECIPE_DIR)/content.mk

|
checked_content_mk_exists: checked_recipe_is_unique

|
ifeq ($(CONTENT_MK_FILE),)
|
|
@$(ECHO) "Error: Recipe misses content.mk file,\n" \
|
|
" expected at '$(EXPECTED_CONTENT_MK_FILE)'"; false
|
|
endif
|
|
|
|
$(TARGET) $(DEPOT_ARCHIVE_DIR)/$(TAG_FILE): checked_content_mk_exists
|
|
|
|
#
|
|
# Handle the creation of the TAG_FILE (and the population of the archive
|
|
# directory as its side effect) as an atomic step. Otherwise a dependent
|
|
# rule - in particular the rule for generating the hash - could be
|
|
# triggered as soon as the specific tag file appears but before the entire
|
|
# sub make is finished with populating the archive directory.
|
|
#
|
|

|
|
|
|
#
|
|
# Assemble archive content by invoking the recipe's content.mk file
|
|
#
|
|
# If an error (such as a missing installation of a port) occurs during this
|
|
# step, remove the incomplete archive before returning an error.
