Recipes that 94# call $(MAKE) are classified automatically as recursive; for "build.sh" below, 95# we must mark the recipe manually as recursive, by using the "+" indicator. 96# This way, when the inner "make" starts a parallel build of the target edk2 97# module, it can communicate with the outer "make"'s job server. 98Build/bios-tables-test.%.efi: build-edk2-tools 99 +./build.sh $(edk2_dir) BiosTablesTest $* $@ 100 101build-edk2-tools: 102 $(MAKE) -C $(edk2_dir)/BaseTools \ 103 PYTHON_COMMAND=$${EDK2_PYTHON_COMMAND:-python3} \ 104 EXTRA_OPTFLAGS='$(EDK2_BASETOOLS_OPTFLAGS)' \ 105 EXTRA_LDFLAGS='$(EDK2_BASETOOLS_LDFLAGS)' 106 107clean: 108 rm -rf Build Conf log 109 $(MAKE) -C $(edk2_dir)/BaseTools clean 110
