From: Mahesh Kumar Kalikot Veetil <mkalikot@xxxxxxxxxxxxxx> Modules with a large number of compilation units may be exceeding AR and LD command argument list. Handle this gracefully by writing the long argument list in a file. The command line options read from file are inserted in place of the original @file option. The usage is well documented at https://www.gnu.org/software/make/manual/html_node/File-Function.html Signed-off-by: Mahesh Kumar Kalikot Veetil <mkalikot@xxxxxxxxxxxxxx> Signed-off-by: Jeff Johnson <jjohnson@xxxxxxxxxxxxxx> --- scripts/Makefile.build | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) diff --git a/scripts/Makefile.build b/scripts/Makefile.build index 252b7d2..d5ef345 100644 --- a/scripts/Makefile.build +++ b/scripts/Makefile.build @@ -425,7 +425,11 @@ $(obj)/lib.a: $(lib-y) FORCE # module is turned into a multi object module, $^ will contain header file # dependencies recorded in the .*.cmd file. quiet_cmd_link_multi-m = LD [M] $@ - cmd_link_multi-m = $(LD) $(ld_flags) -r -o $@ $(filter %.o,$^) + cmd_link_multi-m = \ + $(file >$@.in,$(filter %.o,$^)) \ + $(LD) $(ld_flags) -r -o $@ @$@.in; \ + rm -f $@.in +endif $(multi-used-m): FORCE $(call if_changed,link_multi-m) -- The Qualcomm Innovation Center, Inc. is a member of the Code Aurora Forum, a Linux Foundation Collaborative Project
