'rcS' will case files that has duplicate name been replaced. so on the Mac platform we use 'q' instead of 'r' to achieve an effect similar to '-P' Signed-off-by: xuxin19 <xuxin19@xiaomi.com>

# This is an "ar rcs" equivalent without "no symbols" warnings.
|
|
|
|
# Background:
|
|
#
|
|
# NuttX assumes that it's ok to create
|
|
#
|
|
# - An object without any symbols ("has no symbols")
|
|
# - A library without any symbols ("the table of contents is empty")
|
|
#
|
|
# While macOS's ranlib/libtool can handle those cases,
|
|
# it produces warnings cited in the parentheses.
|
|
# NuttX developers are not happy with those warnings.
|
|
# NuttX developers are not happy with providing per-library dummy
|
|
# objects either.
|
|
#
|
|
# The "has no symbols" warning can be suppressed with
|
|
# the -no_warning_for_no_symbols option if you are using
|
|
# a recent enough version of ranlib/libtool.
|
|
# (Unfortunately, ar doesn't have a way to pass the option to ranlib.)
|
|
# However, there seems to be no way to suppress the
|
|
# "the table of contents is empty" warning. (thus the grep below)
