Here is a warning which I found in the 'make' process of
ar: `u' modifier ignored since `D' is the default (see `U')
According to the 'man ar' page:
D Operate in deterministic mode. When adding files and the archive
index use zero for UIDs, GIDs, timestamps, and use consistent file
modes for all files. When this option is used, if ar is used with
identical options and identical input files, multiple runs will
create identical output files regardless of the input files'
owners, groups, file modes, or modification times.
If binutils was configured with --enable-deterministic-archives,
then this mode is on by default. It can be disabled with the U
u Normally, ar r... inserts all files listed into the archive. If
you would like to insert only those of the files you list that are
newer than existing members of the same names, use this modifier.
The u modifier is allowed only for the operation r (replace). In
particular, the combination qu is not allowed, since checking the
timestamps would lose any speed advantage from the operation q.
U Do not operate in deterministic mode. This is the inverse of the D
modifier, above: added files and the archive index will get their
actual UID, GID, timestamp, and file mode values.
This is the default unless binutils was configured with
