ranlib
creates an index of external references for archive libraries,
normally used by the loader,
ld(1).
This index file is named
“/”
or
“__.SYMDEF”
and is prepended to the archive.
Files in the archive which are not executable and symbols which are
uninteresting to the loader are ignored.
The options are as follows:
-t
Set the modification time of the index file.
This time is compared by the loader with the modification time of the
archive to verify that the table is up-to-date with respect to the
archive.
If the modification time has been changed without any change to the
archive (for example, by a
cp(1/)),
the
-t
option can be used to
“touch”
the modification time so that it appears that the table is up-to-date.
This is also useful after using the
-t
option of
make(1).
ENVIRONMENT
TMPDIR
The pathname of the directory to use when creating temporary files.
