.SH NAME

.SH SYNOPSIS
|
|
.IX Header "SYNOPSIS"
|
|
ranlib [\fB\-\-plugin\fR \fIname\fR] [\fB\-DhHvVt\fR] \fIarchive\fR
|
|
.SH DESCRIPTION
|
|
.IX Header "DESCRIPTION"
|
|
\&\fBranlib\fR generates an index to the contents of an archive and
|
|
stores it in the archive. The index lists each symbol defined by a
|
|
member of an archive that is a relocatable object file.
|
|
.PP
|
|
You may use \fBnm \-s\fR or \fBnm \-\-print\-armap\fR to list this index.
|
|
.PP
|
|
An archive with such an index speeds up linking to the library and
|
|
allows routines in the library to call each other without regard to
|
|
their placement in the archive.
|
|
.PP
|
|
The GNU \fBranlib\fR program is another form of GNU \fBar\fR; running
|
|
\&\fBranlib\fR is completely equivalent to executing \fBar \-s\fR.

Show the version number of \fBranlib\fR.
|
|
.IP \fB\-D\fR 4
|
|
.IX Item "-D"
|
|
Operate in \fIdeterministic\fR mode. The symbol map archive member's
|
|
header will show zero for the UID, GID, and timestamp. When this
|
|
option is used, multiple runs will produce identical output files.
|
|
.Sp
|
|
If \fIbinutils\fR was configured with
|
|
\&\fB\-\-enable\-deterministic\-archives\fR, then this mode is on by
|
|
default. It can be disabled with the \fB\-U\fR option, described
|
|
below.
|
|
.IP \fB\-t\fR 4
|
|
.IX Item "-t"
|
|
Update the timestamp of the symbol map of an archive.
|
|
.IP \fB\-U\fR 4
|
|
.IX Item "-U"
|
|
Do \fInot\fR operate in \fIdeterministic\fR mode. This is the
|
|
inverse of the \fB\-D\fR option, above: the archive index will get
|
|
actual UID, GID, timestamp, and file mode values.
|
|
.Sp
|
|
If \fIbinutils\fR was configured \fIwithout\fR
|
|
\&\fB\-\-enable\-deterministic\-archives\fR, then this mode is on by
|
|
default.
|
|
.IP \fB@\fR\fIfile\fR 4
|
|
.IX Item "@file"
|
|
Read command-line options from \fIfile\fR. The options read are
|
|
inserted in place of the original @\fIfile\fR option. If \fIfile\fR
|
|
does not exist, or cannot be read, then the option will be treated
|
|
literally, and not removed.
|
|
.Sp
|
|
Options in \fIfile\fR are separated by whitespace. A whitespace
|
|
character may be included in an option by surrounding the entire
|
|
option in either single or double quotes. Any character (including a
|
|
backslash) may be included by prefixing the character to be included
|
|
with a backslash. The \fIfile\fR may itself contain additional
|
|
@\fIfile\fR options; any such options will be processed recursively.
