NAME
ar86 - Create, modify, and extract from archive file
SYNOPSIS
ar86 operation archive [file...]
ar86 positional-op member archive [file...]
DESCRIPTION
The ar86 program is used to create, examine and modify archive files
produced by the Dev86/ELKS toolchain.
OPTIONS
The ar86 command requires that the operation to be performed on the
archive be specified as the first option. If the operation is
positional then the next option is the archive member marking the
position. This is followed by the archive file name and any list of
file names.
Operations
One of the following operations can be specified
d delete the listed files from the archive.
m move the named files. By default files are moved to the end of
the archive unless a positional modifier is present.
p print the contents of archive members to standard out. If a file
list is included only those members are printed. If the v
modifier is present each file’s contents are preceeded by a new
line, a line with the string member, a space character, the
member name, and two following newlines.
q quickly add the files to the end of the archive without checking
to see if they already exist in the archive. This operation will
ignore any positional modifiers. Creates the archive file if it
does not exist.
r replace archive members with the files listed. If the file name
is not present in the archive it is added to the end of the
archive (or to any explicitly specified position). Creates the
archive file if it does not exist.
t table; list the file names of archive members. If a file list is
present only those files that are present in the archive are
listed. The v modifier prints member attributes.
x extract the named files from the archive into the current
directory. If no files are specified all the archive members
will be extracted.
Modifiers
The following modifiers may be used with the operations
o original time stamps from the archive are preserved for
extracted files when possible.
s symbol update; this option may be used by itself to force an
update to the symbol definition section of the archive (the
__.SYMDEF member). If any files are specified they will be
replaced as if the r operation had been specified. If no symbol
definition section exists one is created. This option will also
creates the archive file if it does not exist.
u update files in the archive during a r (replace) operation. The
files are added to the archive in exactly the same manner as
replace except that an existing archive member will be retained
(in its original position) if it has a modified more recently
than the file being added. Note that this modifier acts as if a
r operation has been specified (even it has not), and will
actually override any other previously specified operation.
v verbose; print additional diagnostic messages while processing
the archive.
Positional Modifiers
The following modifiers specify where in the archive files are moved to
or added. If any of these modifiers are specified then the second
option to ar86 must be the name of an archive member.
a after; files are placed after the specified archive member.
b before; files are placed before the specified archive member.
i same as b.
EXAMPLES
To see the contents of an archive
ar86 tv libfile.a
To add some files to an archive
ar86 r libfile.a file1.o file2.o
to add some files after a member named mem.o and to update the symbol
table
ar86 rsa mem.o libfile.a file1.o file2.o
BUGS
A l modifier will be accepted but ignored.
RESTRICTIONS
This command is intended for use only with object files created using
the Dev86/ELKS toolchain.
