ar65 is an archiver for object files generated by ca65. It allows to create
|
|
archives, add or remove modules from archives, and to extract modules from
|
|
existing archives.

<sect>Overview<p>
|
|
|
|
|
|
ar65 is a replacement for the libr65 archiver that was part of the cc65 C
|
|
compiler suite developed by John R. Dunning. libr65 had some problems and
|
|
the copyright does not permit some things which I wanted to be possible,
|
|
so I decided to write a completely new assembler/linker/archiver suite
|
|
for the cc65 compiler. ar65 is part of this suite.
|
|
|
|
<sect>Usage<p>
|
|
|
|
|
|
The archiver is called as follows:
|
|
|
|
<tscreen><verb>
|
|
Usage: ar65 <operation> lib file|module ...
|
|
Operation is one of:
|
|
a Add modules
|
|
d Delete modules
|
|
l List library contents
|
|
x Extract modules
|
|
V Print the archiver version
|
|
</verb></tscreen>
|
|
|
|
You may add modules to a library using the `a' command. If the library
|
|
does not exist, it is created (and a warning message is printed which you
|
|
may ignore if creation of the library was your intention). You may
|
|
specify any number of modules on the command line following the library.
|
|
|
|
If a module with the same name exists in the library, it is replaced by
|
|
the new one. The archiver prints a warning, if the module in the library
|
|
has a newer timestamp than the one to add.
|
|
|
|
Here's an example:
|
|
|
|
<tscreen><verb>
|
|
ar65 a mysubs.lib sub1.o sub2.o
|
|
</verb></tscreen>
|
|
|
|
This will add two modules to the library `mysubs.lib' creating the
|
|
library if necessary. If the library contains modules named sub1.o or
|
|
sub2.o, they are replaced by the new ones.
|
|
|
|
Modules names in the library are stored without the path, so, using
|
|
|
|
<tscreen><verb>
|
|
ar65 a mysubs.lib ofiles/sub1.o ofiles/sub2.o
|
|
</verb></tscreen>
|
|
|
|
will add two modules named `sub1.o' and `sub2.o' to the library.
|
|
|
|
Deleting modules from a library is done with the `d' command. You may not
|
|
give a path when naming the modules.
|
|
|
|
Example:
|
|
|
|
<tscreen><verb>
|
|
ar65 d mysubs.lib sub1.o
|
|
</verb></tscreen>
|
|
|
|
This will delete the module named `sub1.o' from the library, printing an
|
|
error if the library does not contain that module.
|
|
|
|
|
|
The `l' command prints a list of all modules in the library. Any module
|
|
names on the command line are ignored.
|
|
|
|
Example:
|
|
|
|
<tscreen><verb>
|
|
ar65 l mysubs.lib
|
|
</verb></tscreen>
|
|
|
|
|
|
Using the `x' command, you may extract modules from the library. The
|
|
modules named on the command line are extracted from the library and put
|
|
into the current directory.
|
|
|
|
Note: Because of the indexing done by the archiver, the modules may have
|
|
a changed binary layout, that is, a binary compare with the old module
|
|
(before importing it into the library) may yield differences. The
|
|
extracted modules are accepted by the linker and archiver, however, so
|
|
this is not a problem.
|
|
|
|
Example for extracting a module from the library:
|
|
|
|
<tscreen><verb>
|
|
ar65 x mysubs.lib sub1.o
|
|
</verb></tscreen>
|
|
|
|
|
|
The `V' command prints the version number of the assembler. If you send
|
|
any suggestions or bugfixes, please include your version number.
|
|
|
|
In addition to these operations, the archiver will check for, and warn
|
|
about duplicate external symbols in the library, every time when an
|
|
operation does update the library. This is only a warning, the linker
|
|
will ignore one of the duplicate symbols (which one is unspecified).
|
|
|
|
|
|
<sect>Bugs/Feedback<p>
|
|
|
|
If you have problems using the archiver, if you find any bugs, or if you're
|
|
doing something interesting with it, I would be glad to hear from you. Feel
|
|
free to contact me by email (<htmlurl url="mailto:uz@cc65.org" name="uz@cc65.org">).
