8 <abstract>ar65 is an archiver for object files generated by ca65. It allows
9 to create archives, add or remove modules from archives, and to extract modules
10 from existing archives.

21 ar65 is a replacement for the libr65 archiver that was part of the cc65 C
22 compiler suite developed by John R. Dunning. libr65 had some problems and
23 the copyright does not permit some things which I wanted to be possible,
24 so I decided to write a completely new assembler/linker/archiver suite
25 for the cc65 compiler. ar65 is part of this suite.
30 The archiver is called as follows:
33 Usage: ar65 <operation> lib file|module ...
37 l List library contents
39 X Print the archiver version
42 You may add modules to a library using the `a' command. If the library
43 does not exist, it is created (and a warning message is printed which you
44 may ignore if creation of the library was your intention). You may
45 specify any number of modules on the command line following the library.
47 If a module with the same name exists in the library, it is replaced by
48 the new one. The archiver prints a warning, if the module in the library
49 has a newer timestamp than the one to add.
54 ar65 a mysubs.lib sub1.o sub2.o
57 This will add two modules to the library `mysubs.lib' creating the
58 library if necessary. If the library contains modules named sub1.o or
59 sub2.o, they are replaced by the new ones.
61 Modules names in the library are stored without the path, so, using
64 ar65 a mysubs.lib ofiles/sub1.o ofiles/sub2.o
67 will add two modules named `sub1.o' and `sub2.o' to the library.
69 Deleting modules from a library is done with the `d' command. You may not
70 give a path when naming the modules.
75 ar65 d mysubs.lib sub1.o
78 This will delete the module named `sub1.o' from the library, printing an
79 error if the library does not contain that module.
82 The `l' command prints a list of all modules in the library. Any module
83 names on the command line are ignored.
92 Using the `x' command, you may extract modules from the library. The
93 modules named on the command line are extracted from the library and put
94 into the current directory.
96 Note: Because of the indexing done by the archiver, the modules may have
97 a changed binary layout, that is, a binary compare with the old module
98 (before importing it into the library) may yield differences. The
99 extracted modules are accepted by the linker and archiver, however, so
100 this is not a problem.
102 Example for extracting a module from the library:
105 ar65 x mysubs.lib sub1.o
109 The `V' command prints the version number of the assembler. If you send
110 any suggestions or bugfixes, please include your version number.
112 In addition to these operations, the archiver will check for, and warn
113 about duplicate external symbols in the library, every time when an
114 operation does update the library. This is only a warning, the linker
115 will ignore one of the duplicate symbols (which one is unspecified).
121 If you have problems using the archiver, if you find any bugs, or if
122 you're doing something interesting with it, I would be glad to hear from
123 you. Feel free to contact me by email (uz@musoftware.de).
