10 ar65 is an archiver for object files generated by ca65. It allows to create
11 archives, add or remove modules from archives, and to extract modules from
15 <!-- Table of contents -->

23 ar65 is a replacement for the libr65 archiver that was part of the cc65 C
24 compiler suite developed by John R. Dunning. libr65 had some problems and
25 the copyright does not permit some things which I wanted to be possible,
26 so I decided to write a completely new assembler/linker/archiver suite
27 for the cc65 compiler. ar65 is part of this suite.
32 The archiver is called as follows:
35 Usage: ar65 <operation ...> lib file|module ...
36 Operations are some of:
40 v Increase verbosity (put before other operation)
42 V Print the archiver version
45 You may add modules to a library using the `r' command (`a' is deprecated). If the library
46 does not exist, it is created (and a warning message is printed which you
47 may ignore if creation of the library was your intention). You may
48 specify any number of modules on the command line following the library.
50 If a module with the same name exists in the library, it is replaced by
51 the new one. The archiver prints a warning, if the module in the library
52 has a newer timestamp than the one to add.
57 ar65 r mysubs.lib sub1.o sub2.o
60 This will add two modules to the library `mysubs.lib' creating the
61 library if necessary. If the library contains modules named sub1.o or
62 sub2.o, they are replaced by the new ones.
64 Modules names in the library are stored without the path, so, using
67 ar65 v v r mysubs.lib ofiles/sub1.o ofiles/sub2.o
70 will verbose add two modules named `sub1.o' and `sub2.o' to the library.
72 Deleting modules from a library is done with the `d' command. You may not
73 give a path when naming the modules.
78 ar65 d mysubs.lib sub1.o
81 This will delete the module named `sub1.o' from the library, printing an
82 error if the library does not contain that module.
85 The `t' command prints a table of all modules in the library (`l' is deprecated).
86 Any module names on the command line are ignored.
95 Using the `x' command, you may extract modules from the library. The
96 modules named on the command line are extracted from the library and put
97 into the current directory.
99 Note: Because of the indexing done by the archiver, the modules may have
100 a changed binary layout, that is, a binary compare with the old module
101 (before importing it into the library) may yield differences. The
102 extracted modules are accepted by the linker and archiver, however, so
103 this is not a problem.
105 Example for extracting a module from the library:
108 ar65 x mysubs.lib sub1.o
112 The `V' command prints the version number of the assembler. If you send
113 any suggestions or bugfixes, please include your version number.
115 In addition to these operations, the archiver will check for, and warn
116 about duplicate external symbols in the library, every time when an
117 operation does update the library. This is only a warning, the linker
118 will ignore one of the duplicate symbols (which one is unspecified).
