Operation is one of: a Add modules d Delete modules l List library contents x Extract modules V Print the archiver version</PRE></CODE></BLOCKQUOTE></P><P>You may add modules to a library using the `a' command. If the librarydoes not exist, it is created (and a warning message is printed which youmay ignore if creation of the library was your intention). You mayspecify any number of modules on the command line following the library.</P><P>If a module with the same name exists in the library, it is replaced bythe new one. The archiver prints a warning, if the module in the libraryhas a newer timestamp than the one to add.</P><P>Here's an example:</P><P><BLOCKQUOTE><CODE><PRE> ar65 a mysubs.lib sub1.o sub2.o</PRE></CODE></BLOCKQUOTE></P><P>This will add two modules to the library `mysubs.lib' creating thelibrary if necessary. If the library contains modules named sub1.o orsub2.o, they are replaced by the new ones.</P><P>Modules names in the library are stored without the path, so, using</P><P><BLOCKQUOTE><CODE><PRE> ar65 a mysubs.lib ofiles/sub1.o ofiles/sub2.o</PRE></CODE></BLOCKQUOTE></P><P>will add two modules named `sub1.o' and `sub2.o' to the library.</P><P>Deleting modules from a library is done with the `d' command. You may notgive a path when naming the modules.</P><P>Example:</P><P><BLOCKQUOTE><CODE><PRE> ar65 d mysubs.lib sub1.o</PRE></CODE></BLOCKQUOTE></P><P>This will delete the module named `sub1.o' from the library, printing anerror if the library does not contain that module.</P><P>The `l' command prints a list of all modules in the library. Any modulenames on the command line are ignored.</P><P>Example:</P><P><BLOCKQUOTE><CODE><PRE> ar65 l mysubs.lib</PRE></CODE></BLOCKQUOTE></P><P>Using the `x' command, you may extract modules from the library. Themodules named on the command line are extracted from the library and putinto the current directory.</P><P>Note: Because of the indexing done by the archiver, the modules may havea changed binary layout, that is, a binary compare with the old module(before importing it into the library) may yield differences. Theextracted modules are accepted by the linker and archiver, however, sothis is not a problem.</P><P>Example for extracting a module from the library:</P><P><BLOCKQUOTE><CODE><PRE> ar65 x mysubs.lib sub1.o</PRE></CODE></BLOCKQUOTE></P><P>The `V' command prints the version number of the assembler. If you sendany suggestions or bugfixes, please include your version number.</P><P>In addition to these operations, the archiver will check for, and warnabout duplicate external symbols in the library, every time when anoperation does update the library. This is only a warning, the linkerwill ignore one of the duplicate symbols (which one is unspecified).</P><HR><A HREF="ar65-3.html">Next</A><A HREF="ar65-1.html">Previous</A><A HREF="ar65.html#toc2">Contents</A></BODY></HTML>?? 快捷鍵說明
