Linker and Utilities
5.12.1 The Library Format
The modules in a library are basically just concatenated, but at the beginning of a library is main-
tained a directory of the modules and symbols in the library. Since this directory is smaller than the
sum of the modules, the linker can perform faster searches since it need read only the directory, and
not all the modules, on the first pass. On the second pass it need read only those modules which are
required, seeking over the others. This all minimises disk I/O when linking.
a general purpose archiving mechanism as is used by some other compiler systems. This has the
advantage that the format may be optimized toward speeding up the linkage process.
5.12.2 Using the Librarian
The librarian program is called LIBR, and the format of commands to it is as follows:
Interpreting this, LIBR is the name of the program, options is zero or more librarian options which
affect the output of the program. k is a key letter denoting the function requested of the librarian
(replacing, extracting or deleting modules, listing modules or symbols), file.lib is the name of
the library file to be operated on, and file.obj is zero or more object file names.
to be replaced or extracted. If no such arguments are supplied, all the modules in the library will be
It should be noted that the library format is geared exclusively toward object modules, and is not
The librarian options are listed in Table 5.2.
The key letters are listed in Table 5.3.
When replacing or extracting modules, the file.obj arguments are the names of the modules
