<!-- man begin DESCRIPTION -->
<p><span class="command">ld</span> combines a number of object and archive files, relocates
their data and ties up symbol references. Usually the last step in
compiling a program is to run <span class="command">ld</span>.
<p><span class="command">ld</span> accepts Linker Command Language files written in
a superset of AT&amp;T's Link Editor Command Language syntax,
to provide explicit and total control over the linking process.
<p>This version of <span class="command">ld</span> uses the general purpose BFD libraries
to operate on object files. This allows <span class="command">ld</span> to read, combine, and
write object files in many different formats&mdash;for example, COFF or
<code>a.out</code>. Different formats may be linked together to produce any
available kind of object file. See <a href="BFD.html#BFD">BFD</a>, for more information.
<p>Aside from its flexibility, the <span class="sc">gnu</span> linker is more helpful than other
linkers in providing diagnostic information. Many linkers abandon
execution immediately upon encountering an error; whenever possible,
<span class="command">ld</span> continues executing, allowing you to identify other errors
(or, in some cases, to get an output file in spite of the error).
