<p><code>ld</code> 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 <code>ld</code>.
|
||
|
|
</p>
|
||
|
|
<p><code>ld</code> accepts Linker Command Language files written in
|
||
|
|
a superset of AT&T’s Link Editor Command Language syntax,
|
||
|
|
to provide explicit and total control over the linking process.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<p>This version of <code>ld</code> uses the general purpose BFD libraries
|
||
|
|
to operate on object files. This allows <code>ld</code> to read, combine, and
|
||
|
|
write object files in many different formats—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>
|
||
|
|
<p>Aside from its flexibility, the <small>GNU</small> linker is more helpful than other
|
||
|
|
linkers in providing diagnostic information. Many linkers abandon
|
||
|
|
execution immediately upon encountering an error; whenever possible,
|
||
|
|
<code>ld</code> continues executing, allowing you to identify other errors
|
||
|
|
(or, in some cases, to get an output file in spite of the error).
