| <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). |
