| 56 | 1.5 Compilation and Linkage | |
| 57 | ||
| 58 | </H1> | |

| 60 | <P> | |
| 61 | There are two more things to do before you can use your new extension: | |
| 62 | compiling and linking it with the Python system. If you use dynamic | |
| 63 | loading, the details may depend on the style of dynamic loading your | |
| 64 | system uses; see the chapters about building extension modules | |
| 65 | (chapter <A href="building.html#building">3</A>) and additional information that pertains only | |
| 66 | to building on Windows (chapter <A href="building-on-windows.html#building-on-windows">4</A>) for more | |
| 67 | information about this. | |
| 68 | ||
| 69 | <P> | |
| 70 | If you can't use dynamic loading, or if you want to make your module a | |
| 71 | permanent part of the Python interpreter, you will have to change the | |
| 72 | configuration setup and rebuild the interpreter. Luckily, this is | |
| 73 | very simple on <span class="Unix">Unix</span>: just place your file (<span class="file">spammodule.c</span> for | |
| 74 | example) in the <span class="file">Modules/</span> directory of an unpacked source | |
| 75 | distribution, add a line to the file <span class="file">Modules/Setup.local</span> | |
| 76 | describing your file: | |
| 77 | ||
| 78 | <P> | |
| 79 | <div class="verbatim"><pre> | |
| 80 | spam spammodule.o | |
| 81 | </pre></div> | |
| 82 | ||
| 83 | <P> | |
| 84 | and rebuild the interpreter by running <b class="program">make</b> in the toplevel | |
| 85 | directory. You can also run <b class="program">make</b> in the <span class="file">Modules/</span> | |
| 86 | subdirectory, but then you must first rebuild <span class="file">Makefile</span> | |
| 87 | there by running `<b class="program">make</b> Makefile'. (This is necessary each | |
| 88 | time you change the <span class="file">Setup</span> file.) | |
| 89 | ||
| 90 | <P> | |
| 91 | If your module requires additional libraries to link with, these can | |
| 92 | be listed on the line in the configuration file as well, for instance: | |
| 93 | ||
| 94 | <P> | |
| 95 | <div class="verbatim"><pre> | |
| 96 | spam spammodule.o -lX11 | |
| 97 | </pre></div> | |
