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> | |
