| 55 | 7.3 Single extension module | |
| 56 | </H1> | |
| 57 | ||
| 58 | <P> | |
| 59 | Extension modules are specified using the <span class="du-option">ext_modules</span> option. | |
| 60 | <span class="du-option">package_dir</span> has no effect on where extension source files are | |
| 61 | found; it only affects the source for pure Python modules. The simplest | |
| 62 | case, a single extension module in a single C source file, is: | |
| 63 | <div class="verbatim"><pre> | |
| 64 | <root>/ | |
| 65 | setup.py | |
| 66 | foo.c | |
| 67 | </pre></div> | |
| 68 | If the <tt class="module">foo</tt> extension belongs in the root package, the setup | |
| 69 | script for this could be | |
| 70 | <div class="verbatim"><pre> | |
| 71 | from distutils.core import setup | |
| 72 | setup(name='foobar', | |
| 73 | version='1.0', | |
| 74 | ext_modules=[Extension('foo', ['foo.c'])], | |
| 75 | ) | |
| 76 | </pre></div> | |
| 77 | ||
| 78 | <P> | |
| 79 | If the extension actually belongs in a package, say <tt class="module">foopkg</tt>, | |
| 80 | then | |
| 81 | ||
| 82 | <P> | |
| 83 | With exactly the same source tree layout, this extension can be put in | |
| 84 | the <tt class="module">foopkg</tt> package simply by changing the name of the | |
| 85 | extension: | |
| 86 | <div class="verbatim"><pre> | |
| 87 | from distutils.core import setup | |
| 88 | setup(name='foobar', | |
| 89 | version='1.0', | |
| 90 | ext_modules=[Extension('foopkg.foo', ['foo.c'])], | |
| 91 | ) | |
| 92 | </pre></div> | |
