<p>So to use this extension mechanism your platform has to support the DSO
- feature and your Apache <code>httpd</code> binary has to be built with the
+ feature and your Apache <program>httpd</program> binary has to be built with the
<module>mod_so</module> module. The <code>apxs</code> tool automatically
complains if this is not the case. You can check this yourself by manually
running the command</p>
<module>mod_so</module> or perhaps even read the
<code>src/modules/standard/mod_so.c</code> source file.</p>

- <p>You can even use <code>apxs</code> to compile complex modules outside the
- Apache source tree, like PHP3:</p>
-
- <example>
- $ cd php3<br />
- $ ./configure --with-shared-apache=../apache-1.3<br />
- $ apxs -c -o libphp3.so mod_php3.c libmodphp3-so.a<br />
- gcc -fpic -DSHARED_MODULE -I/tmp/apache/include -c mod_php3.c<br />
- ld -Bshareable -o libphp3.so mod_php3.o libmodphp3-so.a<br />
- $ _
- </example>
-
- <p>because <code>apxs</code> automatically recognized C source files and
- object files. Only C source files are compiled while remaining object
- files are used for the linking phase.</p>
