|
|
<p>Sometimes you want to create a custom Python interpreter with some modules
|
|
built in to the interpreter itself rather than being dynamically loaded. To
|
|
do this the module must be created as a static library and linked with a
|
|
custom stub and the normal Python library.</p>
|
|
<p>To build the SIP module as a static library you must pass the <tt class="docutils literal"><span class="pre">-k</span></tt> command
|
|
line option to <tt class="docutils literal"><span class="pre">configure.py</span></tt>. You should then build and install SIP as
|
|
normal. (Note that, because the module is now a static library, you will not
|
|
be able to import it.)</p>
|
|
<p>To build a module you have created for your own library you must modify your
|
|
own configuration script to pass a non-zero value as the <tt class="docutils literal"><span class="pre">static</span></tt> argument
|
|
of the <tt class="docutils literal"><span class="pre">__init__()</span></tt> method of the <a title="sipconfig.ModuleMakefile" class="reference external" href="build_system.html#sipconfig.ModuleMakefile"><tt class="xref docutils literal"><span class="pre">sipconfig.ModuleMakefile</span></tt></a> class (or
|
|
any derived class you have created). Normally you would make this configurable
|
|
using a command line option in the same way that SIP’s <tt class="docutils literal"><span class="pre">configure.py</span></tt> handles
|
|
it.</p>
|
|
<p>The next stage is to create a custom stub and a Makefile. The SIP distribution
|
|
contains a directory called <tt class="docutils literal"><span class="pre">custom</span></tt> which contains example stubs and a
|
|
Python script that will create a correct Makefile. Note that, if your copy of
|
|
SIP was part of a standard Linux distribution, the <tt class="docutils literal"><span class="pre">custom</span></tt> directory may
|
|
not be installed on your system.</p>
|
|
<p>The <tt class="docutils literal"><span class="pre">custom</span></tt> directory contains the following files. They are provided as
|
|
examples - each needs to be modified according to your particular
|
|
requirements.</p>
|
|
<blockquote>
|
|
<ul class="simple">
|
|
<li><tt class="docutils literal"><span class="pre">mkcustom.py</span></tt> is a Python script that will create a Makefile which is
|
|
then used to build the custom interpreter. Comments in the file describe
|
|
how it should be modified.</li>
|
|
<li><tt class="docutils literal"><span class="pre">custom.c</span></tt> is a stub for a custom interpreter on Linux/UNIX. It
|
|
should also be used for a custom console interpreter on Windows (i.e.
|
|
like <tt class="docutils literal"><span class="pre">python.exe</span></tt>). Comments in the file describe how it should be
|
|
modified.</li>
|
|
<li><tt class="docutils literal"><span class="pre">customw.c</span></tt> is a stub for a custom GUI interpreter on Windows (i.e.
|
|
like <tt class="docutils literal"><span class="pre">pythonw.exe</span></tt>). Comments in the file describe how it should be
|
|
modified.</li>
|
|
</ul>
|
|
</blockquote>
|
|
<p>Note that this technique does not restrict how the interpreter can be used.
|
|
For example, it still allows users to write their own applications that can
|
|
import your builtin modules. If you want to prevent users from doing that,
|
|
perhaps to protect a proprietary API, then take a look at the
