<screen><userinput>CXX="/usr/bin/g++"                     \

    <para>
      <command> CXX="/usr/bin/g++" ./configure ...</command>: Avoid an annoying
      message during configuration.
    </para>

    <para>
      <parameter>--prefix=/opt/python3.11</parameter>: This installs python
      3.11 into /opt in order to avoid conflicts with the system version of
      python, and allows for easy removal/isolation once programs update to
      python3.12 or later.
    </para>

    <para>
      <parameter>--disable-shared</parameter>: This switch disables building
      shared libraries. Since all the packages that need python-3.11 have built
      in modules and don't directly link to python, it is safe to turn off
      shared library support.
    </para>

    <para>
      <parameter>--with-system-expat</parameter>: This switch enables linking
      against the system version of <application>Expat</application>.
