171 | <para>By default, the dynamic loader (<filename |

173 | <filename class="directory">/lib</filename> and <filename |

174 | class="directory">/usr/lib</filename> for dynamic libraries that are |

175 | needed by programs as they are run. However, if there are libraries in |
---|
176 | directories other than <filename class="directory">/lib</filename> and |

177 | <filename class="directory">/usr/lib</filename>, these need to be |
---|
178 | added to the <filename>/etc/ld.so.conf</filename> file in order |
---|
179 | for the dynamic loader to find them. Two directories that are commonly |

180 | known to contain additional libraries are <filename |

181 | class="directory">/usr/local/lib</filename> and <filename |

182 | class="directory">/opt/lib</filename>, so add those directories to the |
