Suppose that the configure options 69are <samp><span class="option">--prefix=$prefix --with-system-gdbinit=$prefix/etc/gdbinit</span></samp>; 70if <span class="sc">gdb</span> is moved from <samp><span class="file">$prefix</span></samp> to <samp><span class="file">$install</span></samp>, the system 71init file is looked for as <samp><span class="file">$install/etc/gdbinit</span></samp> instead of 72<samp><span class="file">$prefix/etc/gdbinit</span></samp>. 73 74 <li>By contrast, if the default location does not contain the prefix, 75it will not be relocated. E.g. if <span class="sc">gdb</span> has been configured with 76<samp><span class="option">--prefix=/usr/local --with-system-gdbinit=/usr/share/gdb/gdbinit</span></samp>, 77then <span class="sc">gdb</span> will always look for <samp><span class="file">/usr/share/gdb/gdbinit</span></samp>, 78wherever <span class="sc">gdb</span> is installed. 79</ul> 80 81 </body></html> 82 83
