These are coveredseparately.<h2>Uninstalling TinyOS 1.0, or hand-built install</h2>On Windows, if you installed using the Installshield Wizard, usethe Remove option under Add/Remove Programs -- save your workfirst. Don't worry about incomplete removal, but do delete any leftover files.<br><br>If you use Linux, didn't use the installshield, or installshieldremoval failed, remove the following items manually:<br><ul> <li><a href="#cygwin">cygwin</a> (Windows only)</li> <li>avr-gcc, avr-binutils, avr-libc (possibly the WinAVR package onWindows, possibly some rpms)</li> <li>previous versions of nesC</li> <li>previous versions of uisp</li></ul><h4><a name="cygwin"></a>Cygwin Uninstallation</h4>Remove the following items to fully uninstall cygwin:<br><ul> <li>Cygwin shortcuts and start menu entry (Programs/Cygwin)</li> <li>Cygwin registry entries under <span style="font-family: monospace;">HKEY_LOCAL_MACHINE\SoftWare\CygnusSolutions\ </span>(run <span style="font-family: monospace;">regedit</span>or <span style="font-family: monospace;">regedt32</span> to remove these) </li> <li>Everything under the cygwin root directory. Save useful files ofcourse... you could just rename the cygwin root to say, cygwin-old, tobe extra safe.</li></ul><h2>Unistalling TinyOS 1.1 or later</h2>On Windows, if you used the InstallShield Wizard, you can just use theRemove option under Add/Remove Programs. See the discussion below onwhat to do if this fails (which shouldn't happen under normalcircumstances, but can occur after failed installations or if some filesare moved manually after installation).<br><br>On Linux, and on Windows when not using the installshield, you cansimply remove all the rpms (with explicit <span style="font-family: monospace;">rpm -e</span> commands). On Windows,you might want to remove cygwin too (see <a href="#cygwin">cygwinuninstallation</a>).<br><br>In all cases, you may find some files left behind in <span style="font-family: monospace;">/opt/tinyos-1.x</span> or <span style="font-family: monospace;"><installationroot>\cygwin\opt\tinyos-1.x</span>, you can delete these if you wish.<br><h4>HOW TO RECOVER FROM INCOMPLETE TinyOS 1.1 INSTALLSHIELD UNINSTALLS</h4>It is possible for the TinyOS setup to enter a mode where it attemptsan uninstall, fails for some reason (most often the cygwin directoryhas been moved since installation, and now it cannot be found touninstall the TinyOS RPMs), yet remains installed. Sometimes theInstallshield setup will fail during installation for some reason(perhaps because the user had insufficient privileges, forexample). Sometimes the Add/Remove Programs uninstall does notcomplete. In either case, the end result is that the setupcontinues to attempt uninstall, fails, attempts uninstall, fails,attempts uninstall...<br><br>One way to recover from this state is to reinstall cygwin manually sothat the uninstallation can succeed, complete the uninstallation, andthen re-install TinyOS. You can do this as follows:<br><ol> <li>Don't worry about older, incomplete tinyos-1.x version (1.0)uninstalls</li> <li>Delete all previous tools (see list above) </li> <li>(Re)install cygwin. You can download the cygwin setup programused for TinyOS 1.1.0 from </li> <li><a href="http://webs.cs.berkeley.edu/tos/dist-1.1.0/tools/windows/tinyos-cygwin-auto.zip">http://webs.cs.berkeley.edu/tos/dist-1.1.0/tools/windows/tinyos-cygwin-auto.zip </a> <br>Using winzip, unzip the archive and execute the setup.exe file. Whenasked to 'choose a download source', select 'Install from localdirectory'. When asked to select the root install directory, do notmodify the given root directory but do take note of the defaultdirectory because later you will need to reinstall TinyOS intothis directory (step 5). Take the default local package directory.Accept the defaults on 'Select Packages'.</li> <li>Using the Add/Remove Programs UI, run Installshield to completethe *un*install. Note that the setup wizard will launch black bashshells for each RPM that it uninstalls. These windows might displayan error at the top of the window -- this is normal.</li> <li>Completely remove the cygwin installation (<a href="#cygwin">seesteps above</a>)</li> <li>Run the 1.1.0 Installshield setup again to install; SPECIFYTHE SAME DIRECTORY as the initial, failed install. </li></ol></body></html>⌨️ 快捷键说明
