<p>The basic manifest for 1.6 defines which projects are
needed to do a generic build for the emulator or for unlocked Dream devices
(e.g. the Android Dev Phone 1). You need to have an appropriate device running
a matching official image.</p>
<p>To build donut for dream (your
device needs to be an ADP1 running an official 1.6 system):</p>
<ol>
<li>
<p>Follow the <a href="downloading.html">normal steps</a> to setup repo and check out the sources.</p>
</li>
<li>
<p>At the root of your source tree, run <code>. build/envsetup.sh</code> like you normally would for an emulator build.</p>
</li>
<li>
<p>Run <code>make adb</code> if you don't already have adb in your path.</p>
</li>
<li>
<p>run <code>adb root</code>.</p>
</li>
<li>
<p>in <code>vendor/htc/dream-open/</code> there is a script called "extract-files.sh" that must be run (from that directory) to extract some proprietary binaries from your device (*). You only need to do this once.</p>
</li>
<li>
<p>run <code>lunch aosp_dream_us-eng</code> to specifically configure the build system for dream (the default is the equivalent of "lunch generic-eng", which doesn't contain dream-specific files).</p>
</li>
<li>
<p>run make from the top of the source tree.</p>
</li>
<li>
<p>from this point, the fastboot tool (which is put automatically in your path) can be used to flash a device: boot the device into the bootloader by holding the back key while pressing the power key, and run <code>fastboot -w flashall</code>.</p>
</li>
</ol>
<p>Note: these instructions work for the sapphire (ADP2) build target, as
well. Simply replace "dream" with "sapphire" above.</p>
