<h4 id="description">Description</h4>
<p>Compiles, links, and builds an ELF binary for the target named &lt;target-name&gt;. It builds an ELF file for the application specified by the <code>app</code> variable for the <code>target-name</code> target. The image can be loaded and run on the hardware specified by the <code>bsp</code> variable for the target. The command creates the 'bin/' directory under the project's base directory (that the <code>newt new</code> command created) and stores the executable in the 'bin/targets/&lt;target-name&gt;/app/apps/&lt;app-name&gt;' directory. A <code>manifest.json</code> build manifest file is also generated in the same directory. This build manifest contains information such as build time, version, image name, a hash to identify the image, packages actually used to create the build, and the target for which the image is built.</p>
<p>You can specify a list of target names, separated by a space, to build multiple targets. </p>
