To install a package of the non-default architecture just specify that architecture on the command line: <span id="line-100" class="anchor"></span><span id="line-101" class="anchor"></span><span id="line-102" class="anchor"></span>

<pre><span id="line-1-8" class="anchor"></span>apt-get install package:architecture</pre>That package's dependencies will be installed automatically for the correct architectures (same-arch library deps, machine-arch for other deps) <span id="line-104" class="anchor"></span>e.g  <span id="linepre>apt-105" class="anchor">get install links:armhf</spanpre><span id="linepre>dpkg -106" class="anchor"></span><span id="linei package_version_architecture.debdpkg -107" class="anchor">r package:architecture</spanpre>

To install build-dependencies of a package before cross-building: <span id="line-118" class="anchor"></span><span id="line-119" class="anchor"></span><span id="line-120" class="anchor"></span>

<pre><span id="line-1-11" class="anchor"></span>apt-get build-dep -a </pre>This only works when all the 'tools' packages depended-on are marked <tt>Multi-Arch: foreign</tt>, any depended-on libraries which are also needed on the BUILD machine, and -dev packages which are needed for both HOST and BUILD architectures are made co-installable ('Multi-Arch: same' with arch-qualified paths), and any exceptions to the default rules are marked <tt>package:any</tt> or <tt>package:native</tt> in the package source. This process is ongoing. <span id="line-123" class="anchor"></span><span id="line-124" class="anchor"></span>

When it doesn't work you can often get the dependencies installed with a manual apt-get line: <span id="line-125" class="anchor"></span>e.g instead of <span id="line-126" class="anchor"></span><span id="line-127" class="anchor"></span>

<pre><span id="line-1-12" class="anchor"></span>apt-get build-dep -a armhf acl</pre>, do<span id="line-128" class="anchor"></span><span id="line-129" class="anchor"></span><span id="line-130" class="anchor"></span>

<pre><span id="line-1-13" class="anchor"></span>apt-get install autoconf automake debhelper gettext libtool libattr1-dev:armhf</pre>
