<p>Prerequisites:</p>
<ul>
<li><code>python3</code> (for: build, test)</li>
<li><code>gcc</code> and/or <code>clang</code> (for: build)</li>
<li><code>valgrind</code> (for: build, test)</li>
<li><a href="https://cpucycles.cr.yp.to"><code>libcpucycles</code></a> (for: build, bench)</li>
<li><a href="https://randombytes.cr.yp.to"><code>librandombytes</code></a> (for: build, test, bench, run)</li>
</ul>
<p>Make sure to <a href="test.html">test</a> the compiled library.
The tests check for subtle security problems that can be created by compilers.
A compiled version of libmceliece is <strong>not supported</strong> unless it passes the full test suite.</p>
<h3>For sysadmins</h3>
<p>To install in <code>/usr/local/{include,lib,bin,man}</code>:</p>
<pre><code>./configure && make -j8 install
</code></pre>
<h3>For developers with an unprivileged account</h3>
<p>Typically you'll already have</p>
<pre><code>export LD_LIBRARY_PATH="$HOME/lib"
export LIBRARY_PATH="$HOME/lib"
export CPATH="$HOME/include"
export MANPATH="$HOME/man"
export PATH="$HOME/bin:$PATH"
</code></pre>
<p>in <code>$HOME/.profile</code>. To install in <code>$HOME/{include,lib,bin,man}</code>:</p>
<pre><code>./configure --prefix=$HOME && make -j8 install
</code></pre>
<h3>For distributors creating a package</h3>
<p>Run</p>
<pre><code>./configure --prefix=/usr && make -j8
</code></pre>
<p>and then follow your usual packaging procedures for the
<code>build/0/package</code> files:</p>
<pre><code>build/0/package/include/mceliece.h
build/0/package/lib/libmceliece*
build/0/package/bin/mceliece*
build/0/package/man/man3/*.3
build/0/package/man/man1/*.1
</code></pre>
<h3>More options, part 1: architectures</h3>
<p>You can run</p>
<pre><code>./configure --host=amd64
</code></pre>
<p>to override <code>./configure</code>'s guess of the architecture that it should
compile for.</p>
<p>Inside the <code>build</code> directory, <code>0</code> is symlinked to <code>amd64</code> for
<code>--host=amd64</code>. Running <code>make clean</code> removes <code>build/amd64</code>. Re-running
<code>./configure</code> automatically starts with <code>make clean</code>.</p>
<p>A subsequent <code>./configure --host=arm64</code> will create <code>build/arm64</code> and
symlink <code>0 -> arm64</code>, without touching an existing <code>build/amd64</code>. However,
cross-compilers aren't yet selected automatically.</p>
<h3>More options, part 2</h3>
<p>One further <code>./configure</code> option is supported for
<a href="internals.html">developers</a>:
<code>--no-trim</code>.</p>
<p>All <code>./configure</code> options not listed above are experimental and <strong>not supported</strong>.
Use them at your own risk.</p><hr><font size=1><b>Version:</b>
