<p>Prerequisites:</p>
<ul>
<li><code>python3</code> (for: build) (but you can skip this dependency by editing <code>conf-home</code> in other ways)</li>
<li><code>gcc</code> (for: build)</li>
</ul>
<p>Make sure to <a href="test.html">test</a> the compiled code.</p>
<h3 id="scope">Installation scope</h3>
<p>The installation is of commands:
binaries
<code>cdbdump</code>, <code>cdbget</code>, <code>cdbmake</code>, <code>cdbstats</code>, <code>cdbtest</code>,
scripts
<code>cdbmake-12</code> and <code>cdbmake-sv</code>,
and the same for <code>cdb64</code>.</p>
<p>There is also a
<a href="cdb.html">C API</a>
for reading databases,
but the library per se is not installed:
applications instead integrate the relevant C files
(currently
<code>cdb.h</code>,
<code>cdb.c</code>,
<code>cdb_hash.c</code>,
<code>byte.h</code>,
<code>byte_copy.c</code>,
<code>byte_diff.c</code>,
<code>inbuf.h</code>,
<code>inbuf_unixread.c</code>,
<code>seek.h</code>,
<code>seek_set.c</code>,
<code>num.h</code>).</p>
<h3>For sysadmins</h3>
<p>To install in <code>/usr/local/bin</code>:</p>
<pre><code>make -j8 install
</code></pre>
<h3>For developers with an unprivileged account</h3>
<p>Typically you'll already have</p>
<pre><code>export PATH="$HOME/bin:$PATH"
</code></pre>
<p>in <code>$HOME/.profile</code>. To install in <code>$HOME/bin</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 binaries and scripts.</p>
<h3>More options</h3>
<p>You can edit the files <code>conf-cc</code> and <code>conf-ld</code>
to control the choices of compiler and linker.</p>
<p>For example,
<code>sed -i s/gcc/filcc/ conf-cc conf-ld</code>
switches from <code>gcc</code> to
<a href="https://fil-c.org/">Fil-C</a>.
Switching to Fil-C
is recommended for all applications
that (1) work with Fil-C and
(2) aren't a bottleneck for you.
This package works with Fil-C.</p><hr><font size=1><b>Version:</b>
