    <title>Installation of Mercurial</title>

    <para>Build <application>Mercurial</application> by issuing the following
    command:</para>

<screen><userinput>make build</userinput></screen>

    <para>To build the documentation (requires
    <application>Docutils</application>), issue:</para>

<screen><userinput>make doc</userinput></screen>

    <para>Running the test suite is optional. Failure of test-patchbomb is
    expected with <application>Python-2.7.x</application> (x &gt; 7). To test
    the results in the subdiretory
    <filename class="directory">tests/tmp</filename>,
    skipping the failing test, issue:</para>

<screen><userinput>cat &gt; tests/blacklists/test-failed &lt;&lt; "EOF"
<literal># Failure with Python-2.7.8
  test-patchbomb.t</literal>
EOF
rm -rf tests/tmp &amp;&amp;
TESTFLAGS="--tmpdir tmp --blacklist blacklists/test-failed" \
make check</userinput></screen>

    <para>More failing tests might be added to that file, if necessary. Tests
    may be run in parallel, just add <quote>-j$(getconf
    _NPROCESSORS_ONLN)</quote> to TESTFLAGS. In order to investigate a
    particular apparently failing test, e.g <quote>test-parse-date.t</quote>,
    issue the following commands (notice that omitting <option>--debug</option>
    sometimes modifies the result):</para>

<screen><userinput>pushd tests &amp;&amp;
rm -rf tmp  &amp;&amp;
./run-tests.py --debug --tmpdir tmp test-parse-date.t &amp;&amp;
popd</userinput></screen>

    <para>Install <application>Mercurial</application> by running
    the following command (as <systemitem class="username">root</systemitem>):</para>

<screen role="root"><userinput>make PREFIX=/usr install-bin</userinput></screen>

    <para>If you built the documentation, install it by running
    the following command (as <systemitem class="username">root</systemitem>):</para>

<screen role="root"><userinput>make PREFIX=/usr install-doc</userinput></screen>

    <para>After installed, two very quick and simple tests should run correctly.
    First one needs some configuration:</para>

<screen><userinput>cat &gt;&gt; ~/.hgrc &lt;&lt; "EOF"
<literal>[ui]
username = &lt;user_name&gt; &lt;your@mail&gt;</literal>
EOF</userinput></screen>

    <para>where you must replace &lt;user_name&gt; and &lt;your@mail&gt; (mail
    is optional and can be omitted). With the user identity defined, run
    <command>hg debuginstall</command> and several lines will be displayed, 
    the last one reading "no problems detected". Another quick and simple test
    is just <command>hg</command>, which should output basic commands that can
    be used with <command>hg</command>.</para>
