<application>libevent</application> is an asynchronous event notification
|
|
software library. The <application>libevent</application> API provides a
|
|
mechanism to execute a callback function when a specific event occurs on
|
|
a file descriptor or after a timeout has been reached. Furthermore,
|
|
<application>libevent</application> also supports callbacks due to
|
|
signals or regular timeouts.

First, fix an issue that prevents rpcgen_event.py from working:
|
|
</para>
|
|
|
|
<screen><userinput remap="pre">sed -i 's/python/&3/' event_rpcgen.py</userinput></screen>
|
|
|
|
<para>
|
|
Install <application>libevent</application> by running the following
|
|
commands:
|
|
</para>
|
|
|
|
<screen><userinput>./configure --prefix=/usr --disable-static &&
|
|
make</userinput></screen>
|
|
|
|
<para>
|
|
If you have <xref linkend="doxygen"/> installed and wish to build API
|
|
documentation, issue :
|
|
</para>
|
|
|
|
<screen remap="doc"><userinput>doxygen Doxyfile</userinput></screen>
|
|
|
|
<para>
|
|
To test the results, issue: <command>make verify</command>. Six tests in
|
|
every suite related to <filename>regress_ssl.c</filename> and
|
|
<filename>regress_http.c</filename> are known to fail due to
|
|
incompatibilities with OpenSSL-3.

</para>

|
|
</para>
|
|
|
|
<screen role="root"><userinput>make install</userinput></screen>
|
|
|
|
<para>
|
|
If you built the API documentation, install it by issuing the following
|
|
commands as the <systemitem class="username">root</systemitem> user:
|
|
</para>
|
|
|
|
<screen role="root"
|
