The dbus tests cannot be run until after <xref linkend="dbus-glib"/>
|
|
has been installed. They must be run as an unprivileged user from a
|
|
local session. Tests fail through ssh. If you want to run only the unit
|
|
tests, replace, below, <parameter>--enable-tests</parameter> by
|
|
<parameter>--enable-embedded-tests</parameter>, otherwise,
|
|
<xref linkend="dbus-python"/> has to be installed, before.
|
|
The tests require passing additional parameters to
|
|
<command>configure</command> and exposing additional functionality in
|
|
the binaries. These interfaces are not intended to be used in a
|
|
production build of <application>D-Bus</application>. If you would
|
|
like to run the tests, issue the following commands:
|
|
</para>
|
|
|
|
<screen><userinput>make distclean &&
|

<para>

If <command>run-test.sh</command> fails, it can be disabled with the

following sed, before running the commands for the tests:

<screen><userinput>sed -i -e 's:run-test.sh:$(NULL):g' test/name-test/Makefile.in</userinput></screen>

<note><para>
|
|
There has been a report that the tests may fail if running
|
|
inside a Midnight Commander shell.
|
|
You may get out-of-memory error messages when running the tests.
|
|
These are normal and can be safely ignored.

There are many methods you can use to start a
|
|
session daemon using the <command>dbus-launch</command> command. Review
|
|
the <command>dbus-launch</command> man page for details about the
|
|
available parameters and options. Here are some suggestions and
|
|
examples:

If you use <command>xdm</command> or some other display manager

that calls the <filename>~/.xsession</filename> file, you can add
|
|
<command>dbus-launch</command> to the line in your
|
|
<filename>~/.xsession</filename> file that starts your graphical
|
|
desktop environment. The syntax would be similar to the example in

the <filename>~/.xinitrc</filename> file.

The examples shown previously use
|
|
<command>dbus-launch</command> to specify a program to be run. This
|
|
has the benefit (when also using the
|
|
<parameter>--exit-with-session</parameter> parameter) of stopping the
|
|
session daemon when the specified program is stopped. You can also
|
|
start the session daemon in your system or personal startup scripts
|
|
by adding the following lines:
|
|
</para>
|
|
|
|
<screen><userinput><literal># Start the D-Bus session daemon
|
|
eval `dbus-launch`
|
|
export DBUS_SESSION_BUS_ADDRESS</literal></userinput></screen>
|
|
|
|
<para>
|
|
This method will not stop the session daemon when you exit
|
|
your shell, therefore you should add the following line to your
|
|
<filename>~/.bash_logout</filename> file:
|
|
</para>
|
|

<screen><userinput><literal># Kill the D-Bus session daemon
