Hello,

Here is my cross-compile make command to build dbus-daemon util.

./configure  --host=mipsel-linux-gnu --disable-static --enable-shared
--prefix=/usr CC=/opt/toolchains/stbgcc-4.8-1.6/bin/mipsel-linux-gnu-gcc
LD=/opt/toolchains/stbgcc-4.8-1.6/bin/mipsel-linux-gnu-ld
--enable-tests=no && sudo make && sudo make install


After that I run "dbus-daemon --system &" as daemon. The system-config file
was attached.

However, when I run my application or 'dbus-monitor' util then I get bellow
error.


"Fail to connect to socket /usr/var/run/dbus/system_bus_socket: No such
file or directory".


Even I check in /tmp/dbus/ then I can see 'pid' & 'system_bus_socket' was
created there when running dbus-daemon.


It is a bit weird since I set local socket as
'<listen>unix:path=/tmp/dbus/system_bus_socket</listen>' in system.conf
file.

But this error still happen.


Could anyone help me to point out the root cause ?


Thanks,
