ERROR: dbus: cannot claim org.freedesktop.miracle.wifi bus-name: -13

[BSoDium]

Hello, I have followed the documentation thoroughly, and run the installation process, stopped the wpa_supplicant service etc. Still when I run miracle-wifid I get this error:

[11/06/22 - 03:56:45.006.458] INFO: miracle-wifid - revision 1.0 Nov  1 2022 03:23:07
[11/06/22 - 03:56:45.006.459] ERROR: dbus: cannot claim org.freedesktop.miracle.wifi bus-name: -13 (manager_dbus_connect() in wifid-dbus.c:943)
[11/06/22 - 03:56:45.006.460] DEBUG: exiting.. (main() in wifid.c:643)

I am running Debian bullseye, and these are the outputs of

$ ./res/test-hardware-capabilities.sh
wlp2s0 supports P2P

and

$ ./res/test-viewer.sh
testing plugins required:

test udpsrc... (passed)
test rtpjitterbuffer... (passed)
test rtpmp2tdepay... (passed)
test tsdemux... (passed)
test h264parse... (passed)
test avdec_h264... (passed)
test autovideosink... (passed)

everything installed

Any clues on why this could be happening?

Update: I now have a compilation error when running make:

/home/bsodium/Apps/miraclecast/build/src/shared/../../../src/shared/shl_log.c:160: undefined reference to `lrint'
collect2: error: ld returned 1 exit status
make[3]: *** [Makefile:442: miracle-wifid] Error 1
make[3]: Leaving directory '/home/bsodium/Apps/miraclecast/build/src/wifi'

make[1]: *** [Makefile:422: all-recursive] Error 1
make[1]: Leaving directory '/home/bsodium/Apps/miraclecast/build'
make: *** [Makefile:354: all] Error 2

Any ideas on what dependency I might be missing here?

[albfan]

after first install probably need to reload dbus systemctl daemon-reload or restarts could work.

lrint comes from math.h. Usually that is glibc but depends on your system

[BSoDium]

This doesn't seem to solve it:

$ sudo systemctl stop NetworkManager.service && sudo systemctl stop wpa_supplicant.service
$ sudo systemctl daemon-reload
$ sudo miracle-wifid 
ERROR: dbus: cannot claim org.freedesktop.miracle.wifi bus-name: -13 (manager_dbus_connect() in ../../../src/wifi/wifid-dbus.c:943)

I'm really out of ideas here, restarting doesn't work either.

[albfan]

That error means dbus is not corrctly configured.

What is your OS and which buildsystem did you use?

[BSoDium]

I am running Debian 11 buster, and used autotools since cmake did not seem to work (missing dependencies mentioned above). I can still try I get cmake to work if you think this is necessary.

[albfan]

13 means permission error. So dbus cannot claim that name

All buildsystem should work, but you need to notice some quirks depending on buildsystem

https://www.gnu.org/prep/standards/html_node/Directory-Variables.html

autotools configure step needs to redefine sysconfdir as it will use $prefix/etc and dbus should go into: /etc

res/Makefile.am dbuspolicydir=$(sysconfdir)/dbus-1/system.d

this is output in autogen.sh step, but maybe you miss it

----------------------------------------------------------------
Initialized build system. For a common configuration please run:
----------------------------------------------------------------

./configure CFLAGS='-g -O0 -ftrapv' --sysconfdir=/etc --localstatedir=/var --libdir=/usr/lib64 

still you can see that on configure output:

configure: Build configuration:
       prefix: /usr/local
       exec-prefix: ${prefix}
       bindir: ${exec_prefix}/bin
       libdir: ${exec_prefix}/lib
       includedir: ${prefix}/include
       sysconfdir: ${prefix}/etc
       ip-binary: /bin/ip

if you have:

/usr/local/etc/dbus-1/system.d/org.freedesktop.miracle.conf

or

/usr/etc/dbus-1/system.d/org.freedesktop.miracle.conf

that is not gonna work it should be:

/etc/dbus-1/system.d/org.freedesktop.miracle.conf

then

sudo systemctl daemon-reload

should work

Please confirm so we can add this to Wiki FAQ, is a common issue if you look at pass issues, and would be great to put that on wiki

[albfan]

This was already mentioned in Wifi FAQ. https://github.com/albfan/miraclecast/wiki/FAQ#install-dbus-policy

Not sure if document buildsystem quirks is a good or bad idea

Hi @BSoDium

My Raspbian OS:

pi@raspberrypi:/home/pi/miraclecast/build $ uname -a Linux raspberrypi 5.10.103-v7+ #1529 SMP Tue Mar 8 12:21:37 GMT 2022 armv7l GNU/Linux

pi@raspberrypi:/home/pi/miraclecast/build $ lsb_release -a No LSB modules are available. Distributor ID: Raspbian Description: Raspbian GNU/Linux 10 (buster) Release: 10 Codename: buster

And I have same problem when I running make:

make[3]: Entering directory '/home/pi/miraclecast/build/src/wifi' CCLD miracle-wifid /usr/bin/ld: ../shared/.libs/libmiracle-shared.a(shl_log.o): in functionlog__submit': /home/pi/miraclecast/build/src/shared/../../../src/shared/shl_log.c:160: undefined reference to lrint' collect2: error: ld returned 1 exit status make[3]: *** [Makefile:442: miracle-wifid] Error 1 make[3]: Leaving directory '/home/pi/miraclecast/build/src/wifi' make[2]: *** [Makefile:538: all-recursive] Error 1 make[2]: Leaving directory '/home/pi/miraclecast/build/src' make[1]: *** [Makefile:420: all-recursive] Error 1 make[1]: Leaving directory '/home/pi/miraclecast/build' make: *** [Makefile:352: all] Error 2

Did you solve this problem?

Hi @albfan

After search the key word in this repository, I got some info you mention before such as #458

"yes, I think that is usually glibc devel package" Could you explain more??

Because I already install reuirements lib sudo apt-get install gstreamer1.0-tools libglib2.0-0 libglib2.0-dev libreadline-dev libperl-dev autoconf automake libsystemd-dev libudev-dev libtool but it still can't make

Thanks

[albfan]

@YuanPeir-Chen I think you can try suggestion on https://github.com/albfan/miraclecast/issues/464

If reporter is able to submit a PR it should be fixed on master after merge.

[YuanPeir-Chen]

Hi @albfan

Thanks for quick reply.

Unfortunately, after try suggestion on #464 , it's also not work for using "autotools" and output is same as above

/home/pi/miraclecast/build/src/shared/../../../src/shared/shl_log.c:160: undefined reference to lrint' collect2: error: ld

Alternative build for cmake on latest commit from master, it's work for me, I can successfully make and install, but have another Error when I am testing

ERROR: supplicant: HUP on supplicant socket of wlan0

I will create another issue for ask

thanks.
