Log captured via 'bitbake -vv -D dbus  | tee -a dbus.build.log 2>&1'

Dbus recipe fails when systemd is enabled. In the dbus recipe (poky/meta/recipes-core/dbus/dbus_1.10.6.bb)(upstream poky), if systemd is enabled, then the do_install task will "cd" into the sysroot. Then at the end, the same directory gets deleted, then the CWD error pops up and things get worse and worse. Error appears when attempting to build Automotive Grade Linux  (http://docs.automotivelinux.org/docs/getting_started/en/dev/) for the Raspberry Pi 3b board (http://docs.automotivelinux.org/docs/getting_started/en/dev/reference/machines/raspberrypi.html).

To fix, must change:
125         cd ${D}${systemd_system_unitdir}/dbus.target.wants/                                                        
126         ln -fs ../dbus.socket ${D}${systemd_system_unitdir}/dbus.target.wants/dbus.socket
127         ln -fs ../dbus.socket ${D}${systemd_system_unitdir}/sockets.target.wants/dbus.socket
128         ln -fs ../dbus.service ${D}${systemd_system_unitdir}/multi-user.target.wants/dbus.service


To:
125         OLDPATH=`pwd`
126         cd ${D}${systemd_system_unitdir}/dbus.target.wants/
127         ln -fs ../dbus.socket ${D}${systemd_system_unitdir}/dbus.target.wants/dbus.socket
128         ln -fs ../dbus.socket ${D}${systemd_system_unitdir}/sockets.target.wants/dbus.socket
129         ln -fs ../dbus.service ${D}${systemd_system_unitdir}/multi-user.target.wants/dbus.services
130         cd $OLDPATH

Comment 1 Ross Burton 2017-01-27 20:17:54 UTC 
There's no need to do a cd at all if the ln calls use absolute paths for the link name, so the patch can just be to delete the cd.

Feel free to send a patch as you're in the perfect environment to test that it works.

Will do, gotta complete the build I'm on then I'll make a patch file

Patch that fixes stated bug

This is the promised patch. Build finished successfully (including the troublesome section in dbus) and generated a usable Automotive Grade Linux image for raspberry pi, which I have running on my local pi.

The comments form informs me not to submit patches here. Unfortunately, I'm not sure what mailing list to send this to. Can someone take a look at this?
Comment 4 Ross Burton 2017-02-06 16:43:47 UTC 
Patch looks good.  Patches for openembedded-core go to the openembedded-core@lists.openembedded.org mailing list: http://www.openembedded.org/wiki/How_to_submit_a_patch_to_OpenEmbedded
Comment 5 Ross Burton 2017-02-09 16:48:11 UTC 
Patch on the list.
Comment 6 Ross Burton 2017-02-21 17:14:58 UTC 
Fixed in oe-core 64d75438955c39e01187e897e9df47c93ac6c45a.
