this message is informational -- not an error that would cause termination >> Application initialization failed: no display name and no $DISPLAY >> environment variable >> Not starting new LinuxCNC This misleading message is more likely caused by existence of a 'leftover' LOCKFILE probably from an earlier failure of the buildbot instance. Note that the runtests scripts *unsets* the DISPLAY environmental variable: "# The linuxcnc starter script sometimes tries to display X windows if # DISPLAY is set. We never want that while running tests, so unset it. unset DISPLAY" Ref: https://github.com/LinuxCNC/linuxcnc/blob/2.8/scripts/runtests#L7 I made a test branch rebased to 2.8 at 69f7ce09b that rm'd the LOCKFiLE as a workaround: Ref: https://github.com/LinuxCNC/linuxcnc/commits/dgarr/tst28 https://github.com/LinuxCNC/linuxcnc/commit/80b413852a1d3de2d837d28d855de8f730cd83df This workaround lets a failing buildbot instance get a little further reporting: " !!! unexpected LOCKFILE at start of runtests !!! removing /tmp/linuxcnc.lock !!! Note: this debug does not solve problem of a leftover LOCKFILE Running test: /home/buildslave/emc2-buildbot/wheezy-i386/rip-wheezy-i386/build/tests/abort/feed-rate + rm -f sim.var + linuxcnc -r test.ini Machine configuration file is 'test.ini' Starting LinuxCNC... (time=1598926913.533681,pid=24099): Registering server on TCP port 5005. libnml/cms/tcp_srv.cc 280: bind error: 98 -- Address already in use libnml/cms/tcp_srv.cc 281: Server can not bind the connection socket on port 5005. libnml/rcs/rcs_exit.cc 96: Errors Reported!!! Press ^C to exit. " Ref: http://buildbot.linuxcnc.org/buildbot/builders/1400.rip-wheezy-i386/builds/5354/steps/runtests/logs/stdio The 'Address already in use' probably relates to an earlier problem and likely needs manual intervention or a reboot of the reporting buildbot instance(s). A reboot will (conventionally) rm the LOCKFILE in /tmp as well. -- Dewey Garrett _______________________________________________ Emc-developers mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-developers
