Re: [Machinekit] Machinekit not starting: seems to be attempting to start incorrect rtapi app

Can you try running the flavor binary in /usr/libexec Running flavor on its own should give the kernel flavour Also run flavor -m , flavor -b and flavor -d This seems similar to Simon Mali's problem when he upgraded, the kernel flavour was not being detected and a default of posix was being tried.

I've apparently successfully installed and started an RT-PREEMPT kernel (see ref 1), properly installed the appropriate machinekit packages (see ref2), and tried to start things up with various configurations. Ref 3 shows a representative error (through iterations I determined that just trying to run 'realtime' yields the same errors as starting the whole package, and errors out much quicker.) My interpretation of ref 3 is that it is trying to run rtapi_posix (not installed) instead of rt-preempt. As can be seen in ref 4 there is an executable for rtapi_app_rt-preempt but no rtapi_app_posix so it's no great surprise there is an error in ref 3. What simple thing am I missing here? I've been unsuccessful in finding a solution in this forum and on the machinekit website.  Ref 1 { brian@surely:/usr/libexec/linuxcnc⇒  uname -a Linux surely 4.1.19-rt22mah #1 SMP PREEMPT RT Tue Mar 15 09:12:20 CET 2016 i686 GNU/Linux } Ref 2 { brian@surely:/usr/libexec/linuxcnc⇒  apt list --installed | grep machine machinekit/stable,now 0.1.1489960089-1mk.travis.master.git7df8d183~1jessie i386 [installed,automatic] machinekit-dev/stable,now 0.1.1489960089-1mk.travis.master.git7df8d183~1jessie i386 [installed] machinekit-rt-preempt/stable,now 0.1.1489960089-1mk.travis.master.git7df8d183~1jessie i386 [installed] } Ref 3 {brian@surely:~⇒  sudo realtime start                                                                     Warning - /usr/libexec/linuxcnc/rtapi_app_posix not setuid 'sudo make setuid' missing? /usr/bin/realtime: line 111: test: =: unary operator expected /usr/bin/realtime: line 174:  4065 Segmentation fault      ${rtapi_msgd} --instance=$MK_INSTANCE $NAME_CMD --rtmsglevel=$DEBUG --usrmsglevel=$DEBUG --halsize=$HAL_SIZE $MSGD_OPTS rtapi_msgd startup failed - aborting /usr/bin/realtime: line 192: /usr/libexec/linuxcnc/rtapi_app_posix: No such file or directory rtapi_app startup failed - aborting halcmd: cant connect to rtapi_app: -1 (uri= uuid=a42c8c6b-4025-4f83-ba28-dad21114744a): rtapi_rpc(): reply timeout halcmd: the rtapi:0 RT demon is not running - please investigate /var/log/linuxcnc.log halcmd: the msgd:0 logger demon is not running - please investigate /var/log/linuxcnc.log } Ref 4 { brian@surely:~⇒  ls /usr/libexec/linuxcnc  -l                                                            total 200 -rwxr-xr-x 1 root root  14888 Mar 19 17:52 flavor -rwxr-xr-x 1 root root   5960 Mar 19 17:52 inivar -rwxr-xr-x 1 root root  14268 Mar 19 17:52 pci_read -rwxr-xr-x 1 root root  14288 Mar 19 17:52 pci_write -rwsr-xr-x 1 root root 101368 Mar 19 17:52 rtapi_app_rt-preempt -rwxr-xr-x 1 root root  43960 Mar 19 17:52 rtapi_msgd } -- website: http://www.machinekit.io blog: http://blog.machinekit.io github: https://github.com/machinekit --- You received this message because you are subscribed to the Google Groups "Machinekit" group.
