Re: [Machinekit] Re: Debian package related problem

OK, a one off Quick Guide to install on i386 It really is not difficult, so long as you have some idea what you are trying to do. Install Debian Stretch i386 net install distro from USB or CD During installation: Create root and user with same password (so you don't forget it) Under software selections: Select LXDE desktop and ssh server, remove print server Near the end, install grub to MBR. Reboot, login as normal user and open menu (Ctrl Esc) > System > Root_Terminal (# indicates the root command line prompt) # apt update (should be fully up to date if using net install) # apt install firmware-linux-non-free firmware-realtek (if you have a RTL NIC) dirmngr #apt install linux-image-rt-686-pae Reboot and sign in as your normal user From root terminal (Ctrl Esc > System > Root_Terminal) # uname -a check you have booted the rt kernel # apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 43DDF224 # echo 'deb http://deb.machinekit.io/debian stretch main' > /etc/apt/sources.list.d/machinekit.list # apt update # apt install machinekit machinekit-rt-preempt # leafpad /etc/ssh/sshd.conf & Then uncomment the line beginning '#AllowRootLogin....' and edit so it reads ' AllowRootLogin yes' save file and close leafpad # service sshd reload Now you will be able to ssh into the machine with root permissions for maintenance Now close root terminal and (Ctrl Esc > System > LXDE_Terminal) for user terminal Alt Spacebar X - to maximise # machinekit Then you are running, select the axis sim to test. >> Start controlling things like LinuxCNC never could. I do have some concerns as to what you think you can do on an i386 with Machinekit, that you can't on linuxcnc. You do realise that a rt-preempt kernel will probably not give good enough latency to run from a parport? You need a rtai kernel for that and Machinekit does not support rtai any more. The things it can control that linuxcnc can't, are largely based on various armhf boards and soc_fpga boards etc. not PCs regards On 27/11/18 19:13, cncbuilder...@gmail.com wrote: Thanks for the suggestions. I have no idea how to use them. This what I thought was going to happen(a week ago). Install debian stretch. install Machinekit rt-reempt for stretch. Start controlling things like LinuxCNC never could. If you can show me how to get this going. I'm sure others will find it help full. Maybe a step by step guide for Dummies.   I want this to work...

As a result it tries to find the posix binaries and fails Warning - /usr/libexec/linuxcnc/rtapi_app_posix not setuid (That error is a bit misleading, because the binary could not be opened it assumes things, does not consider that it might not exist!) So, as per the documentation http://www.machinekit.io/docs/getting-started/install-rt-kernel-i386/ install a rt-preempt kernel and BOOT THAT. If you already have and are just letting the system boot unwatched, it is obviously defaulting to posix, so you need to manually select the rt kernel or change the boot order in /boot/grub/grub.cfg On 27/11/18 09:10, cncbui...@gmail.com wrote:    New download/install debian 9.6.0 machinekit failed to run. See files attached. I will do the same for the amd64 rt-reempt install. If there is anything else you would like include let me know. I will keep this P4 on the bench for testing. I hope you find this helpful.

(what exactly can build and package for all architectures without errors, but cause failure when running on i386 only, remains to be seen!) A local package build from this tests OK in the i386 VM, so hopefully cured. The repo is rebuilding packages and they will be available in a couple of hours. I will update when they are in the repo and can be pulled for testing. On 26/11/18 13:01, schoo...@gmail.com wrote: I have now created a Debian Stretch i386 VM and installed machinekit dependencies.

I don't have any i386 computers any more and there is no error on amd64. Is Machinekit for programmers only?
