Beckhoff ethercat 64 with bit linuxcnc, How to install.

Hi @bkt
sorry, I guess I misread your problem.

Greeting

@chimeno ... no worry for the work you have done on ethercat theme here on the forum you can allow yourself many other mistakes without anyone having anything to complain about

Any how only chance is try to install Lcnc 2.8 ..... but we need to use joint/axis trick (angular or world coordinates on ngc file) provided by dgarret .... on 2.9 works ok on real machine ....

about halcopile not find .... I've not a solution now.

bkt

now I have an other questions ..... If install more than one Lcnc-dev versions on home folder ..... linuxcnc-ethercat-master can see the right one?? How??

I try to understand snitter code and where is call halcopile comp, but not see the call .... i think is only a problem of wrong path on 2.9 lcnc rt-preempt versions ... so I try to find the problem and fix it .....

Now for sure there are a problem. I try with these installation:

1. Remove previous Lcnc istallation
   Code:

   apt-get purge linuxcnc-doc-en linuxcnc-uspace-dev linuxcnc-uspace
2. Setup LinuxCNC 2.8 (download zip file from github selecting 2.8 version)
   Code:

   cd linuxcnc (renamed from linuxcnc2.8 into linuxcnc after extraction)/debian ./configure uspace cd .. cd src make ./autogen.sh ./configure --with-realtime=uspace make -j4 sudo make setuid
3. Setup "ec-debianize"
   Code:

   git clone https://github.com/sittner/ec-debianize ec-debianize cd /ec-debianize ./get_source.sh cd etherlabmaster dpkg-buildpackage (the output error "failed to sign .dsc file" is no issue) sudo dpkg -i /git/ec-debianize/etherlabmaster_1.5.2+20190904hg33b922p8ea394-1_amd64.deb (in my case) sudo dpkg -i /git/ec-debianize/etherlabmaster-dev_1.5.2+20190904hgp8ea394-1_amd64.deb (in my case) gedit /etc/default/ethercat (change mac-address [MASTER0_DEVICE=""] e.g. [MASTER0_DEVICE="15:27:33:48:55:66"]) gedit /etc/default/ethercat (change [DEVICE_MODULES=""] to [DEVICE_MODULES="generic"]) sudo update-ethercat-config usermod -a -G ethercat demo (my user) reboot
4. Setup "LinuxCNC-Ethercat"
   Code:

   git clone http://github.com/sittner/linuxcnc-ethercat.git linuxcnc-ethercat" gedit /git/linuxcnc-ethercat/src/lcec_main.c (add here [#include "rtapi_mutex.h"] below [#include "rtapi_app.h"]) cd /linuxcnc-ethercat make -j4 ----> error
5. Code:

   demo@demo:~/linuxcnc-ethercat$ make configure.mk:8: *** halcompile/comp executable not found or set. Stop. Makefile:17: recipe for target 'config.mk' failed make: *** [config.mk] Error 2

so nothing change from 2.9 Lcnc versions .... same problem ... where do I check to solve?

If you have some time left,

Soon i will do a new Ethercat installation to trigger your problem. Will let you know what can be your problem.

Ok thanks ... today i try to install the iso you have posted on first page of these thread .... in these way I hope I can start .... after these we can verify, with some your help, the differences between installation on debian 9 and ubuntu18.04/mint19 (that is the same SO with different WM and less bloatware on mint side, more or less .... but normally I start from minimal installation on ubuntu .... ).

Thanks for your help test ..... to date I have not seen what happened .... but I think it's just a problem of folder paths or rt-preemt patch version. If I knew the way linuxcnc-ethercat builds the paths and what it expects to find in the various folders, I probably would have already solved ... but this takes time which I don't know where to go.

Hey guys.

Can anyone tell me if someone installed this on a PI?

I am trying to build this package but after running
i get ....
Any ideas? probably the kernel is not supported?

Huh i just noticed that kernel versions do not match

and where did you find the news? I'm using the 4.18 kernel on mint .... and I'm having problems ...
