Replied by bkt on topic Beckhoff ethercat 64 with bit linuxcnc, How to install.

@ tady Ok I see and understand ...

@ grotius for first thing and for convenience I am used to creating the /linuxcnc-dev folders in /myuser/home/linuxcnc-dev and never in /git/linuxcnc-dev (attention I always put absolute paths).

For ec-debianize & linuxcnc-ethercat is this correct? so can I use the following installation folders?

1- /myUser/home/linuxcnc-dev
2- /myUser/home/ec-debianizer
3- /myUser/home/linuxcnc-ethercat

This is fine? Or can it give problems because of missing root privileges?

if this is fine, can i also not run git and download and extract the single zip files is it correct? I refer to the following:

1- linuxcnc-2.8.zip
2- ec-debianizer-master.zip
3- linuxcnc-ethercat-master.zip

can I use this method or do I lose privileges on the street?

Actually i try on linuxcnc-stretch-uspace-amd64-r13.iso .... but I run into some small obstacles because I am not abiautato debian I think. After these that kernel is too outdated for my pourpose (not possible install some quick library for QT5.12 for example), so after these I would try with less old kernel ....

:silly: SUCCESS :blush:

so in the end it was just a problem of permissions and folders .... this is what I did to solve .... attention I only use absolute paths to not confuse anyone:

for first, I use ubuntu 18.04 and linux 4.18.9-rt9 64bit ... for install kernel and pach you can use google and/or search button here on forum .... there are many howto about ... when your rt-preempt SO is ready you can go here:

Code:

  https://github.com/LinuxCNC/linuxcnc/tree/2.8 --> download .zip file
  https://github.com/sittner/linuxcnc-ethercat --> download .zip file
  https://github.com/sittner/ec-debianize --> download .zip file

after these go to:

Code:

  /home/yourUser/Downloads/ec-debianize-master.zip ---> right click ---> extract here ----> right click ---> rename ---> "ec-debianize"

  /home/yourUser/Downloads/linuxcnc-ethercat-master.zip ---> right click ---> extract here ----> right click ---> rename ---> "linuxcnc-ethercat"

  /home/yourUser/Downloads/linuxcnc-2.8.zip ---> right click ---> extract here ----> right click ---> rename ---> "linuxcnc-dev"

move /home/yourUser/Downloads/ec-debianize and /home/yourUser/Downloads/linuxcnc-ethercat folder inside /home/yourUser/Downloads/linuxcnc-dev ... after these move /home/yourUser/Downloads/linuxcnc-dev on your home dir (/home/yourUser/linuxcnc-dev)

in these ways you obtain:

Code:

  /home/yourUser/linuxcnc-dev
  /home/yourUser/linuxcnc-dev/ec-debianize
  /home/yourUser/linuxcnc-dev/linuxcnc-ethercat

Now you can install linuxcnc rip install in the usual manner using teminal emulator (or other one):

Code:

  cd /home/yourUser/linuxcnc-dev/debian
  ./configure uspace noauto
  cd ..
  dpkg-checkbuilddeps (install required packages showed after command dpkg-checkbuilddeps then comeback)
  cd src
  ./autogen.sh
  ./configure --with-realtime=uspace
  make -j4 (if you have 4 core cpu)
  sudo make setuid
  cd ..
  . ./scripts/rip-environment

now rip-install is complete NO EXIT FORM TERMINAL and linuxcnc folder!!
We can use Gitorius howto for run ec-debianize:

Code:

  (in a new one terminal)sudo apt-get install quilt (dependency for ec-debianize) + sudo apt-get install mercurial 

  cd /home/yourUser/ ---> right click "create new empty document" ----> using gedit write inside it these:

  [extensions]
  mq = qpush
  mq = 

  now "save as" ---> name these new documents '.hgrc' ----> save again and close

  (now we can close the new terminal and return to old one with  . ./scripts/rip-environment instance)

  cd /home/yourUser/linuxcnc-dev/ec-debianize =>sudo ./get_source.sh 

  cd /home/yourUser/linuxcnc-dev/ec-debianize/etherlabmaster/ => sudo dpkg-buildpackage (dpkg-checkbuilddeps optional)
  (the output error "failed to sign .dsc file is no issue)

  cd ..

  cd /home/yourUser/linuxcnc-dev/ec-debianize/ => sudo dpkg -i etherlabmaster_1.5.2+20190904hg33b922p8ea394-1_amd64.deb

  cd /home/yourUser/linuxcnc-dev/ec-debianize/ => sudo dpkg -i etherlabmaster-dev_1.5.2+20190904hg33b922p8ea394-1_amd64.deb

now we can set ethercat master device and correct a file inside linuxcnc-ethercat
... open new terminal and CLOSE THE OLD ONE
NOTE we work with . ./scripts/rip-environment istance open on linuxcnc-dev folder all the time.

Code:

   Find your mac adres : $ ip link show (output = link/ether ....) and copy it on clipboard

   sudo gedit /etc/default/ethercat ---> find and type in row  MASTER0_DEVICE="lo:ve:me:te:nd:er" (your mac adres my dear ... original joke of gitorius)
   ---> find and type in row DEVICE_MODULES="generic"
   ---> save and exit from gedit
   sudo update-ethercat-config

   cd gedit /home/yourUser/linuxcnc-dev/linuxcnc-ethercat/src/lcec_main.c (add here [#include "rtapi_mutex.h"] below [#include "rtapi_app.h"])
  ----> save and close gedit
  ----> cd
  ----> reboot

when your pc become ready ... open a new terminal windows:
Now we can compile linuxcnc-ethercat:

Code:

  cd /home/yourUser/linuxcnc-dev --->  . ./scripts/rip-environment
  cd /home/yourUser/linuxcnc-dev/linuxcnc-ethercat ----> make

After these we have installd all linuxcnc-ethercat glue .... for sure we need to copy lcec_main.so and conf ... but for these origina how to of Gitorius is a real valid help. I rewrite it here out of comedy:

4. To start linuxcnc with ethercat, start linuxcnc with simple axis gui.
copy lcec_conf ==> ../linuxcnc-ethercat/src/lcec_conf ==> to your linuxcnc sim map (copy it where your ini files is)
copy lcec_so ==> ../linuxcnc-ethercat/src/lcec.so ==> to your home/.../linuxcnc/rtlib/ (this is only for linuxcnc_dev users)
copy and edit the ethercat_config.xml from the linuxcnc-ethercat example directory and copy it where your ini file is.
In your ini file add "HALFILE = postgui.hal"
make a postgui.hal file include :
loadusr -W lcec_conf ethercat-conf.xml
#loadrt lcec
#addf lcec.read-all servo-thread
#addf lcec.write-all servo-thread
First check if lcec_conf will load, open your halmeter.
When you see the Lcec section, uncheck the # sign's in the postgui.hal file.

today my EK1100 has arrived ... so I can do live tests. If there are surprises I will write it here .... but I think I will find only the usual skirmishes.

After this step I will try to do the same with linuxcnc-2.9 (master) let's see if it works ... if it goes I'll bring it back here.

Replied by bkt on topic Beckhoff ethercat 64 with bit linuxcnc, How to install.

yesterday I have a trouble with my installation .... I share my teminal output today:

Warning: Spoiler!

after some reading of similar problems in the past to users and developers and after checking with ldd the various folder paths and some installation files such as ethercat.spec and others ... I came to the conclusion that ec-debianizer was not designed to rip-install ... so that the necessary shared libraries do not match the required system folders. However ethercat master works and communicates with EK1100 and EL1008 and EL2008 .... only if realtime configuration is called (rt-preempt and certainly not rtai) it will not be able to start the program as lcec.so will not be able to connect to the required libraries.

So for now is not possible use ec-debianize for an linuxcnc rip-install with etherecat communication

I work for solve these problem but need some help because never touch makefile etc etc .... for shure the problem is old see here github.com/sittner/linuxcnc-ethercat/issues/61 .... but find solution for a rip-instal for now .... I don't even know if it's interesting .... in fact, the rip-installs are tests ... after your tests you should install .... but my tests last for months and sometimes I have up to 8 rip-installs on the same PC. .. (incidentally this pc on which I tried ethercat is "virgin").

Hi @btk,

I was about to suggest that the RIP might be the issue, that is why on my tutorial I show the debian machine installation. ec-debianize would run independently (RIP or machine install) but then the linuxcnc-ethercat would still require to use your method for a RIP install.

Good that you identified the issue.

thanks @Nico2017 ... can you print from your debian install what is the output of: ldd /rtlib/lcec.so ??

In these manner I can see the difference from mine.

thanks again
