Stuck with installation of Eathercat-Master

hello everyone

I am new in the world of linuxcnc , and I have a limited experience with linux too. I tried several different ways to install eathercat-master software, but all went in vain. I posted my problem here because it seems to me to be caused by my limited experience in installation these packages, not because the nature of ethercat itself.
I found different methods to install eathercat master:
1) wiki.linuxcnc.org/cgi-bin/wiki.pl?EtherCatDriver
in this link it mentions 2 methods:
the first method :
Installation

If you are using the current LinuxCNC Distribution (LCNC 2.6 Debian Wheezy based at time of writing) the installation is pretty simple:

create a file "/etc/apt/sources.list.d/linuxcnc-mds.list":

deb repo.modusoft.de/linuxcnc/wheezy ./

# sudo apt-get update
# sudo apt-get install linuxcnc-ethercat

the result that I get is that " repo.modusoft.de/linuxcnc/wheezy ./" no more exist and gives 502 error.

the second method is:

# git clone github.com/sittner/linuxcnc-ethercat.git linuxcnc-ethercat
# cd linuxcnc-ethercat
(these two lines work well)
and do a
# make

the result that I get when I do make: configure.mk:8: *** halcompile/comp executable not found or set. Stop.
make: *** [config.mk] Error 2

there is a not in the end of method 2 that I could not understand too:
You need etherlabmaster-dev (from the repos mentioned above) and linuxcnc-dev to be installed for this.


2) here another method github.com/sittner/ec-debianize
# ./configure -a
# cd ..
# dpkg-checkbuilddeps
# dpkg-buildpackage


the result that I get: the terminal refuses the -a with configure, and when I remove -a and I the first line without it, I get this error in the end of the command output :
configure: error: Failed to find Linux sources. Use --with-linux-dir!


I do not know if it was better to publish this topic in hal component forum, but it seems to me that these erronous results are caused by missing commands/packages that I am not aware about.

thanks

Note: I forgot to mention that my linuxcnc is based of RT-Preemption patch.

I am not sure, but i think you also need to copy the linuxcnc git master to your computer, so check the wiki and find the "run in place" how to, or how to pull a git version of linuxcnc.

There are two different things that need to be installed. The IgH EtherCAT Master and sittner's EtherCAT HAL Driver.

IgH Etherlab EtherCAT Master
1. Download Etherlab Ethercat from the website www.etherlab.org/en/ethercat/
2. Extract the tarball 3. Run the configuration tool and build (omit the --enable-r8169 if not using the Realtek 8169 driver) 4. Become root 5. Install the software 6. Install the system service 7. Check HWaddr of network device 8. Edit EtherCAT master config to use the MAC address of your chosen network device 9. Add your MAC address 10. Edit the DEVICE_MODULES line, adding the r8169 device (again, omit if not using the Realtek 8169 driver) 11. Update Configuration 12. Give normal users read access to EtherCAT character devices 13. Make the master executable 14. Start the master service 15. Operation can be observed by viewing the Syslog messages
LinuxCNC EtherCAT HAL Driver
1. Download the latest version from github 2. Install etherlabmaster-dev 3. Open the git directory 4. Build 5. Copy the built binary to the ethercat directory

Hello Everyone,

I successfully installed all to point 4 (build hal driver)
Terminal gives me the following text:

Any ideas what the problem is?

These lines stick out as some likely suspects.
Make sure your system time is correct (run date in a terminal and see what it outputs)
Check the date/time on the files
You might be able to get around any time discrepancies by updating the timestamps of all the files to match your system time

The current git revision of linuxcnc-ethercat comes with one file mis-named. configure.mk should be config.mk
