[etherlab-users] ethercat : modules_install error

[Christoph Schroeder]

Hi Roman,

the modules are installed into "/lib/modules/${version}". Your kernel doesn't match the configured kernel (4.4.0-21-generic) so all you might have to do is to call ./configure (with all options needed by your application) and make again.

The directory "/etc/sysconfig" is where the ethercat config is put on RedHat based Linux distributions. On Debian based distributions like Mint you may put it into "/etc/default" or just make a "/etc/sysconfig". If you don't put it into sysconfig you have to alter ETHERCAT_CONFIG in the init.d script.

Best Regards,
Christoph

Hello everybody!

I use Linux Mint 18 Cinnamon and want to install a module on my 4.4.0-53-generic x86_64 kernel.
I try to run Ethercat as discription of instalation in the script, for that I use the command $ sudo make modules_install and get the following error message:

~/ethercat-1.5.2 $ sudo make modules_install

Here are all programs / libraries, which I have additionally loaded and updated:

$ sudo apt-get install build-essential libssl-dev libelf-dev libqt4-dev libncurses-dev libncurses5-dev libqt4-dev g++ cpufrequtils libnuma-dev htop samba sysfsutils git rt-tests inxi numactl insserv bin86 kernel-package pkg-config linux-headers-$(uname -r) mercurial


Also I´ve made some changes in two files:

ethercat-1.5.2/devices/generic.c:

fixed
sock_create_kern(&init_net, PF_PACKET, SOCK_RAW, htons(ETH_P_ETHERCAT),
                              &dev->socket);
original Z215,SP.11
                               ret = sock_create_kern(PF_PACKET, SOCK_RAW, htons(ETH_P_ETHERCAT),
                              &dev->socket);


fixed
                               dev->netdev = alloc_netdev(sizeof(ec_gen_device_t *), &null, NET_NAME_UNKNOWN, ether_setup);
original Z152
                               dev->netdev = alloc_netdev(sizeof(ec_gen_device_t *), &null, ether_setup)


ethercat-1.5.2/master/ethernet.c

fixed
                               if (!(eoe->dev = alloc_netdev(sizeof(ec_eoe_t *), name, NET_NAME_UNKNOWN, ether_setup))) {
original Z151
                               if (!(eoe->dev = alloc_netdev(sizeof(ec_eoe_t *), name, ether_setup))) {


Also in my version the path /etc/sysconfig/ doesn´t exist. Which path I have to use after modules_install is working? I would be grateful for any help!

Roman
