菜鸟笔记--IGH ethercat master在linux4.x环境下的编译安装

在etherlab官网上的ethercat IGH协议最高版本只到1.5.2，并且只支持linux2.x，3.x内核。对于现在普遍的ubuntu 16.4以上以及debian9以上的Linux发行版来说，都是linux4.x内核，网上的朋友如果参照几年前的帖子进行安装的话，在编译时会出现一系列棘手的BUG，导致走上排解BUG的不归路。

首先，在sourceforge上下载IGH stable-1.5版本，这个是支持linux4.x内核的。附上网址。
https://sourceforge.net/p/etherlabmaster/code/ci/stable-1.5/tree/
点击DownloadSnapshot进行压缩包下载
重命名为简短一点的名字 etherlab-stable1.5.zip
然后按照以下步骤配置，编译，安装即可

1、首先下载所需要的依赖

sudo apt install autoconf automake libtool net-tools
sudo apt-get install linux-headers-$(uname -r)

2、进行编译安装

unzip etherlab-stable1.5.zip
cd ~/etherlab-stable1.5      //注：这个文件夹为解压后重命名的文件夹，原来的名字太长不好记。
./bootstrap
./configure --enable-cycles --enable-hrtimer --enable-8139too=no
make all modules
sudo make modules_install install
sudo depmod
sudo ln -fs /usr/local/etc/init.d/ethercat /etc/init.d/
sudo mkdir /etc/sysconfig
sudo ln -fs /usr/local/etc/sysconfig/ethercat /etc/sysconfig/
sudo -i
echo KERNEL==\"EtherCAT[0-9]*\", MODE=\"0664\" > /etc/udev/rules.d/99-EtherCAT.rules

注意：与1.5.2版本不同，stable-1.5版本已将安装目录/opt/etherlab改为/usr/local

3、进行网络配置

edit /etc/sysconfig/ethercat
MASTER0_DEVICE=”00:0c:29:b4:aa:66”      //注：此为ifconfig命令显示的网卡地址，安装时应该为自己的
DEVICE_MODULES=”generic”

4、启动测试
