igh主站搭建过程(e1000e 网卡/ generic网卡）

1、下载igh源码
gary@jxes:~$ git clone https://gitlab.com/etherlab.org/ethercat.git
2、配置（可参考官方文档）
gary@jxes:~/Xenomai/xenomai-v3.2.1$ sudo cp …/…/ethercat/ . -r
gary@jxes:~/Xenomai/xenomai-v3.2.1/ethercat$ sudo ./bootstrap

• touch ChangeLog
• mkdir -p m4
• autoreconf -i
  libtoolize: putting auxiliary files in AC_CONFIG_AUX_DIR, ‘autoconf’.
  libtoolize: copying file ‘autoconf/ltmain.sh’
  libtoolize: putting macros in AC_CONFIG_MACRO_DIRS, ‘m4’.
  libtoolize: copying file ‘m4/libtool.m4’
  libtoolize: copying file ‘m4/ltoptions.m4’
  libtoolize: copying file ‘m4/ltsugar.m4’
  libtoolize: copying file ‘m4/ltversion.m4’
  libtoolize: copying file ‘m4/lt~obsolete.m4’
  configure.ac:58: installing ‘autoconf/ar-lib’
  configure.ac:57: installing ‘autoconf/compile’
  configure.ac:61: installing ‘autoconf/config.guess’
  configure.ac:61: installing ‘autoconf/config.sub’
  configure.ac:42: installing ‘autoconf/install-sh’
  configure.ac:42: installing ‘autoconf/missing’
  examples/dc_user/Makefile.am: installing ‘autoconf/depcomp’
  配置可以参考官方配置文档，比如–with-module-dir即指定内核源码路径，需要查看当前系统的module是什么：
  gary@jxes:~/Xenomai/xenomai-v3.2.1/ethercat$ ls /lib/modules
  5.13.0-30-generic 5.13.0-40-generic 5.13.0xenomai 5.15.0-60-generic 5.15.0-69-generic 5.15.106-xenomai3.2.1
  下面是本人的配置，具体视情况而定：
  gary@jxes:~/Xenomai/xenomai-v3.2.1/ethercat$ sudo ./configure --with-module-dir=/lib/modules/5.15.106-xenomai3.2.1 --enable-generic --enable-8139too=no --enable-e1000e --enable-cycles --enable-hrtimer --prefix=/opt/etherlab --with-xenomai-dir=/home/gary/Xenomai/xenomai-v3.2.1
  如果在刚开始配置的时候没有动–prefix选项，默认是安装在/opt/下的，可以查看在/opt/路径下多了一个etherlab文件夹。
  以上./configure执行失败如下：
  checking for kernel for e1000e driver… configure: error: kernel 5.15 not available for e1000e driver!
  原因是网卡与内核版本不匹配。
  下载e100e网卡：
  https://www.intel.cn/content/www/cn/zh/download/14611/15817/intel-network-adapter-driver-for-pcie-intel-gigabit-ethernet-network-connections-under-linux-final-release.html?
  具体安装方法参考：
  https://www.intel.cn/content/www/cn/zh/support/articles/000005480/ethernet-products.html
  下载后编译安装，编译时遇到错误，是与内核版本匹配问题。
  综合上面，这里只是演示下igh的源码编译，所以将e1000e网卡去掉。
  sudo ./configure --with-module-dir=/lib/modules/5.15.106-xenomai3.2.1 --enable-generic --enable-8139too=no --enable-cycles --enable-hrtimer --prefix=/opt/etherlab --with-xenomai-dir=/home/gary/Xenomai/xenomai-v3.2.1
  这样就配置成功，生成Makefile。

为了验证，于是重新下载了版本igh（带有E100E网卡）：
https://gitlab.com/etherlab.org/ethercat/-/tree/e1000e-5.10?ref_type=heads
步骤与上面一样：
gary@jxes:~/Xenomai/xenomai-v3.2.1$ sudo cp ~/Downloads/ethercat-e1000e-5.10 . -r
gary@jxes:~/Xenomai/xenomai-v3.2.1$ cd ethercat-e1000e-5.10/
gary@jxes:~/Xenomai/xenomai-v3.2.1/ethercat-e1000e-5.10$ sudo ./bootstrap
