I am seeking some help trying to build the ethercat master on Alma9. I am trying to first just build the simplest configuration I can (i.e. not an RT kernel), on a VMWare VM (not sure if this will create a problem). I have installed
<code>kernel-devel</code> and it looks like I have the kernel sources in <code>/usr/src/kernels/5.14.0-427.37.1.el9_4.x86_64</code></div>
