The problem of driver installation between ethercat and linuxcnc

Hello, now I have a problem, I hope you can help solve it, thank you very much
I have an incredible problem with installing linuxcnc and ethercat When you do the ec-debianize installation, after sudo. / get _ source.sh, you need to do the following sudo dpkg-build package, but the problem is that I ' m confused for a long time, and I hope you can help, thank you again！
This salute

did you check with dpkg-checkbuilddeps ??

has the get_source scripted worked completly. Shoud display a longer lister of patches that get applied.....

another case could be missing kernel headers:sudo apt install linux-headers-$(uname -r)

The problem is still not solved, hope there is a more effective way
