RTAI, LinuxCNC and the test suite all have to be built against each other.
Please use the LinuxCNC install ISO to build your controller.

What is the actual path to the rtai modules? It is typically not /usr/realtime. Mine is (today) /usr/realtime-4.14.174-rtai-amd64
But, the fact is, that I spent weeks of my time doing this so you didn't have to. If you are doing it for fun, then that's great, and the more folk building RTAI from scratch the better (especially as a new RTAI version was released _today_)
Following the NTULINUX instructions normally goes smoothly (following the RTAI ones, less so)

I am simply interested, because I found that there are very few documentation about compiling from source code (including compiling linux kernel, compiling RTAI (compatible with linuxcnc), and finally compiling linuxcnc)

I used the default path to compile and install RTAI, isn't it /usr/realtime? How to find the actual path to the rtai modules？As the same time ,thank all of you very much for the contribution, I feel linuxcnc is very very great!

This is the linuxcnc configuration information and compilation information? Is my rtai still incorrect? Why is there such a thing as pcl720?

It's a card supported by Linuxcnc.
From
"your_linuxcnc_base_dir"/src/hal/drivers/pcl720.comp
component pcl720 """Driver for the Advantech PCL 720 card.""";
description """This driver supports the Advantech PCL720 ISA card. It might
work with the PCI version too, but this is untested.
It creates hal pins corresonding to the digital inputs and outputs, but does
not support the the counters/timers.""";
It wouldn't be a gcc 5.4 issue ?
