Can you please send me the output of the failing configure run, starting
with the RTAI 24.1.x detection? Does your error msg looks like this?

checking for RTAI 3 installation... /tmp/usr/realtime
checking for RTAI 3 version... 3.0

configure: error: *** header not found or working, please check RTAI installation
If you have the same problem this patch should fix it...Don't forget to
run ./autogen.sh to regenerate the buildsystem...
