I tried the sudo chown. Not sure what you meant by "the one with .git in it",
I did it from the directory above the src.
I got some errors and redid ./configure --with-realtime=uspace
"make" did a lot of stuff, but ended with:
Linking python module gcode.so
g++ -L/home/atxhacker/linuxcnc-2.7.4/lib
-Wl,-rpath,/home/atxhacker/linuxcnc-2.7.4/lib -shared -o ../lib/python/gcode.so
objects/emc/rs274ngc/gcodemodule.o ../lib/librs274.so.0 -lstdc++
Linking ../rtlib/abs.so
ld: no input files
make: *** [../rtlib/abs.so] Error 1
then I did "sudo make setuid"
hal/user_comps/vfdb_vfd/Submakefile:11: warning: overriding commands for target
`../bin/vfdb_vfd'
hal/user_comps/vfdb_vfd/Submakefile:11: warning: ignoring old commands for

chown root ../bin/rtapi_app
chmod 4750 ../bin/rtapi_app
source ../scripts/rip-environment
This script only needs to be run once per shell session.
type "linuxcnc" , loads, lets me select a HAL file, then:

as well as in the output of the shell command 'dmesg' and in the terminal
