When we run the following commands on the hostname(DAQ machine) and the remote
frontend(Rpi):
cd $HOME/online
cp $MIDASSYS/examples/experiment/* .
make

We get errors such as
=================
On Rpi:
pi@raspberrypi:~/online/fe_test $ make
...
Missing definition of environment variable 'ROOTSYS' !

=================
On host machine
inking CXX executable frontend
/usr/bin/ld: cannot find -lmfe
/usr/bin/ld: cannot find -lmidas
collect2: error: ld returned 1 exit status
make[2]: *** [frontend] Error 1
make[1]: *** [CMakeFiles/frontend.dir/all] Error 2
make: *** [all] Error 2


The Rpi(32bit) doesn't have root installed but the host machine(64bit) does.
What can we do to fix this?

Thank you this forum has been of great help.
