Hello guys,
My name is Vasu and i was working on ITER project for s7plc configuration with epics and for so i got some help from https://www.slac.stanford.edu/grp/ssrl/spear/epics/site/s7plc/s7plc.html  and https://github.com/epicsdeb/s7plc but while compiling am facing problem like this..<

make -C O.linux-x86_64 -f ../Makefile TOP=../.. \
    T_A=linux-x86_64 install
