when tried with '$$$$' now the link line does contains $
MAKETARGET='g++ -o ././libSampleSoD.so -shared
-Wl,-Bsymbolic -Wl,-rpath,$$ORIGIN:$$ORIGIN/../lib:.:../lib
./obj/debug/sample.o -ldl
-lpthread -lgcc'
g++ -o ././libSampleSoD.so
-shared -Wl,-Bsymbolic -Wl,-rpath,$ORIGIN:$ORIGIN/../lib:.:../lib
./obj/debug/sample.o -ldl
-lpthread -lgcc
but when i checked the rpath in the binary it shows ':/../lib:.:../lib'. now
the shell is rplacing $ORIGIN. to fix this i changed RPATHFLAG to
RPATHFLAG := \$$$$ORIGIN:\$$$$ORIGIN/../lib:$(RPATHFLAG)
and now the rpath in the binary is showing $ORIGIN.
Thanks Paul for helping.
