Hi, I am trying run test suite for bison but its throwing some error- g++: error: ./examples/calc++/calc++-scanner.cc: No such file or directory Found some work around- cp Makefile Makefile.bak sed -i '/calc++/d' Makefile make check This helped me to run suite without error. But is it correct solution? Regards, Aditya Tayade This message contains information that may be privileged or confidential and is the property of the KPIT Technologies Ltd.
