Answer 1

During compilation with g++ via make define LIBRARY_PATH if it may not be appropriate to change the Makefile with the -Loption. I had put my extra library in /opt/lib so I did:

$ export LIBRARY_PATH=/opt/lib/

and then ran make for successful compilation and linking.

To run the program with a shared library define:

$ export LD_LIBRARY_PATH=/opt/lib/

before executing the program.
