Initially my openSIPS server menuconfig tool worked properly
When I reinstalled mysql-client by ('sudo apt-get remove mysql-client' later install using 'sudo apt-get install mysql-client') the menuconfig tool of openSIPS gives some warning.
You have enabled the 'db_mysql' module, so please install ' development librariePress any key to continue
I tried by installing 'libmysqlclient-dev' but it didn't work..
