Thank you for your time. I do see the libmysqlclient installed. []# find / -name libmysqlclient_r* /usr/lib64/libmysqlclient_r.so.15 /usr/lib64/libmysqlclient_r.so.15.0.0 /usr/lib64/libmysqlclient_r.so.16.0.0 /usr/lib64/libmysqlclient_r.so.16 /usr/lib64/libmysqlclient_r.a But, I got error when I compile "make".
