Error installing RMySQL (MySQL 5.5.37 in Ubuntu 14.04 )

Every time I try installing RMySQL I get the following error:

Warning message:

Seemingly, it cannot find mysql.h and I searched and changed the path to

export PKG_CPPFLAGS="-I/usr/R/include/mysql/mysql.h"

but it was not successful. There're many people who have had the same issue but non of their solutions (if existed) worked for me. I'd appreciate any comment or help.

#Update: Issue Resolved#
