"undefined reference to `mysqlpp::Connection::connect(char const*, char const*, char const*, char const*, unsigned int)'"

My code:


// Database stuffs.
mysqlpp::Connection awi_mysql_conn(false);
// Vars for the command line.
TCLAP::ValueArg<char*awi_tclap_mysql_pwd("p","mysql_pwd","MySQL
Password",true,"admin","string");
TCLAP::ValueArg<char*awi_tclap_mysql_usr("u","mysql_usr","MySQL
User",true,"root","string");
TCLAP::ValueArg<char*awi_tclap_mysql_db("d","mysql_db","MySQL
Database",true,"awi","string");
TCLAP::ValueArg<char*awi_tclap_mysql_srv("s","mysql_srv","MySQL
Server",true,"locahost","string");
TCLAP::SwitchArg awi_tclap_open_mode("o","open_mode","Use
Mode",false);
// Stuffs for the system command line. Not the internal CLI.
TCLAP::CmdLine awi_cmd("Artifitical World Intelligence",'
',awi_version,true);
// Send the arguments to TCLAP.
awi_cmd.add(awi_tclap_mysql_pwd);
awi_cmd.add(awi_tclap_mysql_usr);
awi_cmd.add(awi_tclap_mysql_db);
awi_cmd.add(awi_tclap_mysql_srv);
awi_cmd.add(awi_tclap_open_mode);
// Parse the command line.
awi_cmd.parse(argc,argv);
// Get values.
char* awi_mysql_db = awi_tclap_mysql_db.getValue();
char* awi_mysql_srv = awi_tclap_mysql_srv.getValue();
char* awi_mysql_usr = awi_tclap_mysql_usr.getValue();
char* awi_mysql_pwd = awi_tclap_mysql_pwd.getValue();
bool awi_open_mode = awi_tclap_open_mode.getValue();
// Connect to the database using command line values.

if(awi_mysql_conn.connect(awi_mysql_db,awi_mysql_s rv,awi_mysql_usr,awi_mysql_pwd)){
std::cout << "Database connection successful." << endl;
}else{
std::cout << "ERRR: Unable to connect to database." << endl;
exit(EXIT_FAILURE);
};

The error:


Main.cpp:(.text+0x16e9): undefined reference to
`mysqlpp::Connection::connect(char const*, char const*, char const*, char
const*, unsigned int)'


Does anyone have just the slightest idea what I'm doing wrong? My compiler
command is:


g++ \
-I./lib/MySQLPP -I./lib/TCLAP -I./lib/Miscellaneous \
`mysql_config ` `mysql_config ` `mysql_config ` \
-lmysqlpp -lpthread -lnsl -lresolv \
./src/Main.cpp -o ./bin/AWIWorldServer;
>

To me this seems all good Any ideas?

Thanks.
