At first, small program:
#include <mysql++.h>
using namespace mysqlpp;
void mainuu ()
{ Connection conn("mysql", "localhost", "root", "pwd");}
If I compile it as one file in CodeLite or in such way:
g++ -I/usr/include/mysql -I/usr/include/mysql++ -lmysqlclient -lmysqlpp -o Test mysql_api.cpp
it's ok but, when I try to build whole project with this file I get this:
g++ -o ./Debug/server ./Debug/main.o ./Debug/log.o ./Debug/packet.o ./Debug/mysql_api.o -L.

Here is CodeLite g++ compiler settings:
-g -I/usr/include/mysql -I/usr/include/mysql++ -lmysqlclient -lmysqlpp -L/usr/lib/mysql -L/usr/lib/mysql++ -lmysql++
Looks like you need to edit CodeLite project settings and add these settings -lmysqlclient -lmysqlpp that you pass in command line. Fill Library Path and Libraries fields on Linker tab.
