Question

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.   
./Debug/mysql_api.o: In function `mainuu()':

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.
