Problema com Linker do você++

Estou fazendo uma lib para um programa opensource aqui. Eu estava compilando a lib no Dev-C++, mas devido a alguns problemas de compatibilidade, tive que passar para o você++.

No Dev-C++ estava compilando normalmente e eu estava até usando a lib no programa funcionando, só que no você++ estou tendo estes problemas no Linker:

Estas funções mensionadas pelo linker, são funções do programa que estou fazendo a lib, e todas elas foram declaradas pelos arquivos de cabeçalho que inclui:

#include "vending.h" // 's_vending' struct
#include "itemdb.h" // 'CARDX' define
#include "map.h" // 'mmysql_handle', 'map_session_data' struct
#include "pc.h" // 'map_session_data' pointers
#include "clif.h" // 'clif_cartlist'

#include "../common/cbasetypes.h"
#include "../common/mmo.h" // 'item' struct
#include "../common/nullpo.h"
#include "../common/sql.h" // 'Sql' functions
#include "../common/utils.h" // retrieve char_id
Eu dei uma pesquisada na internet, mas tudo que encontrei era o pessoal esquecendo de incluir as libs das funções que eles usavam, mas esse não é o meu caso, não tenho uma lib para estas funções...
