Develop question

Hello: I don't know where i should post this question, please suggest me. My issue is at linking time. I', trying to develop an example program from c++ use as compiler g++ in Linux without any problem but where I try to compile and link the same sample source code in wind32 usin mingw32-g++ I get too many linking problems as you can see in the next lines: .objs/util.o:util.cpp|| undefined reference to `__imp___ZN8ITStringC1EPKc'| .objs/util.o:util.cpp|| undefined reference to `__imp___ZN8ITStringC1EPKc'| .objs/util.o:util.cpp|| undefined reference to `__imp___ZN8ITStringC1EPKc'| .objs/util.o:util.cpp|| undefined reference to `__imp___ZN8ITStringC1EPKc'| .objs/util.o:util.cpp|| undefined reference to `__imp___ZN8ITDBInfoC1ERK8ITStringS2_S2_S2_'| .objs/util.o:util.cpp|| undefined reference to `__imp___ZN8ITStringD1Ev'| .objs/util.o:util.cpp|| undefined reference to `__imp___ZN8ITStringD1Ev'| .objs/util.o:util.cpp|| undefined reference to `__imp___ZN8ITStringD1Ev'| .objs/util.o:util.cpp|| undefined reference to `__imp___ZN8ITStringD1Ev'| .objs/util.o:util.cpp|| undefined reference to `__imp___ZN8ITStringD1Ev'| .objs/util.o:util.cpp|| more undefined references to `__imp___ZN8ITStringD1Ev' follow| .objs/util.o:util.cpp|| undefined reference to `__imp___ZN12ITConnectionC1ERK8ITDBInfo'| .objs/util.o:util.cpp|| undefined reference to `__imp___ZN12ITConnection4OpenEv'| .objs/util.o:util.cpp|| undefined reference to `__imp___ZNK14ITErrorManager5ErrorEv'| .objs/util.o:util.cpp|| undefined reference to `__imp___ZN7ITQueryC1ERK12ITConnection'| .objs/util.o:util.cpp|| undefined reference to `__imp___ZN8ITStringC1EPKc'| .objs/util.o:util.cpp|| undefined reference to `__imp___ZN7ITQuery10ExecOneRowERK8ITStringPP8IUnknown'| .objs/util.o:util.cpp|| undefined reference to `__imp___ZN8ITStringD1Ev'| .objs/util.o:util.cpp|| undefined reference to `__imp___ZN8ITStringD1Ev'| .objs/util.o:util.cpp|| undefined reference to `__imp___ZN7ITQuery7NextRowEPP8IUnknown'| .objs/util.o:util.cpp|| undefined reference to `__imp___ZN12ITConnection5CloseEv'| .objs/util.o:util.cpp|| undefined reference to `ITQuery::~ITQuery()'| .objs/util.o:util.cpp|| undefined reference to `ITQuery::~ITQuery()'| .objs/util.o:util.cpp|| undefined reference to `ITConnection::~ITConnection()'| .objs/util.o:util.cpp|| undefined reference to `ITConnection::~ITConnection()'| .objs/util.o:util.cpp|| undefined reference to `ITDBInfo::~ITDBInfo()'| .objs/util.o:util.cpp|| undefined reference to `ITDBInfo::~ITDBInfo()'| ||=== Build finished: 27 errors, 0 warnings (0 minutes, 0 seconds) ===| I don't know which missing library must be linked on win.
