Undefined symbols in C++ project

Hi there

I sent this mail just before WWDC and during an outage of the mailing list. As I have received no response yet I try again in the hope that someone is able to help me.

I am trying to compile a rather large C++ project in Project Builder. The project compiles just fine in CodeWarrior 8 for Mac. Actually the compilation also succeeds with Project Builder but the linker complains with the lines below (I have separated the individual lines for clarity). I have no idea where to look for these symbols as I can't find where in the code they are referenced. If you have any suggestions of which libraries to include or how to find out where these symbols are referenced please let me know.
If it is of any help I'm using the 3rd party library wxWindows which also has been compiled in Project Builder.

ld: Undefined symbols:
_link_dummy_func_m_style()

task_for_pid(unsigned, int, unsigned*)

mach_port_deallocate(unsigned, unsigned)

std::basic_string<wchar_t, std::char_traits<wchar_t>, std::allocator<wchar_t> >::c_str() const

std::basic_string<wchar_t, std::char_traits<wchar_t>, std::allocator<wchar_t> >::length() const

std::basic_string<wchar_t, std::char_traits<wchar_t>, std::allocator<wchar_t> >::assign(wchar_t const*, unsigned long)
