Standard Library linking problems

Hey all,

(I'm using Xcode 2.4, building a project for archs "ppc i386".)

I've read the thread "Re: linking against stdandard libraries":
	http://lists.apple.com/archives/xcode-users/2005/Jul/msg00495.html

...which states that linking with Standard C libraries should be automatic, but I'm having trouble with some pesky "Undefined symbols" which go away if I manually link stdc++:

	___gxx_personality_v0
	vtable for __cxxabiv1::__class_type_info
	vtable for __cxxabiv1::__si_class_type_info
	___cxa_pure_virtual
	vtable for __cxxabiv1::__pointer_type_info
	___cxa_begin_catch
	___cxa_end_catch
	vtable for __cxxabiv1::__vmi_class_type_info
	___cxa_allocate_exception
	___cxa_throw

I have LINK_WITH_STANDARD_LIBRARIES set, and can't find any other settings which seem to affect this.

...so my questions are: - under what circumstances are the Standard Libraries passed or not? - can I examine the Ld command line to verify what's happening? (i.e. what parameters would show the standard libraries being passed, or should I be seeing an explicit "-L" parameter for the requisite standard libs?) Thanks, --Dave
