linking problems - __cxa_pure_virtual

[Andy Howell <AndyHowell@xxxxxxxxxxxxx>]

I'm having some linking problems a can't work out. I'm using GCC 3.3 on 
Solaris 8. I found lots of references to __cxa_pure_virtual on google, 
but nothing about how to fix it. The missing symbols are:

__cxa_pure_virtual
vtable for __cxxabiv1::__si_class_type_info
vtable for __cxxabiv1::__vmi_class_type_info
operator new[](unsigned)
vtable for __cxxabiv1::__class_type_info
operator delete(void*)
operator new(unsigned)
__gxx_personality_v0
operator delete[](void*)

Thanks,

   Andy
