Try linking the following two C++ sources together:
struct a
{
virtual void g();
virtual void f(){}
};
int main() { a b; b.f(); b.g(); }
---- cut -----
struct a
{
virtual void g();
virtual void f(){}
};
void a::g() {}
We get an error:
/tmp/ccFSWYxL.o(.eh_frame+0x11): undefined reference to `__gxx_personality_v0'
/tmp/ccUWWgfl.o(.gnu.linkonce.r._ZTI1a[typeinfo for a]+0x0): undefined reference to `vtable for
__cxxabiv1::__class_type_info'
This is relative new binutils too:
GNU ld version 2.15.94 20041104
Also this breaks building libjava on the same target.
