You should add -fno-rtti -fno-exceptions to the CXXFLAGS in
Makefile.common.
To get rid of the operator new/delete errors you can replace
lib/c++/stub.c with a stub.cpp containing the following. Don't forget
to update the Makefile. This works for me with gcc-3.0.

---- stub.cpp ------------------
typedef unsigned size_t;
extern "C" void* malloc(size_t);
extern "C" void free(void*);
void operator delete(void* ptr) {
free(ptr);
}
void *operator new(unsigned int size) {
return malloc(size);
}

| No, I'm sorry, it doesn't seem to quite work. But it does get rid of the 3 errors at the bottom - Now it's just the operator new/delete stuff. I replaced the stub.c with the thing below, made libc++.a, and just make in lib/c++, and then go to demo (...) (21 years ago, 19-Jun-03, to lugnet.robotics.rcx.legos)
