Edit Question
Title
Body
I'm trying something spooky here. I'm trying to write C++ programs, compiled with GNU's g++, but without a dependency on libstdc++ :) but it seems that I need that for even the most basic things need it. A libstdc++ with a configurable feature set would be acceptable. The command I use is g++ -nodefaultlibs -fno-rtti -fno-exceptions -lc Without libstdc++, I get: undefined reference to `operator delete(void*)' undefined reference to `operator new(unsigned int)' undefined reference to `vtable for __cxxabiv1::__class_type_info' undefined reference to `vtable for __cxxabiv1::__si_class_type_info' undefined reference to `__cxa_pure_virtual' These aren't in libc, so is there a really light libstdc++ that implements just these things? My test code which I want to build this way currently looks like this: #include <stdio.h> template <class T> class X { public: T a; }; class A1 { public: virtual void f() = 0; virtual ~A1() {} }; class A2 : public A1 { public: virtual void f() {}; virtual ~A2() {} }; class Y { public: ~Y() {} }; int main() { X<int> A; X<float> B; Y *C = new Y; A.a = 12; B.a = 2.3; printf("A: %d; B: %f\n", A.a, B.a); A2 *a2 = new A2; a2->f(); return 0; }
