Strange undefined reference !!! undefined reference to `std::__default_alloc_template<true, 0>::deallocate(void*, unsigned int)'

When I am compiling my program

I am getting this error

undefined reference to `std::__default_alloc_template<true, 0>::deallocate(void*, unsigned int)'

It feels that it is not albe to find reference in the standard libraries or something. Is it some kind of lib conflict. Basically I am trying to port piece of code which was on GCC 3.1.1 开发者_开发知识库to 4.1.2

As there is compiler change I am facing this issue

Are you linking with other components still on 3.1.1 or even linking with the wrong GNU library?

---

Did you #include all the appropriate headers for the standard library components you're using?

For example,

#include <cstdlib>
#include <vector>
#include <algorithm>
#include <functional>
#include <map>
#include <set>

---

Sound to me like you are using some c++ code. 'std' namespace and the 'template'.

Try using g++ to compile your code and if that doesn´t work try to put "using namespace std;" after your include lines.

Can you please provide atleast some few lines from where the error is from?

Btw found this link with the same question asked: Here

Where they suggest installing libstdc++.
