Question

I am just trying to make a vector, but it gives me a huge error and I am following a working example from my other project. The code:

#include <stdio.h>
#include <stdlib.h>
#include <vector>
using namespace std;

struct organism {
    bool One;
    bool Two;
};
std::vector<organism> organisms;

int main() {
    printf("Content-type: text/html\n\n");
    printf("TEST");
    printf(getenv("QUERY_STRING"));

    return 0;
}

The error:

> "make" 
C:/MinGW/bin/gcc.exe -o build/e2.exe source/main.cpp
C:\Users\Stephen\AppData\Local\Temp\ccc0a0w2.o:main.cpp:(.text$_ZN9__gnu_cxx13new_allocatorI8organismE10deallocateEPS1_j[__gnu_cxx::new_allocator<organism>::deallocate(organism*, unsigned int)]+0xd): undefined reference to `operator delete(void*)'

"make": *** [build] Error 1

I can compile it if I comment out std::vector<organism> organisms; but I have no clue what’s wrong with that line. It’s exactly the same in my other project, which compiles fine.

You need to compile with g++.exe instead of gcc.exe so that it will know it needs to link with the C++ library.
