Error for the header file of goblin library in c++

I am trying to use Goblin library which is used for special network algorithms. This library provides some header files and objects in C/C++. So, you can easily add a header file to your program and u开发者_StackOverflow社区se some special classes and functions.

Unfortunately, when I add the header file, I get error. In the following you can see the simple code and error.

Source:

#include<goblin.h>

int main()
{
    return 0;
}

Error:

$ g++ -o test.o test.cpp
