BigIntegerLibrary.hh

[dilver]

I downloaded a library that is in this link:

https://mattmccutchen.net/bigint/

then when I tried to run this code

#include<iostream>
#include "BigIntegerLibrary.hh"
using namespace std;
 int main()
{
      
BigInteger a = 65536;
cout << (a * a * a * a * a * a * a * a);

}

I got this errors:
undefined reference to `BigInteger::BigInteger(int)'
undefined reference to `operator<<(std::ostream&, BigInteger const&)'
C:\collect2.exe [Error] ld returned 1 exit status
BigInteger::multiply(BigInteger const&, BigInteger const&)'

I am totally confused? what does these errors mean and how to solve the problem?

This library was last updated more than 5 years ago...


Also you may not have the header/source files in the same directory as your project.

Try including the direct path to the header.

here's his source by the way. https://mattmccutchen.net/bigint/bigint.git/tree/66d84fa2e51e36706556be30cb38c8026db32e46

Though I personally would just use boost's big int or make one, should be fairly trivial for basic bigint.

Have you read the README file?

The following worked on Linux:
g++ main.cpp Big*.cc -o dilver\'s_app
