Error with GMP with C++ in Netbeans (Windows 64-Bit)

I'm doing a project for school in which I am doing all kinds of different calculations involving prime numbers. These numbers tend to go quite big, hence I went looking for an arbitrary precision library. I decided to go for GMP since I had used it earlier in Game Maker (a relatively unknown program) since someone had made a dll for it.

Now, I have followed the install manual and went ahead to compile GMP. I had great difficulty in doing this as I am totally unfamiliar with UNIX and cygwin. Now that I have tried to include gmpxx.h in Netbeans for a test program, things are going wrong. My code is as follows:

#include <cstdlib>
#include <iostream>
#include <stdio.h>
#include <gmpxx.h>
#include <stdarg.h>

using namespace std;

int main()
{
    mpz_t a;
    mpz_init(a);
    //cout << mpz_probab_prime_p(a,20);
    mpz_clear(a);
}

For both mpz_init and mpz_clear I am getting the same error:

relocation truncated to fit: R_X86_64_PC32 against undefined symbol '__gmpz_[init/clear]'

I am just guessing, but the problem could be any of the following:

  • Wrongly compiled
  • Bad code
  • Improper includes/links

It could very well be the latter, although I have experimented with adding directories for the header files and such. How would I fix this error?

Thanks in advance!

Edit: Since this is my first post, could you point out what I need to clarify in order to make this question answerable?

Edit2: This is the compiling log in Netbeans:

Edit3: As @rubenvd pointed out, the real error is this:

/cygdrive/e/Documents/NetBeansProjects/FirstTestGMP/main.cpp:22: undefined reference to `__gmpz_init'
Solution

  • Thanks everyone! I fixed my problem by going to: Properties > Build > Linker > Libraries > Add Library Then adding gmp.a and gmpxx.a, which I found in the gmp directory that I compiled.
