Hello,

 I installed pari-2.17.1 on Linux Ubuntu in the folder $HOME/pari. avx 
could not be found in C lib, but all tests seem to run fine.

 Now I am using gcc (Ubuntu 13.3.0-6ubuntu2~24.04) 13.3.0, and while my 
c code compiles all right, my simple test program (named "using_pari.c")

#include "pari/pari-2.17.1/include/pari/pari.h"

int main(void)
{
 GEN i,j,k;
 size_t size;
 ulong maxprime;

 size = 500000;
 maxprime = 2;
 pari_init(size, maxprime);

 i=gen_1;
 j=stoi(3);
 k=gadd(i,j);
 printf("1+3=%s",GENtostr(k));
 return 0;

}

does not compile:

leitner@laptop:~$ gcc using_pari.c

 I am inexperienced with linker issues. Could you please help me to fix 
the problem?

 Cheers,
