I've spent 5 hours trying to understand the reason for an undefined
reference, so I'm asking for some help.
The code
--------------------
#include <cstdlib>
#include <gmp.h>
#include <cln/cln.h>
using namespace std;
using namespace cln;
const cl_univpoly_complex_ring CZ = find_univpoly_ring(cl_C_ring);
struct parameter { cl_N z0; cl_UP_N p(); };
int main(void) {
cl_UP_N q=CZ->create(1);
q.set_coeff(1, 1);
q.set_coeff(0, -1);
q.finalize();
parameter param;
param.z0=1;
param.p()=q;
}
--------------------
produces the error message
--------------------
/tmp/ccZPl6fM.o: In function `main':
test.cpp:(.text+0xc6): undefined reference to `parameter::p()'
collect2: error: ld returned 1 exit status
--------------------
What am I doing wrong?
Note: replacing p() with p, which would make more sense to me, generates
compiler errors.
Thanks,
Mike
