Hi,
I am having some difficulties passing a vector of type std::vector<float128> to a function. I'm getting multiple errors out. The first few of which are:
*tql2.cpp:13:50:* *error: *‘*float128*’ was not declared in this scope
void tql2(const int nm, int n, const std::vector<float128> & d, const std::vector<float128> & e, const std::vector< std::vector<float128> > & z, int ierr)

The first few lines of my code are:
#include <boost/multiprecision/float128.hpp>
#include <boost/math/cstdfloat/cstdfloat_types.hpp>
#include <boost/math/cstdfloat/cstdfloat_limits.hpp>
#include <boost/math/cstdfloat/cstdfloat_cmath.hpp>
#include <boost/math/cstdfloat/cstdfloat_iostream.hpp>
extern"C"{
#include <quadmath.h>
}
#include <iostream>
#include <vector>
#include <iterator>
voidtql2(constintnm, intn, conststd::vector<float128> & d, conststd::vector<float128> & e, conststd::vector< std::vector<float128>
& z, intierr)
{
using namespace boost::multiprecision;
...
}
Not sure where I am going wrong? Any advice?
Try moving the 'using namespace' line just after your header file includes.
