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.
