Description
Hello. I'm trying to use Eigen wrapper. Every environment is okay except MSVC.
process : intel, 64bit
c++ compiler : clang++(15.0.7)
Generator : Visual Studio 17 2022
Eigen : 3.4.0
This is my code.
#define STATS_ENABLE_STDVEC_WRAPPERS
#define STATS_ENABLE_EIGEN_WRAPPERS
#include "stats.hpp"
#include "Eigen/Dense"
#include <iostream>
int main()
{
Eigen::Vector<double, 9> probabilities;
probabilities << 0.24, 0.74, 0.12, 0.56, 0.81, 0.92, 0.65, 0.57, 0.35;
for (int32_t dof = 1; dof < 10; dof++)
auto estimated = stats::qchisq(probabilities, static_cast<double>(dof));
return 0;
}Only in MSVC, template type deduction fails. Following error occurs.
error C2672: 'stats::qchisq': no matching overloaded function found

message : With the following template arguments:

Only it makes above error on this environment(but when using std::vector wrapper, it is fine).
