xio std::abs(): Call of overloaded is ambiguous #1946

Open PeterMoresco opened 4 years ago

PeterMoresco commented 4 years ago

Hi, I've been playing around with xtensor and I've got an error on the line that prints the content to the screen. I've searched a little and didn't found any report of this, so I'm posting here for u guys to help me. Thanks. I'm currently using Ubuntu 18.04LTS, and compiled the file using g++ (7.4.0).

`#include

include "xtensor/xarray.hpp"

include "xtensor/xio.hpp"

include "xtensor/xview.hpp"

include

using namespace std;

int main() { xt::xarray a = xt::arange(324); // cout << a << endl; cout << "\n"; a.reshape({3, 2, 4});`

@PeterMoresco this works in the CI: https://travis-ci.org/xtensor-stack/xtensor/jobs/654343139?utm_medium=notification&utm_source=github_status Are you sure the error comes from printing the array?

How do you compile your example? Which flags do you use? Also on which platform are you compiling?

Can you add #include <cstdlib> at the beginning of your file and see if it fixes the problem?
