Support for c++17 and/or c++20 #700

emmenlau · 2022-04-07T10:39:54Z

It would be great if the xtensor-stack could support c++17 and/or c++20. Currently I fail to build with Clang when c++17 or c++20 is enabled. Here is one of the errors I get the xsimd:

I second that opinion. We should be compatible with C++14/17/20 while keeping C++11 support.

Related to #700

Since #703 has been merged, the swizzle ambiguity is solved, nice work @serge-sans-paille (and @JohanMabille ).

Actually both of my original build issues have been resolved, thanks a million @serge-sans-paille , I get a working c++20 build now. Fixing this issue as solved, and will open a new one for the mandelbrot example.
