Crickets. I'm therefore going to assume that MSVS 2015 is the minimum. Not 2013, which platform.h sure makes look like nobody could possibly have been relying on it.
In light of that, I'm going to update the documentation to also say MSVS2015 minimum. If somebody pipes up later that this is an unwise choice as we go into calendar 2019, then we can always walk it back somehow. Better to add support for an older compiler later, than try to remove support for a compiler we advertised on release day to be supported. > On Nov 24, 2018, at 5:45 PM, Larry Gritz <[email protected]> wrote: > > I *think*, based on https://msdn.microsoft.com/en-us/library/hh567368.aspx > <https://msdn.microsoft.com/en-us/library/hh567368.aspx> , that VS 2015 is > the actual minimum version we need, since VS2013 doesn't appear to support > constexpr, noexcept, and some other C++ features we definitely have in our > code, and I haven't heard anybody complain. > > It also looks like src/include/OpenImageIO/platform.h (lines 92-109) will > reject VS2013 (_MSC_VER >= 1900 is true only for VS2015+). > > So I believe that Visual Studio 2015 has, for all practical purposes, been > our minimum for quite some time.
