To be honest, it's the Linux distros that also ship openexr that had me cringing.
Debian wheezy (2.8) Debian stretch (3.7.2) * stable Debian buster (3.11.2) Ubuntu trusty (2.8) Ubuntu xenial (3.5.1) * stable Ubuntu cosmic (3.11.2) Suse tumbleweed (3.11.2) * stable Any other distros to check? I can't see any reason not to leap ahead to 3.11, because (1) versions less than 3.11 are very broken on Windows with regards to the combination of recent visual studios and boost and (2) a new OpenEXR on a Linux will ship with a distro containing at least 3.11. Make sense? ________________________________ From: Larry Gritz <l...@larrygritz.com> Sent: Friday, July 13, 2018 4:11 PM To: Nick Porcino Cc: openexr-devel@nongnu.org Subject: Re: [Openexr-devel] CMAKE_CXX_STANDARD I don't see why we would have to preserve 2.x compatibility. USD seems to need CMake 3.1 on Windows. OpenVDB needs 3.1. OIIO and OSL both require 3.2. Partio requires 3.8! So lack of support for 2.x would be in good company with other widely used packages. A few people have commented on the VFX Platform forum that it should include a minimum cmake release, so that package maintainers can count on some reasonable minimum.

So I think that if anybody actually uses CMake < 3.1, it will just silently fail to provide the right -std=c++XX flags. -- Larry Gritz l...@larrygritz.com<mailto:l...@larrygritz.com> _______________________________________________ Openexr-devel mailing list Openexr-devel@nongnu.org<mailto:Openexr-devel@nongnu.org> https://lists.nongnu.org/mailman/listinfo/openexr-devel -- Larry Gritz l...@larrygritz.com<mailto:l...@larrygritz.com>
