you are compiling with C++14. Tell your compiler to use C++17 and it will probably work. I think that's CMAKE_CXX_STANDARD=17

[lgritz]

Does OpenVDB 10.1 require a C++17 minimum?

[MehdiChinoune]

It buil

It works, Thanks.
Still there is no mention of C++17 requirement in the release notes.

[lgritz]

Actually: https://github.com/AcademySoftwareFoundation/openvdb/blob/master/cmake/config/OpenVDBVersions.cmake#L17

I will make a PR for OIIO that gives appropriate warnings when building against an OpenVDB that's so new that it requires C++17.

[lgritz]

Yeah, looking at older versions of OpenVDB source, it looks like through 9.x, C++14 was adequate, but for OpenVDB >= 10.0, C++17 was their minimum.

It was building fine against 10.0.1, Maybe they started using C++17 features with 10.1.0
