[Bf-committers] Building with openvdb

[Dave Plater]

Hi, I'm trying to introduce openvdb into the blender build. I've created 
the openvdb package version 4.0.1 (Very memory hungry build) and then am 
attempting to build blender but I get a build failure in
intern/openvdb/intern/openvdb_writer.cc:

Full build log at:
https://build.opensuse.org/build/home:plater:blender/openSUSE_Tumbleweed/x86_64/blender/_log
This is built with gcc 7 my 42.2 build with gcc48 fails to transfer the 
-std=c++11 flag to the build, log at:
https://build.opensuse.org/build/home:plater:blender/Leap_42.2/x86_64/blender/_log
Have a choice for gcc5 and 6 but 42.2 defaults to gcc48.

Will appreciate any help.
Thanks
