Linker error on Linux with gcc 7.2

So far I've only tested with openvdb 3.0.0. It's surprising that it compiles at all with 4.0.0 (and fails only during the linking stage). Can you retry with openvdb v3 and see if that fixes the issue?

Apparently 4.0 contains some ABI changes, which might explain the linker failures.

From their release notes, section ABI changes::

• Added a NodeUnion template specialization for non-POD value types that significantly expedites construction and destruction of vector-valued grids.
• Changed Coord’s data representation to facilitate C++11 uniform initialization.
• Replaced occurrences of boost::shared_ptr with std::shared_ptr.
• Changed GridBase::copyGrid and Grid::copy to close const-correctness holes.
• Added virtual function Tree::unallocatedLeafCount.

Might try a downgrade later.

Thanks looking into this! openvdb 4 is pretty low priority, so I will close this for now.
