Example code compilation fails.

[norouzzadeh]

I have compiled and installed the openvdb latest commit in Ubuntu 16.04 with boost 1.58 successfully.
During the compilation of any cookbook examples, i get the following error:

In function openvdb::v4_0_1::math::AffineMap::postRotate(double, openvdb::v4_0_1::math::Axis) const': /usr/local/include/openvdb/math/Maps.h:619: undefined reference to openvdb::v4_0_1::math::simplify(std::shared_ptropenvdb::v4_0_1::math::AffineMap)'

The simplify function in OpenVDB library is defined as:
openvdb::v4_0_1::math::simplify(boost::shared_ptropenvdb::v4_0_1::math::AffineMap)

But in the Maps.h it is defined as
OPENVDB_API SharedPtr simplify(SharedPtr affine);

where
template using SharedPtr = std::shared_ptr;

I think that, it shall be declared as boost::shared_ptr instead of std::shared_ptr.

Hi @norouzzadeh,

I believe the issue is that you're compiling the OpenVDB library with ABI=3 and codebook examples with ABI=4.

SharedPtr is actually defined as follows:

• ABI=3 boost::shared_ptr
• ABI=4 std::shared_ptr

Provided that you use the same ABI for both (the library and the binary), they should be compatible with each other.

Hi @danrbailey ,

That's right. Thanks a lot.
