Linker error

openvdb\openvdb\libopenvdb.lib : fatal error LNK1248: image size (1017E3216) exceeds maximum allowable size (FFFFFFFF)
[155/156] Building CXX object openvdb_cmd\vdb_print\CMakeFiles\vdb_print.dir\main.cc.obj
ninja: build stopped: subcommand failed.

vdb_print is not critical to me at this point so I can remove it from the build but reporting this anyway.

Hey @nyue this is usually related to explicit template instatiation. We should probably turn this off on Windows. Try configuring with -D USE_EXPLICIT_INSTANTIATION=OFF

That works for me.

I have a new issue with the Windows build

The Ninja build encountered multiple build rules but only if I build the AX stuff.

Ah this looks to be a bug in our CMake, both the shared and static builds of AX are producing the same library name.

You can either disable the static/shared build with OPENVDB_AX_SHARED=ON|OFF or OPENVDB_AX_STATIC=ON|OFF or add:

  if(WIN32)
    set_target_properties(openvdb_ax_static PROPERTIES PREFIX "lib")
  endif()

to somewhere in openvdb_ax/CMakeLists.txt:

https://github.com/AcademySoftwareFoundation/openvdb/blob/41bb1279c2c96d0d09614bc57830da0184002c51/openvdb_ax/openvdb_ax/CMakeLists.txt#L304-L308

I'll make the latter change to master
