HalfTest Example - Compile Error with VS2013 (64-bit)

[Adam Hartshorne]

Hi,

Using the latest version of Ptex from Git repo, after using Cmake to create VS projects, Ptex library compiles but the halftest demo returns the following 2 errors.

halftest.obj : error LNK2001: unresolved external symbol "public: static unsigned int * Ptex::v2_2::PtexHalf::h2fTable" (?h2fTable@PtexHalf@v2_2@Ptex@@2PAIA)

3>halftest.obj : error LNK2001: unresolved external symbol "public: static unsigned short * Ptex::v2_2::PtexHalf::f2hTable" (?f2hTable@PtexHalf@v2_2@Ptex@@2PAGA)

A couple of months ago I built this library as a 32-bit and I don't remember any issues, so I have to presume it is something to do with 64-bit.

Any help much appreciated.

The PtexHalf tables switched to static generation quite a while ago, and I don't know of any build problems. The CMakeLists.txt file includes PtexHalf.cpp which defines and exports the tables. I do see there was a fix for the static tables on 3-29-2016 for building a Windows DLL, but I don't personally build on Windows so I don't know what other problems there might be. Could it be you have an older Ptex library in your build path?

I think you might have been correct.

I cleaned out my local github clone and  vs build directory, and started from scratch. It is now building without error.
