c++ - 构建 "OpenSubdiv"时错误重载具有类似的转换

Question

我在构建 [OpenSubdiv] ( http://graphics.pixar.com/opensubdiv/docs/cmake_build.html ) 时遇到以下错误:

error C2666: 'OpenSubdiv::v3_0_0_beta::Vtr::internal::StackBuffer<TYPE,SIZE>::operator []' : 4 overloads have similar conversions

触发错误的代码行是:

            for (int i = 0; i < pVertEdges.size(); ++i) {
            cVertEdgeBuffer[i] = _refinement.getEdgeChildEdges(pVertEdges[i])[pVertInEdge[i]];
        }

实例是:

internal::StackBuffer<Index,16> cVertEdgeBuffer(_childLevel._maxValence);

StackBuffer类中的重载运算符[]好像有些歧义

template <typename TYPE, unsigned int SIZE>
class StackBuffer
{
StackBuffer();
StackBuffer(size_type size);
~StackBuffer();

public:
TYPE &       operator[](size_type index)        { return _data[index]; }
TYPE const & operator[](size_type index) const  { return _data[index]; }

operator TYPE const * () const { return _data; }
operator TYPE *       ()       { return _data; }
};

我把编译从VS2012改成VS2010，还是报错

此错误是由于 OpenSubdiv 的源代码还是由于我的 Cmake 配置造成的？我添加了 OpenSubdiv 需要的所有依赖项。

此问题已在 OpenSubdiv(开发分支)中修复 https://github.com/PixarAnimationStudios/OpenSubdiv/issues/622#issuecomment-111051840
