Xcode4.6.3 内で llvm-gcc-4.2 を使用して「x265」ソースをコンパイルすると、奇妙なエラーが報告されました。ただし、x265::MotionReference のクラス宣言は、reference.h で完了しています。

#ifndef X265_REFERENCE_H
#define X265_REFERENCE_H

#include "primitives.h"
#include "picyuv.h"
#include "lowres.h"
#include "mv.h"

namespace X265_NS {
// private x265 namespace

struct WeightParam;

class MotionReference : public ReferencePlanes
{
public:

    MotionReference();
    ~MotionReference();
    int  init(PicYuv*, WeightParam* wp, const x265_param& p);
    void applyWeight(int rows, int numRows);

    pixel*  weightBuffer[3];
    int     numInterpPlanes;
    int     numWeightedRows;

protected:

    MotionReference& operator =(const MotionReference&);
};

親クラスはヘッダーファイル「lowres.h」で定義されています。
