I found it just not support some Intrinsics on Visual Studio 2005.
so I add some Intrinsics on btScaler.h to let it work.

            #define BT_USE_SSE_IN_API
            #endif //BT_USE_SSE
            #include <emmintrin.h>
            #if (_MSC_VER == 1400)
            inline float _mm_cvtss_f32(__m128 A) { return A.m128_f32[0]; }
            inline __m128 _mm_castpd_ps(__m128d PD) { union { __m128 ps; __m128d pd; } c; c.pd = PD; return c.ps; }
            inline __m128d _mm_castps_pd(__m128 PS) { union { __m128 ps; __m128d pd; } c; c.ps = PS; return c.pd; }
            inline __m128i _mm_castps_si128(__m128 PS) { union { __m128 ps; __m128i pi; } c; c.ps = PS; return c.pi; }
            inline __m128 _mm_castsi128_ps(__m128i PI) { union { __m128 ps; __m128i pi; } c; c.pi = PI; return c.ps; }
            #endif
