5 years ago The functions which get multiple definition errors are the following casting ones (static inline functions):
_mm_castpd_ps⚠ | x86-64 and sse2Casts a 128-bit floating-point vector of [2 x double] into a 128-bit floating-point vector of [4 x float].

_mm_castpd_si128⚠ | x86-64 and sse2Casts a 128-bit floating-point vector of [2 x double] into a 128-bit integer vector.
_mm_castps_pd⚠ | x86-64 and sse2Casts a 128-bit floating-point vector of [4 x float] into a 128-bit floating-point vector of [2 x double].
_mm_castps_si128⚠ | x86-64 and sse2Casts a 128-bit floating-point vector of [4 x float] into a 128-bit integer vector.
_mm_castsi128_pd⚠ | x86-64 and sse2Casts a 128-bit integer vector into a 128-bit floating-point vector of [2 x double].
_mm_castsi128_ps⚠ | x86-64 and sse2Casts a 128-bit integer vector into a 128-bit floating-point vector of [4 x float].Apparently they are doubly defined in h-files in both the following Eigen installation and Clang directories:
- /usr/local/include/eigen3/Eigen/src/Core/arch/SSE/PacketMath.h
- /usr/include/clang/6.0.0/include/emmintrin.h
Note: the definitions are different.
e.g., for _mm_castpd_ps the definition of the function in the Clang directory is:
/// \brief Casts a 128-bit floating-point vector of [2 x double] into a 128-bit
/// floating-point vector of [4 x float].
///
/// \headerfile <x86intrin.h>
///
/// This intrinsic has no corresponding instruction.
///
/// \param __a
/// A 128-bit floating-point vector of [2 x double].
/// \returns A 128-bit floating-point vector of [4 x float] containing the same
/// bitwise pattern as the parameter.
static __inline__ __m128 __DEFAULT_FN_ATTRS
_mm_castpd_ps(__m128d __a)
{
return (__m128)__a;
}On the other hand, the definitions in the Eigen directory are:
#if EIGEN_COMP_PGI < 1900
// PGI++ does not define the following intrinsics in C++ mode.
static inline __m128 _mm_castpd_ps (__m128d x) { return reinterpret_cast<__m128&>(x); }
static inline __m128i _mm_castpd_si128(__m128d x) { return reinterpret_cast<__m128i&>(x); }
static inline __m128d _mm_castps_pd (__m128 x) { return reinterpret_cast<__m128d&>(x); }
static inline __m128i _mm_castps_si128(__m128 x) { return reinterpret_cast<__m128i&>(x); }
static inline __m128 _mm_castsi128_ps(__m128i x) { return reinterpret_cast<__m128&>(x); }
static inline __m128d _mm_castsi128_pd(__m128i x) { return reinterpret_cast<__m128d&>(x); }

Hello, thank you very much for making your code available.
I've read the DeepMimic paper and found it very interesting for my research. I would like to try the experiments myself.
After following the instructions I am currently stuck with the following build error and would like to ask for help. It may well be something trivial.
Thank you in advance.
