Can not compile the SIMD project in Windows for ARM64, using Cmake. #266
Description
Issue Description
I encountered an issue while trying to compile the library for ARM64 on Windows 11 using Microsoft Visual Studio 2022. I received the following error:
SimdExtract.h(328,32): error C2084: function 'float32x4_t Simd::Neon::Extract4Sums(const float32x4_t &,const float32x4_t &,const float32x4_t &,const float32x4_t &)' already has a body SimdExtract.h(319,33): see previous definition of 'Extract4Sums'
Issue Details
Root Cause:
From line 319, in SimdExtract.h
SIMD_INLINE float32x4_t Extract4Sums(const float32x4_t & a0, const float32x4_t & a1, const float32x4_t & a2, const float32x4_t & a3)
{
float32x4x2_t b0 = vzipq_f32(a0, a2);
float32x4x2_t b1 = vzipq_f32(a1, a3);
float32x4x2_t c0 = vzipq_f32(b0.val[0], b1.val[0]);
float32x4x2_t c1 = vzipq_f32(b0.val[1], b1.val[1]);
return vaddq_f32(vaddq_f32(c0.val[0], c0.val[1]), vaddq_f32(c1.val[0], c1.val[1]));
}
In line 328
SIMD_INLINE uint32x4_t Extract4Sums(const uint32x4_t& a0, const uint32x4_t& a1, const uint32x4_t& a2, const uint32x4_t& a3)
{
uint32x4x2_t b0 = vzipq_u32(a0, a2);
uint32x4x2_t b1 = vzipq_u32(a1, a3);
uint32x4x2_t c0 = vzipq_u32(b0.val[0], b1.val[0]);
uint32x4x2_t c1 = vzipq_u32(b0.val[1], b1.val[1]);
return vaddq_u32(vaddq_u32(c0.val[0], c0.val[1]), vaddq_u32(c1.val[0], c1.val[1]));
}
Additional Information
in the file arm_neon.h inside Visual studio, both uint32x4_t, float32x4_t have the type __n128
- Operating System: Windows 11
- Compiler: Microsoft Visual Studio 2022
Thank you for your assistance in resolving this issue.

Hi. I changed names of functions Extract4Sums to Extract4Sums32f and Extract4Sums32u. I hope it will resolve this issue.
P.S. I can't check it because i have no access to Windows on ARM64.
