I tried to compile my project in visual studio 2017 but with vs2015 (v140) platform toolset, and got many c2719 errors. With vs2017(v141) toolset, everything is fine.

Hi @zhengli233,

We do not support VS 2015 but could you give us at least one full compiler error to identify the problem more precisely?

Hi @kouchy ,

Here is my simple test code with "/arch:AVX2" compile command:

#include "stdafx.h"
#include "mipp.h"

int main()
{
	uint8_t * arr = new uint8_t[256];
	memset(arr, 1, sizeof(uint8_t) * 256);

	mipp::Reg<uint8_t> vec1(arr);

	return 0;
}

and here are the errors:

Hi @zhengli233,

Thx for the full trace.
At this time I don't understand why the compiler fails to align some variables :-/.

I will think about it.
