error: 'uint16_t' undeclared?
提问by pandoragami
I have the code
我有代码
#include <emmintrin.h>
#include <stdio.h>
void print128_num(__m128i var)
{
uint16_t *val = (uint16_t*) &var;
printf("Numerical: %i %i %i %i %i %i %i %i \n",
val[0], val[1], val[2], val[3], val[4], val[5],
val[6], val[7]);
}
int main(void)
{
__m128i a = _mm_set_epi32(4, 3, 2, 1);
__m128i b = _mm_set_epi32(7, 6, 5, 4);
__m128i c = _mm_add_epi32(a, b);
print128_num(c);
return 0;
}
and I'm getting an error where uint16_tisn't declared. I'm using GCC with MINGW.
我在uint16_t未声明的地方遇到错误。我在 MINGW 中使用 GCC。
Heres the complete error.
这是完整的错误。
||In function 'print128_num':|

You need to include stdint.hor inttypes.hto get uint16_t.
您需要包含stdint.h或inttypes.h获取uint16_t.
