c++ - 错误：调用 always_inline '__m128 _mm_cvtepi64_ps(__m128i)' 时内联失败：目标特定选项不匹配 _mm_cvtepi64_ps (__m128i __A)

Question

我不知道我为什么收到这条消息。我该如何解决？

g++ -c -o release/main.o main.cpp -Wall -fmessage-length=0 -march=native -O0

即使我更改了功能，我也总是遇到同样的错误。我在用着; <immintrin.h>、<xmmintrin.h>、<emmintrin.h>。我还看到一个可能的解决方案是在 file.pro 中添加：QMAKE_CXXFLAGS +=-msse3。但我不知道如何找到它。
