C++ C++；与<；埃敏特林.h>；关于Linux-GCC

尝试谷歌搜索，但没有运气

我正在尝试移植一些用于Linux的windows代码

然后我得到了大量的编译错误

我所做的只是

#include <emmintrin.h>

---

我是否缺少一些编译器选项？或者我需要包含一些其他标题？

我认为您需要允许SSE指令使用

-msse

是，+1。使用-msse-msse2代替-D_uu-SSE_uu-D_u-SSE2_uu。

emmintrin.h

用于SSE2，因此它可能应该是

-msse2

酷！！错误消失了！你们太棒了！将在一分钟内标记答案。@Simon Richter，我对VS2010有一个类似的问题，msvc的编译器选项是什么？在项目属性中，在C/C++->“代码生成”下，有一个选项可以启用“扩展”指令集。值得注意的是@Paul R是正确的。应该使用-msse2-msse不起作用。
