C++ compilation issue with <emmintrin.h> on Linux GCC

Question

Tried google and searched here, but no luck.

I am trying to port some windows codes that use to Linux.

Then I get a huge amount of compilation errors.

All I did was

#include <emmintrin.h>

And then :

g++ -c -pipe -march=i686 -mtune=generic -O2 -pipe -D_REENTRANT -w -D__SSE__ -D__SSE2__ -D__MMX__ -I/usr/share/qt/mkspecs/linux-g++ -I. -o .obj/Test.o Test.cpp

Am I missing some compiler option here ? Or I need to include some other headers ?

Answer 1

I believe you need to allow SSE instructions using -msse.
