Compile with mingw64 not found __builtin_ia32_paddsw128 #37

Closed frbitten closed 1 year ago

frbitten commented 1 year ago

I'm compiling the IntelRealsense SDK and I get this error in the mingw64 header when enabling SSE instructions.

I'm using the Mysys2 framework with mingw64.

Why is the function __builtin_ia32_paddsw128 not found? Is there any auxiliary library missing?
