Compiler Error C2164

  • Artikkeli

'function' : intrinsic function not declared

An intrinsic pragma uses an undeclared function (only occurs with /Oi). Or, one of the compiler intrinsics was used without including its header file.

The following sample generates C2164:

// C2164.c
// compile with: /c
// processor: x86
// Uncomment the following line to resolve.
// #include "xmmintrin.h"
void b(float *p) {
   _mm_load_ss(p);   // C2164
}
