Hi, I would like to use the pointer to a float4 like this :

float4 f;
float4* pt = &f;

pt->x = 1.f;

But I got a compilation error !!

pt is not a pointer.  Try pt.x.

Sorry, I have corrected the example !

You are not allowed to use operator ->, I reckon. Just substitute it with (*pt).x = 1.f;

This is correct.  float4 is not a struct, it's a special vector type.  Thus, p->x doesn't make sense.
