Math function

Hi folks,

I'm using CW10.2, MQX 3.8.1 amd a custom board with K60.

In one of source files I have the following statements:

#include <math.h>

float a, b, c;

...

a = powf( b, c );

When I build the project, the compiler gives me the error "function has no prototype" on that line. If I use pow function instead of powf function, no error comes.

Is there some settings I must do or some include file I'm missing?

Many thanks

Teckna

Upgrade:

If I enable the "Require function prototypes" flag, the error is present, but if I disable it, the error is not present: maybe there is a missing declaration in the include file?

I see the exact same issue with CW10.2, MQX 3.8.1 and a custom board with PX microcontroller. I installed CW10.3, but that didn't help. So far, I haven't found CW10's compiler error messages very helpful at describing what the actual problem is.
