Hello,
I am trying to compile a project for STM32F103CB, but it doesn't seem to work properly. First of all, this project compiles and runs on IAR SDK. I ported it on uVision 5 SDK, and, after quite some pain, I made it compile. The problem is, I am still getting this warning:
Libraries\X_Lib\src\X_Configuration.c(438): warning: #223-D: function "roundf" declared implicitly GAverage[0] = (u32)(roundf((float)GAverage[0]/(float)(GSampleCount)));
although I am including the math.h file in X_Configuration.c:
#include <math.h>
in math.h, roundf is defined as
extern _ARMABI_FPEXCEPT double round(double /*x*/); extern _ARMABI_FPEXCEPT float roundf(float /*x*/); _ARMDEFLD1(round);
...what am I doing wrong? Is there some precise setting I overlooked?
Thanks a lot for your time!
How to do that? Because it looks like it finds the <math.h> include. In fact, it lists it under the dependencies of X_configuration.c, and it does not generate file-not-found error. In addition, I added all the necessary libs under C/C++ include path, and the compiler string shows -l C:\Keil\ARM, which is where the standard C library is supposed to be (well in a subfolder).
I am stuck.
