CW 10.6 MQX 4.1.1 math functions

[gorakk]

I'm having some issues with math functions - possibly the same issue as seen in:

CW 10.6 Kinetis - "incompatible implicit declaration" of all math.h functions?

but the fix described in that post only causes more errors for me.

To make sure it wasn't just something wrong with my project I cloned the twrk60f120m BSP and then started a new project from the MQX gpio example.  To gpio.c I added:

#include <math.h>

#define PI 3.14159265

and in main_task():

    {

        double param, result;

        param = 30.0;

        result = sin( param * PI / 180 );

        printf( "The sine of %f degrees is %f.\n", param, result );

    }

This built with no errors but gave the following warning:

../Sources/gpio.c: In function 'main_task':

../Sources/gpio.c:78:9: warning: implicit declaration of function 'sin' [-Wimplicit-function-declaration]

After selecting "Enable automatic library configurations" as shown in that other post, I did a Clean Project and a Build Project and there were numerous errors as shown below.

Does anyone have any suggestions?

On a slightly tangential note: there is not much point using double if you are going to approximate pi to eight decimal places. Might as well use float, which will be faster too since the M4F FPU is single-precision.

Hi Allen,

Please grab ZIP and review MSWord document inside ZIP to see is it resolves your issue.

David,

Thanks for the info =)

What I ultimately did to solve the issue is described in this post:
