All, I don't know if where this question should be asked here or PSoC Creator....but...

has anybody had problems with the sqrt() function? Here is a small test code to even see if it will compile and I get a "...undefined reference to `sqrt'..." error. The example is close to the Keil help context example.

Any sugestions?

float temp;
float Vmag;

void main()
{
    temp = 234.5;
    Vmag = sqrt(temp);

    for(;;)
    {
    }
}

Hi Keith,

It worked fine for me. Here is my Debugger window screenshot.

If you are still facing any issues, could you please send me your testing project?

Hi Keith,

Just now I realised that you are facing this issue with PSoC5 GCC Compiler and not with PSoC3 Keil Compiler. I have created a seperate project to test this and then I found out that it is because of math library not being included in GCC compiler.

Please refer to the KB article written by me for more details - http://www.cypress.com/?rID=42838

Kishore.

That was it, man.... what a relief. Why aren't things like this better documented?

Thanks again,

Keith

 I scoured the web for this. Now the log() function works just fine. Thanks for the pointer.
