Hi there?

I would like to use some of math related function calls like pow, sin, sqrt...

But it seems math function doesn't work with SDK.

Either #include<math.h> on user_main or -lm on the Linker doesn't work too.

Do you have any idea to work them out?

Thanks

I have solved some part of it by simulating the math function though, still I would like to know how to link standard math.h or math library in sdk(if available)..

Thanks..

Thanks..

Code: Select all

`double pow(double x,double y)`

{

double z , p=1;

//y<0 ? z=-y : z=y ;

if(y<0)

z = fabs(y);

else

z = y;

for(int i=0; i<z ; ++i)

{

p *= x;

}

if(y<0)

return 1/p;

else

return p;

}

double fabs(double x)

{

return( x<0 ? -x : x );

}
