Hi,

I am using I.MX 6Q with Linux freescale 3.0.35-2508. I am trying to do some maths calculations, when i use sin,cos or sqrt function i am getting error.

Multiple markers at this line

- undefined reference to

`cos'

- undefined reference to

`sin'

I have included math.h header.

Kindly advice how to over come this issue,

Please use -lm option in GCC command line in order to include math libs.:
