math library in Intel Monitor Program

Hi, I would like to know how to include the math.h library in a simple c program to be played in the DE1-SoC computer based in Nios II (I need the sin function to create a musical note)

According to the laboratory exercise 8 of emmbedded systems, I have to add -lm at the additional compiler flag but I get the error:

"undefined reference to sin.."

what make me suspect that the math library is not being included in the program

what can I do?

thank you

    Hi @ruth,

    Thank you for posting in Intel community forum, hope this message find you well and apologies for the delayed in response.
    On the challenge to perform a sin function for c program, you may refer to the following sample code here.
    Basically it is just to include the math.h library to your code.
    Please do let us know if that helps to clarify your situation.

    Warm regards.
