Look in the Build Log (The Build Console ) or the Problems View to find the actual error you are encountering, rather than just looking at the final "error 1" message.

The most likely cause of problems calling sprintf() though are that you are linking with the wrong library variant. You need to use "nohost" or "semihost". For more details see:

What are none, nohost and semihost libraries?
Switching the selected C library

Alternatively, you might also want to check out the itoa() function:
