using sprintf "undefined reference to `_sbrk'"

[spomue]

I want to use the sprintf-Funktion. But if I use it like

char   str[128];
sprintf(str, "%s: Vers: %s, %s %s\r", GSE_SOFTW_NAME, GSE_FW_VERSION, __DATE__, __TIME__);

I get the error msg: undefined reference to `_sbrk'

What is the Problem?? Please can help me anybody?

Thanks

Try adding #include <unistd.h>.

Doesn't work.
And sscanf also generate this error.

Wrong compiler version, wrong lib, wrong command line or the like.

OK. But what can I do to use sscanf or sprintf or other functions?

Find what you've done wrong as I posted.
