[Standalone Program] simple I/O using hyperterminal

Question

Hi,
I am trying to create simple standalone program to get some values from keyboard via hyperterminal and let Opensparc on FPGA do the processing and then display the result back in hyperterminal. I have sunStudio compiler. However, it seems scanf is not recognized by the compiler?
/home/ssoekamt/sparct1/design/sys/edk/examples/src/simple_add
/opt/sunstudio12.1/bin/cc -xarch=v9 -I../include -errwarn=%all -xO2 -c simple_add.c
cc: Warning: -xarch=v9 is deprecated, use -m64 to create 64-bit programs
/usr/ccs/bin/ld -64 -e start -dn -M ../mapfile -o simpleadd -z allextract -L ../libos -los simple_add.o -L ../libc -lc
Undefined               first referenced
symbol                in file
scanf simple_add.o
ld: fatal: Symbol referencing errors. No output written to simple_add
*** Error code 1
make: Fatal error: Command failed for target `simple_add'
Current working directory /home/ssoekamt/sparct1/design/sys/edk/examples/src/simple_add
*** Error code 1
The following command caused the error:
cd simple_add && pwd && make install
make: Fatal error: Command failed for target `simple_add'
When I commented out all scanf statements in the codes, everything is working.
any thought?
Thank you.

I did try this, but the same problem occurs
public static void main(String[] args) {
try {
file = new File(args[0]);
outFile = new File("StoredProcstemp.txt");
fr = new FileReader(file);
in = new BufferedReader(fr);
fw = new FileWriter(outFile);
pw = new PrintWriter(fw);
// x=0;
while ((holder = in.readLine())!=null) {
System.out.println("myholder"+holder);
System.out.println(holder);
pw.write(holder);
// pw.print(holder);
} // end while
in.close();
fr.close();
fw.close();
pw.close();
catch (IOException e) {
