Not able to create Oracle External Procedure to Run Host Commands

Question

Trying to follow this article

Its related to
Oracle External Procedure to Run Host Commands
steps
1)mkdir –p /u01/app/usfapp/oracle_external_procs/oracle_host
2)
Author is suggesting to create a file
but header file is missing in very first line... may be not sure..say it is <stdio.h>Create a file named oracle_host.c. The contents of this file will be:
#include
int RunCmd(char *cmd)
return(system(cmd));
4) Create the file named makefile. The contents of this file will be:
oracle_host: oracle_host.o
gcc -shared -o oracle_host.so oracle_host.o
$ cat makefile
oracle_host: oracle_host.o
     gcc -shared -o oracle_host.so oracle_host.o
5)
Now run the command make
The output on my server looks like:
[u01/app/usfapp/oracle_external_procs/oracle_host]
banner@usfbannerte [TRNG] > make
gcc -shared -o oracle_host.so oracle_host.o
here I stuck .. Not able to run this step ]$ make
gcc -shared -o oracle_host.so oracle_host.o
/usr/bin/ld: oracle_host.o: relocation R_X86_64_32 against `a local symbol' can not be used when making a shared object; recompile with -fPIC
oracle_host.o: could not read symbols: Bad value
collect2: ld returned 1 exit status
make: *** [oracle_host] Error 1
Any one has any idea what went wrong
