Dear Vino,

    I tried with these two commands to create shared library..

1.gcc -fPIC -g -c -Wall hello.c
2. gcc -shared -Wl,-soname,libmystuff.so.1 -o libmystuff.so.1.0.1 hello.o -lc

But when I am trying the second command It is showing the following errors.

ld: warning: option -o appears more than once, first setting taken
ld: fatal: file libmystuff.so.1: open failed: No such file or directory
ld: fatal: File processing errors. No output written to libmystuff.so.1.0.1
collect2: ld returned 1 exit status

I am using UNIX.

Please need help ......
