Re: regarding shared object

Hi Ramesh,

> Is it similar to dll files in windows
You've answered you question :) yup, they are like dll's in Windows.

>How to compile the c code to .so .
if you have foo.c from which you want to build foo.so you'll need to :
cc -c foo.c
to get the object file. The .so is created at link stage (much like the
executables are). to get the .so you'll need to :
ld -shared foo.o 
other related options to ld would be -soname, and -o
Pls see man ld for more info.

To be able to use this your .so must have the appropriate hooks, and 
your appliation must make the right calls which varies from architecture
to architecture...
