How to run a shared library on Open Solaris

Its is surprising that how is this possible to run a shared library.
Yes, its possible to run any shared library. I have done this R&D on Open Solaris.
It is also possible to run any shared library on Linux by using GNU Toolchain.
Please read my blog: How to run a shared library on Linux:
http://bhushanverma.blogspot.com/2008/06/how-to-run-shared-library-on-linux.html

There are some special shared object examples that can be run as an exectable:
On open solaris you can try to invoke run time linker (ld.so.1) direclty
$ /usr/lib/ld.so.1
usage: ld.so.1 [-e option,...] dynamic-object [object args,...]
Killed

To run any executable/application
$ /usr/lib/ld.so.1 ./appl

On linux you can run libc.so
$ /lib/libc.so.1
This will give you the version of libc library.

Shared object should have following entries to run:
1. +x permission that is by default is given by the static linker(program linker) when creating a shared object.
2. Entry point at which the program/shared library is starts to run.
3. Interpreter(Run time linker) that is used to run any shared library after loaded by kernel part exec().

By using static linker(program linker) option '-e entry_point', an entry point can be specified.
By using static linker(program linker) option '-I interpreter_path', an .interp section can be created that contains
the absolute path of the interpreter(run time linker).

You can see the interpreter path using following command
$ elfdump -i func.so

Interpreter Section: .interp
/usr/lib/ld.so.1

Demo on Open-Solaris machine
--------------------------------
$ cat func.c
#include
void bar();
int
func()
{
printf("Hacking\n");
bar();
exit (0);
}
void
bar()
{
printf("Bye...\n");
}

$ gcc -o func.so -shared -fPIC func.c
$ ./func.so
func.so: Bad entry point
Killed

$ gcc -o func.so -shared -fPIC func.c -Wl,-e,func
$ ./func.so
Segmentation Fault (core dumped)

$ gcc -o foo.so -shared -fPIC foo.c -Wl,-e,func -Wl,-I,/usr/lib/ld.so.1
$ ./func.so
Hacking
Bye...

Thats cool man, Now try yourself.
Happy hacking.
