HPUX + shared libs

[Jakub Kocyk <Jakub dot Kocyk at comarch dot pl>]

Can I make "Position Independent Code" (PIC) using gcc v 2.8.1 or
egcs 2.95 on HPUX 11.00. I need it to build shared library which uses
functions
from stdlib. I made following:

compiled following code with: gcc -c runosgk.c

#include <stdio.h>

int RunOsGK(p1,p2,p3)
int p1;
int p2;
int p3;
{
printf("Ok!!!!!!!!!\n");
return 0;
}

void RunOsGK2(p1)
int p1;
{
int a,b;
a+b;
}

than i made librunosgk.sl with:
ld -b -o librunosgk.sl runosgk.o  -lc
than I compiled following:

int RunOsGK();
int RunOsGK2();
int main()
{
printf("Ty bucu lesny\n");

RunOsGK2(1);

printf("Ty bucu lesny\n");

RunOsGK(1,2,3);

return 0;
}

with:
gcc -o main main.c -lc -L. -lrunosgk 
and executed : ./main

root@posejdon:>./main 
Ty bucu lesny
Ty bucu lesny
Illegal instruction (core dumped)     <- these code is in RunOsGK in
printf
root@posejdon:>

but when i comment printf in RunOsGK:

#include <stdio.h>

int RunOsGK(p1,p2,p3)
int p1;
int p2;
int p3;
{
//printf("Ok!!!!!!!!!\n");

return 0;
}

void RunOsGK2(p1)
int p1;
{
int a,b;
a+b;
}

and make the same everythink is ok:
root@posejdon:>./main
Ty bucu lesny
Ty bucu lesny
root@posejdon:>

What I am doing wrong?
In HP told  me that i should use their HP ansi c compailer (but it
costs, i have only one short library to compile).
Is it posible to do this library using gcc? 

Than in advance for your help
