Use +z or +Z to recompile...

Use +z or +Z to recompile...

[Venkatakrishnan, V]

Hi,
	I'm using gcc ver 3.2 20020708 (experimental) on my HPUX 11.0 box.
	When building a shared library I get an error as follows....

/usr/ccs/bin/ld: DP relative code in file /var/tmp//ccCoJZUg.o - shared
library must be position independent.  Use +z or +Z to recompile.

	Now I'm already using the -fpic option while compiling my .c to .o
using which I then try to build my .sl, so I guess my object file is already
position independent.  Why the error during link though?
	Is there something I'm missing here??

Regards,
Venky

Use -fPIC rather than -fpic.

put

#ifndef INCL_H
#define INCL_H

at the top of incl.h

and

#endif // ifndef INCL_H

ad the end

Hi all,
I have this problem of linking error using gcc, I have 4 simple files
first.c (where main function is defined), and myfunc1, myfunc2 and
incl.h (which defines another function called basefunc). When I compile,
I get fatal error saying that multiply defined "basefunc". How to get
rid of this? 
Thanks
Best

Because code is also generated at link time to handle static constructors
and destructors.

Ah I see, now that I am using it during linking as well it worked, thanks
Jeff :).
But how come it wasn't sufficient to use it during compile only, why
explicitly at link as well??

Did you use it when linking your shared library as well?

Using -fPIC gives the same error.

Use -fPIC rather than -fpic.
