As the message says, the object module oci.o needs to be recompiled
using +Z (HP compiler) or -fPIC (GCC).  You can't fix the problem
by changing the link command.

As far as I know, "-mminimal-toc" is not a GCC option applicable to the PA.

"-DPIC" doesn't change the behavior of the compiler.  Some code uses
to modify the code generated (asm) when PIC code is needed.  It won't
affect size of DLT.

You'd have to recompile the objects inside libocia.a using -fPIC.

hpux11.00 linking - Data Linkage Table (+z) overflow

[Mads]

Hello,

using
	bash-2.05$ gcc -v
	Reading specs from /data/mk/gcc/lib/gcc-lib/hppa1.1-hp-hpux11.00/3.2/specs
	Configured with:
../configure --prefix=/data/mk/gcc --enable-languages=c,c++ --with-gnu-as --
without-gnu-ld --disable-threads
	Thread model: single
	gcc version 3.2
	bash-2.05$

linking a big program using

	g++ -fPIC -Wl,+b/tmp/foo -Wl,+s ...

I get
	/usr/ccs/bin/ld: Data Linkage Table (+z) overflow in file
/data/mk/msgcc/OracleLib/libocic.a(oci.o) - use +Z option to recompile
	collect2: ld returned 1 exit status

Linking with

	g++ -fPIC -Wl,+b/tmp/foo -Wl,+s -mminimal-toc ...

makes no change. According to ps no +W is used? Shouldn't that be used
automatically?


I know -fPIC and that it should help. But I've also found DPIC mentioned -
what is that about?


http://gcc.gnu.org/install/specific.html#hppa*-hp-hpux11 says that

	GNU binutils 2.13 or later is recommended with the 64-bit port. The HP
assembler is not supported.
	It is highly recommended that the GNU linker be used as well.

That is only true for 64-bit? For 32-bit HP ld _must_ be used?


TIA,

Mads
