Hello all,

I am trying to build a shared library. The compiler driver invokes the
linker and the linker string looks as below:-

/usr/ccs/bin/ld /opt/langtools/lib/crt0.o -u main -b -B symbolic
+vnocompatwarnings -z +s +h libxxx.sl -o libxxx.sl -Fl libyyy.a -L. +s
-ldld -lc

And, I get the following error:-
/usr/ccs/bin/ld: DP relative code in file /opt/langtools/lib/crt0.o -
shared library must be position independent. Use +z or +Z to recompile.

The object files in the archive libyyy.a are all built in PIC mode.
AFAIK, we can't change the startup file crt0.o, so is there a way out?

Secondly, what I feel is that crt0.o should not be linked while
building a shared library. It is exclusively for building executables.
I am unable to figure out from where is this crt0.o is getting linked.
Is it because of the usage of "-u main" option?

Machine specifics:-
HP-UX 11.00 PA-RISC 2.0
Compiler: HP92453-01 A.11.01.21505.GP (Native compiler)

Kindly suggest.
Thanks,
Anunay

You should be linking with /opt/langtools/lib/scrt0.o
while creating shared library.

So, how do i get rid of that "position independent" error?

Your compiler is too old, and doesn't understand '-b' flag.

This is one (rare) case where you have to bypass the compiler driver
and link your shared library directly with 'ld'.

Yes, PHSS_21505 doesn't understand -b and using -Wl,-b just confuses the
linker and cc.

Which patch should I install to update the compiler?

You can't. The last patch for that version of the compiler is PHSS_25171
and that still doesn't support -b.

You must purchase a new compiler. Or if you have a compiler support contract
you can get the latest update:
