Application linker error in HP-itanuim

application not running — Wed, 06 Jan 2010 10:24:48 GMT

Hello all,
Usually our application build on HP-itanium and HP-PARISC. while executing the application on HP-itanium it gives unresolved linker error, but same application works fine in HP-PARISC.

Is there any specific build format change in HP-itanium while creating shared libraries?

Thanks

It might help if you offered any actual
information about what "our application
build" is doing, and what the actual error
message is.

Output from "uname -a" can be useful, too.

What language are you using? Where should that unsat be defined?
If this occurs at runtime, it is a dld error, not linker.
As Steven asked, what's the message?

Thanks for your prompt reply
Sorry for the confusion.
Due to security consideration , i couldn't explain the details about my application. I have tried to write sample application to recreate the same problem, but that works fine.

Here, i will explain you the scenario.

I have one shared library ' say libEx1' built with say 'libEx2' , libEx2 already built with say 'libEx3' , so we tried to attach libEx1 with our sample application. it gives following error.

"/usr/lib/hpux32/dld.so: Unsatisfied data symbol < symbol defined in libEx3> load module 'libEx1'"

I have seen this error only in HP-Itanium (HP-UX hbptc012 B.11.23 U ia64 2931400862 unlimited-user license) , where in HP-PARISC (HP-UX hindi B.11.23 U 9000/800 457514194 unlimited-user license) it works fine.

Thanks

>I have one shared library libEx1 built with say libEx2

libEx1 has a dependent shlib libEx2?

>dld.so: Unsatisfied data symbol load module libEx1"

Is this symbol exported from libEx3?

Yes, it is dependent.

>dld.so: Unsatisfied data symbol load module libEx1"

What tool are you using to check?
elfdump -n .dynsym -s load-module

What version of dld.so do you have? The latest patch is PHSS_39821.
