ld: (Warning) Unsatisfied symbol

yazgoo — Thu, 19 Jul 2007 05:11:03 GMT

I'm upgrading VisiBroker from v5 to 6.5.
I installed v6.5.
Whan I compile via aCC I got a ton of this kind of warniings :

code_____________________________________________________________

ld: (Warning) Unsatisfied symbol "VISDLogProperty::set_source_enable(bool)" in file /opt/BES/lib/liborb64_r.sl
⌊_______________________________________________________________⌋

At runtime The following message occurs before an executable doesn't launch :

code_____________________________________________________________

/usr/lib/pa20_64/dld.sl: Unsatisfied data symbol '_log_enabled__13VISDLoggerMgr' in load module '/opt/BES/lib/liborb64_r.sl'.

Do you have an idea about what these warnings/errors mean and what I should do.

Hi,

check the vendor's site for prerequestions for this tool.
Check your patch level, maybe you need the newest patches for 'ld and linker',
for 11i it's PHSS_35383:
http://www8.itrc.hp.com/service/patch/patchDetail.do?patchid=PHSS_35383&sel={hpux:11.11,}&BC=main|search|

Also maybe LIBCL, libc cumulative, aCC patches.

Do a search in:

What VisiBroker shlib should these data items be defined?

Is liborb64_r.sl your shlib?
If you use "chatr -B immediate" on your executable, you may get more unsats. This may be interesting to see.

Here are the demangled data unsats:
VISDLoggerMgr::_log_enabled
LicenseConstants::PROD_ID_BES
LicenseConstants::FEATURE_VBC_ORB_SERVER
typeid

>Volkmar: Check your patch level, maybe you need the newest patches for 'ld and linker',

I'm not aware of anything that would cause unsats except for bad source or missing libs.

Oops, sorry I didn't explain my problem well.
What I meant is : I installed v 6.5; no problem.
Then I compile a program which uses visibroker 6.5 (which worked under v5), which gives me these logs.

Thanks

Your new info didn't provide any clues to your problem. Can you answer my questions?

Yes, it is.

That doesn't change anything the bin outputs

What should I do about those ?

Could you also explain what does this error means (I didn't understand).
Does it means the symbol exists in the shlib but not in something like an interface??

Thanks

Dennis Handly — Sat, 21 Jul 2007 02:23:45 GMT

>Yes, it is.

Then why are you using those (possibly obsolete) data symbols?

Were there only 5 unsat symbols or did you only list 5?

>That doesn't change anything the bin outputs

Ok, you don't have any more missing symbols.
But I would expect you to get an error on
VISDLogProperty::set_source_enable(bool) ??

>What should I do about those?

Those are the C++ data symbols that are missing. Where are you using these? Perhaps VisiBroker 6.5 no longer defines these classes and/or symbols.

>Could you also explain what does this error means. Does it means the symbol exists in the shlib but not in something like an interface??

It means that you are referencing symbols from your liborb64_r.sl, that are not defined in the VisiBroker shlibs.

Either they were removed in 6.5, or there could be more shlibs and you are not adding them to your link line.

If you could find the definitions of these symbols in 5, and then look at the same shlib for 6.5, perhaps you could get a clue.

Re: ld: (Warning) Unsatisfied symbol

yazgoo — Mon, 23 Jul 2007 02:58:52 GMT

1Â°) I grepped those symbols in my source files:

> VISDLoggerMgr
> _log_enabled
> LicenseConstants
> PROD_ID_BES
> LicenseConstants
> FEATURE_VBC_ORB_SERVER
> LicenseListener

And I've found nothing

For
> typeid
I've found it in a binary which overflows my command line

2Â°) Those are the only error. But there was a lot of warnings at compile time

I'm really lost...
Thanks anyway

Re: ld: (Warning) Unsatisfied symbol

yazgoo — Mon, 23 Jul 2007 03:19:00 GMT

Okay.
I've just grepped in both my old and new liborb64_r.sl most of the symbols.
The conclusion seems to be that those symbols are in liborb64_r.sl.new but not liborb64_r.sl.old .

What should I conclude from it?
I guess that means that the dependence that says which are the symbol availables in liborb64_r.sl.new is an old one.
Maybe I should give the compiling options.
I'll try and find those,

Thanks.

>I grepped those symbols in my source files

Try grepping at the output of:
$ nm -pxAN .../liborb64_r.sl

>I've found it in a binary which overflows my >(command line

Again look at the output of nm(1).

>that those symbols are in liborb64_r.sl.new

As unsats? (U)

>What should I conclude from it?

You need to know whether they are definitions or unsats. You need to search the VisiBroker shlibs.

Here is a little summing up of little things I had a look at in Visibroker lib dir.
If D means what I think it does, more includes may be necessarry.

But, once more, I don't see the problem.
These objects are not in use in my source.
Am I getting crazy?

Dennis Handly — Mon, 23 Jul 2007 19:56:20 GMT

>I have unsatisfied symbols in the new library. What should I do then?

You need to make sure you link against the Visibroker lib that defines them.

>I had a look at in Visibroker lib dir.
If D means what I think it does, more includes may be necessarry.

Yes more shlibs, you need to make sure that you use -lvdlog_pr, -lvdlog_r and -llmgr.sl on your link line.

>These objects are not in use in my source.

Sure they are. ;-)
You need to compile with -E -.i and you'll see they are in use by inlines, probably in the Visibroker include files.

I did solve my problem.
After many tries, here are the missing libs :
-lvdlog64_r
-llmgr64_cls

Thank you very much!

Closing because solved.
