g++ - static => shl_load unsatisfied symbols

T Bruns — Mon, 13 Jul 2009 12:07:44 GMT

hello

i hava a problem.

i try to compile a programm with "-static" and then the linker come back with this error:

/usr/css/bin/ld: unsatisfied symbols
shl_load (first referenced in /usr/lib/libc.a(setlocale.o))
/usr/css/bin/ld: unsatisfied symbols
shl_unload (first referenced in /usr/lib/libc.a(setlocale.o))
/usr/css/bin/ld: unsatisfied symbols
shl_findsym (first referenced in /usr/lib/libc.a(setlocale.o))

HP-UX B 11.11
g++ 3.2

Libraries:
Xm, xerces-c Xt X11 Xp Xext phtread

Greetings
Thomas

That's correct. You can't use -static if you want to dynamically load something.
In order to use setlocale(3) and a bunch of networking functions, you must link with -l:libdld.sl.

mmhh that is not what i want :-(

i want some application which is fully linked static.

Background is, we produce on a HPUX PA-Risc and linked it fully static for an itanium Intel 64Bit.

Also we need all libs static :-(

Is there any way to do this?

thx

Hey Thomas,

> Also we need all libs static :-(

I think that could become difficult to get all required libraries as static ones.

As Dennis mentioned, some libraries should/must be shared because they a very specific for the system the run on (e.g. libnss). By the way, it is a bad idea to build a completely statically linked application (you may find some of these arguments useful: http://people.redhat.com/drepper/no_static_linking.html).

If you build your application on a PA-RISC system, you must have already set up your build environments with static/shared libraries and include header files for Itanium systems? Why don't you then just use the shared libraries? Probably the --sysroot option is useful for your case?

Best regards,
Andi

On IPF you can't do that since only libc.so is provided.

>we produce on a HP-UX PA-RISC and linked it fully static for Integrity.

You said you have done this before or it is failing now?

>Also we need all libs static :-(

You can only do this on PA and if you do, you must stub out setlocale and anything else that calls dlopen/shl_load. Or you must use static libs for all of your contributions but leave system libs as shlibs.

Hello ANdi

mmhh i don't now exactly if we need the itanium libs. Our point is we use the compatibility mode from the Itanium to run the APP, so we don't need the Itanium lib(?).

therefore i think we need the HPUX libs as static?

sorry for my english.

thx

it means that on the IPF the libc.so is provided and we don't link it static?

and the dld?

>You said you have done this before or it is >failing now?

now, is a new project.

ok i try this, but i don't find the flag for this option by gcc :-(
which flag is it?

thx

>I think we need the HP-UX libs as archive?

No, it means you need to copy your non-system PA shlibs to your IPF box.
Or you link your non-system libs as archive and the rest shared.

There isn't any for a foreign devil compiler. If you were using aC++, you would just use +A.

So you have to invent your own stubs.

Hey Thomas,

okay, sorry, then I just misunderstood you. I thought you were doing some cross-compiling on PA ...

You could check this page (http://h21007.www2.hp.com/portal/site/dspp/menuitem.863c3e4cbcdc3f3515b49c108973a801/?ciid=0208713ba4f02110713ba4f02110275d6e10RCRD) about ARIES ... I think you don't need the application to be linked statically to use ARIES.

See the example below

PA-RISC build:
hs0040:c5122564> uname -a
HP-UX hs0040 B.11.11 U 9000/800 151414671 unlimited-user license

hs0040> ./test

hey andi,

and this app runs on itanium without probs?

this is the same with my app and therefor it must run too!?

thx

Hey Thomas,

yes, I worked fine for me without any problems.
